From starring in Coca-Cola ads to becoming the poster child for climate change, the polar bear is quite the high-profile species. Ursus maritimus is a fascinating animal that roams across the Arctic Circle through Norway, Russia, Canada, Greenland, and Alaska, and there's more to them than the adorable faces you see in children's books and advertisements. In honor of International Polar Bear Day, which takes place on February 27, here are 25 things you should know about the fascinating animal.

1. They're the largest carnivores on land.

Polar bears can weigh more than 1300 pounds and span more than 8 feet, 6 inches from nose to tail, making them the largest carnivores to currently walk the Earth. (Though other bears can grow larger, like Alaska's 10-foot-long Kodiak bear, they're omnivorous, while polar bears prefer an all-meat diet.) The males far outweigh their female counterparts, who may only weigh between 330 and 650 pounds. In general, though, a bear's weight fluctuates significantly throughout the year, with some bears packing on 50 percent more body weight over the course of a successful hunting season, then losing it over the course of their long fasting months.

2. But technically, they're marine mammals.

Because they spend so much of their lives on ice, rather than land, polar bears are the only bears to be considered marine mammals. They hunt, court, and mate out on the ice, spending many months of the year far from land.

3. They're higher on the food chain than we are.

Human beings aren't as high on the global food chain as you might think. Polar bears don't have any natural predators, and their intensely carnivorous diet puts them at the top of the food chain with species like killer whales, according to researchers, while humans fall somewhere closer to the middle. Don't worry too much about getting eaten by one, though—a 2017 study found that during the past 144 years, there have only been 20 fatal polar bear attacks in all of the five countries that have polar bear populations. However, as food becomes more scarce for the bears, humans living in polar territory may soon face more risk from starving bears.

4. They're loners ...

Other than the two to three years a cub spends with its mother, polar bears are pretty much solitary creatures. Adults spend only a few days a year mating, then go on their own way, spreading out to hunt on their own. They rely on the scent left by the sweat glands on their paws to track other bears, using the smell to sense where potential mates might be headed, among other things.

5. ... but are sometimes willing to share.

Polar bears can play nice with each other sometimes. On occasion, they will hang out together in large groups, especially if there's a big meal that multiple bears can take part in, like a whale carcass. When they do spend time together (in what's called a sleuth), male bears will play-fight with each other, wrestling and swatting at each other without doing any real harm. According to the documentary Polar Bears: Spy on the Ice, polar bears can recognize friends they've met before even if they go without seeing each other for many years.

6. They're picky eaters.

When food is plentiful, polar bears are very selective about what they eat. They hunt seals, but if there are plenty available to hunt, they won't eat their whole catch. Instead, they'll only eat the energy-rich blubber (up to 100 pounds at a time), leaving the rest of the carcass for other animals to scavenge. When hunting is good, their diet is made up of about 90 to 95 percent fat. When times are lean, though, they'll happily branch out, eating reindeer, rodents, eggs, seaweed, and anything else they can get their claws on. However, because their bodies are so much better at digesting fat than protein, researchers think that if Arctic ice continues to melt and polar bears become unable access the ice (with its blubber-rich seals), they won't be able to get enough calories on land to survive [PDF].

7. They spend a lot of time fasting.

When they're not out on the ice scoping out seals, polar bears spend an incredible amount of time fasting. The female polar bears fast longer than any other mammal species—in Canada's Hudson Bay, pregnant polar bears can fast up to 240 days, or almost eight months. There's reason to think they'll be fasting even longer in the future as sea ice melts, leaving bears with fewer hunting opportunities and less time to accumulate the fat stores needed to get through the lean months. During the 1980s, non-pregnant polar bears spent 120 days fasting between hunting seasons, but researchers now think that the bears will have to go without food longer and longer, fasting for as much as 180 days at a time in the future.

8. They will travel far to find dinner.

The average bear might travel across 100,000 square miles in its lifetime, and that number may be getting higher. In 2013, a bear searcher told the BBC that polar bears were spending 9 to 13 percent more time being active to make up for the fact that the ice they hunt on is drifting faster, leaving them walking on a "treadmill" just to stay within their territory. One bear tracked by the WWF traveled almost 2300 miles from Norway to Russia in less than a year. Due to receding ice, polar bears have to walk farther to find prey, wasting valuable energy. The energy they gain from eating a single ringed seal might not even make up for what they expend trying to find and catch it.

9. They can swim for days.

Polar bears are savvy swimmers, paddling at an average speed of 6 miles per hour. And it's a good thing: Due to all that melting ice, polar bears are putting their swimming skills to lengthy use. In 2011, a study reported that a tagged female polar bear swam a total of 426 miles in one nine-day stretch across the Beaufort Sea above Alaska, losing 22 percent of her body weight in the process. Another bear in the study swam for 12 days, though she at least stopped to take some breaks.

10. They get hot fast.

You'd think with all that plunging in Arctic waters, polar bears might get chilly occasionally. But since they're built to withstand extreme cold on a regular basis, they actually have the opposite problem: They overheat very easily, and are more likely to die from the heat than the cold. Their two layers of fur and solid layer of body fat (up to 4.5 inches thick) keep their metabolic rate consistent when temperatures reach as low as -34° F. They can sprint up to 30 miles per hour if need be, but much like you wouldn't want to run a race in a heavy ski jacket, polar bears can't spend much time chasing after their prey lest they overheat—a bear's body temperature can rise to feverish temps if they move too fast. On land, they typically only walk at speeds of three miles an hour, and their main hunting technique involves staying very still for hours or days at a time, waiting for a seal to emerge from the ice to breathe.

11. They've been getting it on with grizzlies.

In addition to changing their travel patterns and dinner prospects, climate change is altering polar bears' love lives. As the ice-traversing bears are forced to spend more time on the tundra, their habitats are starting to overlap with those of grizzly bears. In some places, the two species are getting more comfortable with each other, with amorous results. In Alaska and western Canada, grizzlies and polar bears are doing more cross-breeding, creating hybrid offspring.

12. They grow a lot in their first few months.

At birth, polar bears weigh anywhere from 16 to 24 ounces—about what a guinea pig does. As newborns, they're blind, toothless, and only about a foot long. But by the time they emerge from their den for the first time around four months later, they are substantially larger, weighing between 22 and 33 pounds. In addition to nursing, they'll begin eating solid food around that time, and by 8 months old, they'll weigh 100 pounds or more.

13. They have huge feet.

In order to balance on ice, polar bears boast giant feet. Their paws can measure up to 12 inches in diameter, acting like snowshoes to spread out their weight on thin ice and deep snow. The bumpy papillae (like the ones on your tongue) on their footpads help grip the ice, keeping them from sliding around. They also have long, curved claws that can measure almost 4 inches—all the better to grab onto slippery seals.

14. They don't hibernate.

While black bears, grizzlies, and other bear species spend each winter denning, forgoing eating, drinking, moving, pooping, and peeing for months on end, polar bears stay active all winter. Polar bears don't need to sleep through the winter, though, because there's plenty of food available to them in the coldest months, when they take to the sea ice to hunt for seals. The only exception is during pregnancy, when a female polar bear digs herself a den and remains sealed inside, surviving off her stores of fat, until her cubs grow large enough to survive outdoors.

15. They love to nap during snowstorms.

Polar bears may not hibernate, but they are happy to lay low when bad weather hits. During the winter, they dig themselves into shallow pits in the snow to protect themselves from wind, sometimes remaining there for days as the snow piles up on top of them like a warm blanket. Sometimes, they take a similar approach to staying cool, digging through the tundra down to the permafrost during the summer to keep from overheating.

16. They're very hard to track.

Considering how far they travel—both walking and swimming—over a given year, you can imagine how hard it is for scientists to track polar bears. By nature, they spend a huge amount of time alone in remote locations. Scientists use boats, helicopters, and low-flying planes to observe them, but that only works in good weather and in certain locations. So recently, they've turned to satellites, fitting bears with non-invasive radio collars and tracking them through high-resolution satellite imagery. It's cheaper than sending out a helicopter, and it lets researchers identify bears even in the most remote areas of the Arctic.

17. Their nostrils close while they swim.

Polar bears don't have to worry about getting water up their nose. When they swim, their nostrils close to prevent them from breathing in water. They can swim at depths up to 15 feet, and while they typically only dive for a few seconds, they can hold their breath for more than two minutes, enabling them to sneak up on seals resting on ice floes. In 2015, scientists reported observing a record-breaking polar bear dive that totaled 3 minutes and 10 seconds. The hungry bear stalked three seals from afar, swimming almost 150 feet underwater without surfacing for a breath or to reorient himself to the seals' location before bursting out of the water where one of the seals was resting. (Sadly, his prey got away.)

18. They can turn green in captivity.

Though polar bears are sometimes known as the white bear, they aren't white. Their hair is colorless and hollow, and only appears white because of the way light scatters through their fur. (Under that mass of hair, their skin is as black as their noses.) When bears are subject to warmer temperatures in captivity, though, they can take on a bit of a verdant hue. Algae infestations can turn polar bears green, and not just on the outer layer of their fur. The colorful algae grows inside the hollow tube of each hair. This green growth thrives in humid climates, like Singapore, where the bears don't naturally live.

19. They'll never meet a penguin.

Though you might see polar bears and penguins together in Coca-Cola ads or on winter-themed pajamas, the two species never mix in real life. They live at opposite ends of the Earth, though they both spend their days in icy waters. Polar bears exclusively inhabit the Arctic, and penguins only live in the Southern Hemisphere. The closest they ever get is when they live in the same zoo.

20. At one zoo, they poop glitter.

At the Assiniboine Park Zoo in Winnipeg, Canada, the polar bears have sparkly poop. In 2014, zookeepers began feeding each of their bears a different color of non-toxic glitter so that they could trace their bowel movements, analyzing the samples to identify health issues, track stress hormones, and generally see how the bears are dealing with zoo life. The colors help the zookeepers label which poop comes from which bear.

21. Europeans have kept them in captivity since the 13th century.

Captive polar bears have piqued public curiosity since as early as the Middle Ages, when the bears were occasionally given to European royalty by Viking traders. In the 1200s, when Henry III kept one in London, it was muzzled and chained but allowed to catch fish and swim in the Thames River. In the 17th century, Frederick I of Prussia kept a defanged and declawed polar bear, staging public fights between it and other large mammals for public amusement.

22. Posing with them was once a popular German pastime.

In the early 20th century, getting a picture with a man dressed in a polar bear suit was a fairly standard activity in Germany, at least according to the many photos found by French photo collector Jeann-Marie Donat. Donat spent 20 years tracking down the vintage photos, taken between 1920 and 1960, for his 2016 book Teddybär. There are several potential explanations for why so many Germans elected to stop for photos with people in polar bear suits (or to dress up as polar bears themselves). Donat suggests that it might trace back to the popularity of the two polar bears that arrived at the Berlin Zoo in the 1920s, while Hyperallergic notes that the costume was created as a Fanta advertising stunt, designed to distract Germans from the horrors of World War II. The photos show people young and old posing next to bears at the beach, in parks, in the street, in the summer and winter, alone and in groups. They all look delighted to get a chance at a polar-bear souvenir.

23. They can be ... polarizing.

Knut, a polar bear cub born at the Berlin Zoological Garden in 2006, was hand-raised by zookeepers after being abandoned by his mother at birth. The cute cub became an instant tourist attraction—the most famous bear in the world, even—and the zoo's attendance rates skyrocketed, netting an extra $1.35 million in tickets when the bear began making twice-a-day public appearances.

But not everyone was psyched about "Knutmania." The young bear's popularity proved to be controversial for animal rights organizations like PETA, whose German spokesperson Frank Albrecht said the zoo should have let the orphaned Knut die rather than continue hand-feeding him, a process that he called a "gross violation of animal protection laws." In 2007, the bear received an anonymous, handwritten death threat from a hater who simply wrote "Knut is dead! Thursday midday." The zoo took the fax seriously enough to assign triple the amount of zookeepers keeping watch over the polar bear during his daily public romp. (Knut continued to live at the Berlin zoo until his death at age 4 from an autoimmune disease.)

24. They sometimes get the celebrity treatment.

In 2007, celebrity photographer Annie Leibovitz photographed Knut for the cover of Vanity Fair's annual "Green" issue. While Knut appeared solo on the cover of the German edition, he was Photoshopped into an image with Leonardo DiCaprio for the American edition. After his death, the Berlin zoo erected a bronze statue in his honor, and his body was preserved for display at the city’s natural history museum.

25. Churchill, Canada has a unique way of living with them.

Churchill, a town in Manitoba, Canada on the shores of the Hudson Bay, is known as the polar bear capital of the world. During the fall, hundreds of polar bears pass through on their way to their icy hunting grounds on the bay, waiting nearby as the ice hardens for the winter. The locals have adopted unique ways of living with the hungry bears. Many don't lock their doors, so that if someone is running away from a polar bear, they can duck into any doorway. Since Halloween falls right in the middle of polar bear season in town, city employees, police officers, volunteer fire officials, and polar bear conservationists stay on patrol to drive away any bears that might be tempted to go trick-or-treating themselves, using helicopters, sirens, air horns, rubber bullets, and more to keep the bears at bay. Kids, for their part, aren't allowed to wear anything white for the evening.

Churchill also runs a "polar bear jail" for bears that continue to wander into town. Residents are encouraged to call the Polar Bear Alert Program hotline year-round if they see a bear in town, and conservation officers will come and try to scare it away. If shooting loud scare rounds at the bear doesn't do the trick, they trap the bear, or, if all else fails, hit it with a tranquilizer dart and take it to the Polar Bear Holding Facility. The specially-designed compound can hold up to 30 bears and is meant to keep bears that are aggressive or persistently return to the community. When the bay freezes, these bears are transported by helicopter or vehicle onto the ice, where they resume their normal winter hunting routine. With warmer temperatures keeping bears off the ice for longer and longer periods, more towns may soon have to learn from Churchill's strategies for peaceful coexistence.

YouTube Star Coyote Peterson Brings 'Misunderstood' Animals to His New Animal Planet Series

Animal Planet
Animal Planet

As host of the popular YouTube series Brave Wilderness, Coyote Peterson is no stranger to going face-to-face with creatures many deem terrifying—think great white sharks and pit vipers—but that he says are simply "misunderstood."

Animals have always been a big part of Peterson's life, even before he made a career out of being stung and bitten by ferocious critters. The Ohio native studied video production and directing at Ohio State University, and then decided to combine his two passions—film and all things wild—to teach viewers about wildlife and the importance of conservation. His YouTube channel currently has more than 15 million subscribers.

Now Peterson is embarking on a new adventure with Animal Planet in the show Brave the Wild. He'll travel all over the world with wildlife biologist Mario Aldecoa and his crew, sharing creatures that aren't often in the spotlight and that viewers may find a little frightening. He recently chatted with Mental Floss about the importance of conservation, his thing for snapping turtles, and his close encounter with a jaguar and her three cubs.

You’ve said your love of animals started with snapping turtles. Can you talk about the first time you saw one and what about them fascinated you so much?

The first snapping turtle I caught was when I was only 8 years old. I was always fascinated with turtles, because at first glance they look prehistoric, almost dinosaur-like. Growing up in Ohio, I never got to see any "exotic" animals. My favorite thing to watch on TV was Steve Irwin. Watching him wrestle crocs is what inspired me to catch my first snapping turtle, the most dangerous animal Ohio has to offer.

In Brave the Wild, you introduce animals that are often feared or misunderstood. What's the importance in exposing viewers to these creatures?

One of my goals through this series was to inspire people to overcome their fears of these seemingly dangerous animals and learn to admire them from a safe distance. The more you understand these creatures, the less you are afraid of them. One of the messages I try to convey in every episode is the importance of conservation.

What’s the most "misunderstood" creature you've encountered?

The most misunderstood creature that comes to mind is the carpet shark, which we filmed in season one. As I always say, people’s biggest fears are the three S’s (sharks, snakes and spiders). The carpet shark is found off the coast of Australia. They only bite humans in the case of mistaken identity. To some of these sharks a person’s foot might look like a fish. Any time you enter a new environment you need to be aware of what you need to look for, not only to keep yourself safe, but the animal as well.

What goes into preparing for each encounter to make sure you and the animals come out alive?

With any new expedition, you need to come into the environment knowing exactly what to expect. When encountering a new animal, I try to stay as calm as I can and have no hesitation. If I stay calm, the animal stays calm, [and] I'm creating a safer interaction for myself. I use different tactics when I encounter different animals. It also depends on whether the environment is land or in water.

How do you keep your composure on camera when you're in a potentially dangerous situation?

Any situation I find myself in, I look at it as my job. For example, I would be afraid operating a crane, because that is something I don't do. If it's part of your job, it's something that you get used to. When I do my job, I make sure I'm focused and never hesitate. Before I encounter any animal, I know what I'm going to say to the camera. I say that, for the best show, we always need to have the camera rolling so the audience can see what is happening.

Animal Planet

You were in Australia filming Brave the Wild during bushfire season. What was that like?

Visiting Australia was one of the best experiences I had filming the show. Australia is a fascinating country that has so many unique environments. We spent over 50 days in Australia and encountered more than 35 different species. We were there right before all these devastating fires started, and we got to witness the severity of the drought and all the different animals it impacted.

What was your favorite animal encounter in upcoming series?

Each encounter I have in the wild is special. I would have to say that the most exciting moment for me was when we were filming in Brazil and I saw a jaguar and three of her cubs up close. Not only did I get to see this in real life, but my amazing team was able to capture this special moment on tape. It is just so amazing seeing these animals survive and thrive in the wild while dealing with not only the dangers of the wild but human encroachment as well. Hands down, this was my favorite episode that we got to film.

10 Secrets of Seeing Eye Dog Trainers

The Seeing Eye

Founded in 1929, The Seeing Eye is a nonprofit in Morristown, New Jersey, that trains guide dogs to help their blind owners navigate the world safely. In order to make sure each dog is ready for all the obstacles and challenges that come with leading the visually impaired, instructors train them in both real-world settings and simulations at The Seeing Eye's campus. It's a system that has worked for over 90 years.

“It’s the oldest guide dog school, and we’ve been honing this very specific process of training a dog to do very specific tasks,” Brian O’Neal, a guide dog mobility instructor with The Seeing Eye for nine years, tells Mental Floss. “We have a road map.”

Seeing Eye dogs are venerated; in January 2020, New Jersey proclaimed them the official state dog. And legally, no guide dog can even be called a "Seeing Eye dog" unless it graduated from the school itself. Though the dogs that come out of the school have garnered plenty of attention, the dedicated instructors who prepare them for working life are less well-known. We spoke with three trainers from The Seeing Eye about why certain breeds make great guide dogs, how they keep their owner’s safe from low-hanging branches, and whether or not they can read cross signals (spoilers: They can’t).

1. It takes years of apprentice work to become a Seeing Eye Instructor.

Being a Seeing Eye instructor isn't a volunteer position anyone can sign up for—it's a full-time job. If you meet the basic requirements, such as having a four-year Bachelor’s degree, you can apply to become an instructor. Once you make it through the application process, you go through a three-year apprenticeship program in order to become an official trainer. The apprenticeship includes classes and exams, as well as hands-on training with dogs and students, The Seeing Eye’s name for blind people preparing to become guide dog owners.

The work doesn’t become any less intense when apprentices graduate to full-fledged instructors. From 7:45 a.m. to 4:30 p.m., they train, exercise, and care for eight dogs total—four in the morning and four in the afternoon. If you aren’t ready to commit to working for The Seeing Eye full-time, you can volunteer to be a puppy raiser and foster future guide dogs in your own home.

2. Seeing Eye dog instructors also train the dog owners.

The dogs and their trainers aren’t the only ones working hard at The Seeing Eye. Before a blind person can take a guide dog home, they must live on the campus and go through weeks of training to learn all the intricacies of working with their dog, including navigation and bonding.

“A student is someone who’s applied to our school and [has] been accepted to our program, and we’ve flown them here or provided travel to come here,” O’Neal explains. “We match them with a dog, and over 27 days, we teach them how to safely and effectively work with this dog and vice versa. Once they’ve completed the program, they become graduates.” But to get there, the instructors, students, and their dogs have to put in long hours.

“Class is emotionally and physically exhausting," Sarah Indano, who's been in the apprenticeship program for two and a half years, tells Mental Floss. "It's like boot camp to really train these people for everything they need in a limited amount of time."

3. The Seeing Eye instructors only work with dogs bred by the organization.

The Seeing Eye

The Seeing Eye breeds all its own dogs at a center in Chester, New Jersey, and each must meet a strict set of requirements to become a part of the breeding program. “All the dogs are medically tested and their temperaments are also tested,” Ruthanne Dewey, a guide dog mobility instructor at The Seeing Eye for more than six years, tells Mental Floss. “The best of the best are selected to go into that breeding program.”

Even with the proper pedigree, not every dog the organization breeds is fit to be a guide animal. At 7 weeks old, dogs are sent to live with volunteers called puppy raisers who provide them with care and teach them basic commands. When the dogs are about 14 months old, they receive medical testing to determine if they’re fit enough to train to be guide dogs. From there, the training, which O'Neal says involves a lot of "repetition and consistency," lasts four months.

4. Instructors typically work with a handful of choice breeds.

Seeing Eye dogs almost always belong to the following groups: Labrador retrievers, golden retrievers, German shepherds, or any mix of those breeds. Both physically and personality-wise, these breeds produce the best dogs for the job. “They are working breeds,” O’Neal says. “They have a long history of work and working alongside humans in varying capacities. So it comes down to their drive to work as well as their incredible temperament.”

This drive to work often translates to a desire to please their humans. As O’Neal states, trainers can only teach dogs so much, and an animal’s need to keep their owner happy is what ultimately allows them to do their job well. “They want to get the praise from that person. They want to figure out, ‘what does this person want me to do? Because I’ll do it.’”

These breeds also fit the physical requirements for a guide animal: They’re big enough to lead a person down the street or block them from traffic, but at the same time, small enough to fit on public transportation or beneath an office desk.

5. Praise is crucial during the training process.

Seeing Eye dogs may not know the directions to the supermarket, but they're trained to learn other tasks that enable their owners to move through their environments with confidence and security. These include stopping short of curbs, moving around objects, and blocking people from walking in front of vehicles. Dogs learn these skills through positive reinforcement—as much as it takes to make the behaviors second-nature.

“When the dog does something right, we’re showering it with love and affection telling it did a great job, and if it didn’t do a great job, we’re telling it ‘no, we don’t do it that way,’ and we’ll always go back and give them the chance to be successful,” O’Neal explains. “That’s important, because if we just said 'no' and moved on, I could see animals being discouraged by that."

6. Seeing Eye instructors can’t teach dogs to read street signs.

A Seeing Eye dog can navigate obstacles on a sidewalk, or stop a person from stumbling off a curb, but Seeing Eye instructors can't train them to replace a GPS. “I get asked all the time how the dog can read the stop light and know that green means go and red means stop,” Dewey says. “I always explain to people that it is not the dog that decides when to cross the street. The dog doesn’t know how to get to the grocery store. All that falls on the person. The blind person has to be able to cross the street safely.”

7. The Seeing Eye has escalators and Priuses on campus to simulate real-world obstacles.

The more advanced stages of Seeing Eye dog training take place in urban areas, starting in the center of Morristown and culminating in trips to New York City. But before the dogs are ready to enter the real world, trainers find ways to recreate those environments on the campus.

“We have our own maintenance department and mechanic that is in charge of our own fleet of vehicles,” O'Neal says. These cars are used to prepare dogs for the type of traffic they'll encounter when guiding their owners in public. “We also have Priuses so we can make sure the dogs are learning to steer clear of cars that are silent as well.”

The campus also has plenty of indoor obstacles designed for training, like staircases and an escalator that's housed on the grounds.

8. Some obstacles require some surprising training equipment.

Training a dog to look out for objects in front of it—like cars or pedestrians—is fairly straightforward. Making sure they’re aware of obstacles above ground-level poses more of a challenge to instructors. For these lessons, trainers use some unexpected equipment. “We have an obstacle course with overhead pool noodles that stick out to make sure the dogs are watching out for the top part of the person, too,” O'Neal says.

Instructors don’t know what size a dog’s owner will be during the training process, but that hasn't been a problem so far. Incredibly, the dogs are able to figure out the height and width of their humans on their own. “If you’re an instructor that’s really short, but that dog goes to a person that’s really tall, that dog quickly learns and adapts that they have to look out for [obstacles] that are much higher,” O'Neal says. “To me that’s one of the most amazing parts of the job; how much the dogs adapt and do on their own that we don’t teach them and can’t teach them.”

9. Seeing Eye apprentices take classes on the human eye to learn more about visual impairments.

Every instructor’s apprenticeship includes courses on dogs and dog training, but they also take classes to learn about the vision issues faced by the students. “I’m currently studying for my second exam, which is on the human eye and diseases and disorders of the eye and optic nerve,” Indano says, likening these classes to a college course. “It gives us the basis of the language we use to communicate with our students. We’re reminded that not only do our students see us as dog professionals, but they also see us as vision professionals, as well.”

This level of understanding is made even greater during Blindfold Week—which exactly what it sounds like. “We wear a completely dark blindfold for one week, and we live with the students for the first week of class,” Indano says. “We’re given some prep on how to effectively use a cane for travel for the first two days of class, and are taught how to cross streets, how to judge traffic, and keep ourselves safe."

The apprentices are even paired with a dog during Blindfold Week, effectively putting them through the same training as the students. "It gives you a lot of insight into what these students are going through," Indano says.

Seeing Eye dogs don’t have the time to chase squirrels, accept pets from strangers, or sniff trash cans when they’re on the job, but that doesn’t mean they never get to enjoy being a regular dog.

“People think these dogs don’t ever get a break,” Indano says. “They put on their business suits, which for them is their harness, and they’re at work. When they go home, their business suit comes off, and they get to be a dog that their person can snuggle and give pets to and play fetch with ... They live and love to work for their owners, and they get to go home and get even more love.”
