6 Popular Dog Myths, Debunked

You know that your dog is the cutest, funniest, most lovable pooch on the planet, but there's probably a lot you don't know about man's best friend. Over the years, a surprising amount of misinformation has been repeated enough about these furry little creatures to make it seem like fact. Petful took some time to debunk several popular myths about dogs that are just that—myths.

1. Dogs are completely color blind.

While many movies have tried to convince us that dogs are completely color blind, that actually isn't true. Dogs are partially color blind, but have the ability to see yellow, green, and blue or combinations of those colors. As motion and brightness are more important for dogs, their partial color blindness does not affect them much.

2. A dog's mouth is cleaner than a human's mouth.

While most germs in a dog's mouth are dog-specific and harmless to a human being, that doesn't mean that a dog's mouth is actually cleaner than a human's. They're both filled with a fairly equal amount of bacteria—not all of which can be transmitted between species. But a dog licks many things that most people would not want on or near their face (especially those puppers who like to go digging through the trash), so it's always a good idea to keep any smooching sessions with your dog to a minimum—especially because a dog can transfer bacteria to a human that could result in an infection.

3. One human year equals seven dog years.

Many dog owners automatically give two ages when asked how old their dog is: human years and "dog years" (the latter of which they calculate as human years times seven). According to Jesse Grady, clinical instructor of veterinary medicine at Mississippi State University, the best way to describe a dog's age is to sort it into a category.

The American Animal Hospital Association Canine Life Stages Guidelines [PDF] is what many veterinarians use to treat their patients. This list divides a dog's lifespan into six stages: puppy, junior, adult, mature, senior, and geriatric. And rate of maturation looks a lot different in dogs than it does in people. It takes a less than a year for a dog to reach the adult stage, and after that it takes nearly six years for it to move on to the mature stage of its life. In other words: "Dog years" depend on the dog itself.

4. A dry or warm nose means a dog is sick.

Dryness or discoloration of a dog's nose doesn't necessarily mean a dog is sick. A dog's nose actually naturally dries out in its sleep, but is right back to normal about 10 minutes after it wakes up. Dryness can also be due to allergies, sunburn, or dehydration, and some dogs' noses tend to get dryer as they age.

5. Indoor dogs don't get heartworm.

Just because a dog stays indoors most of the time doesn't mean it can't come into contact with a mosquito. And it takes just one mosquito bite for a dog to contract heartworm, which can be fatal. At the very least, the treatment process will be expensive to the pet owner. Heartworm prevention is important for both indoor and outdoor dogs.

6. Only male dogs hump.

Mounting, or humping, is a sign of both dominance and insecurity and can be performed by either a male or female dog. Some dogs hump when they become excited or stressed by a situation. A female dog may even hump to get attention.

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
