Is There a Difference Between Mutts and Mixed-Breed Dogs?

July 31 is National Mutt Day, a day to celebrate everything great about mutts. In 2005, animal welfare advocate Colleen Paige created the day, which is acknowledged once again on December 2 (because all those good boys and girls deserve two days of nonstop treats and belly rubs). But what exactly is a mutt? Is it the same as a mixed-breed dog? And how does it differ from other dog breeds?

First off: The fact that National Mutt Day is also referred to as National Mixed Breed Dog Day should tell you something—namely, that mutts and mixed-breeds are basically the same thing. Meaning that, as the latter name suggests, they are made up of more than one breed of dog.

Whereas purebred dogs have registration papers that confirm the dog's single-breed pedigree, mutts aren't registered and each of their parents could be a mix of several breeds themselves.

Where it gets a little confusing is when you come to designer or hybrid dogs, where two specific breeds are intentionally cross-bred in order to create a sort of sub-breed that mixes the best traits of both pups (like mating a poodle with a Labrador to get a Labradoodle). Though designer dogs are extremely popular, they're essentially just fancy mutts. While the American Kennel Club (AKC) does offer some activities for mixed-breed dogs to take part in, the organization only formally recognizes purebred dogs on its official registry (sorry Puggle lovers).

With so many different types of dog breeds, what are the benefits of adopting a mutt? According to the dog lovers behind National Mutt Day, approximately 80 percent of all shelter dogs are mixed breeds. That’s a lot of dogs—and a lot of dogs in need of forever homes! And there are plenty of benefits to adopting a dog versus purchasing one: first, adopting a dog is almost always cheaper than purchasing one from a (reputable) breeder. And because there are so many dogs in shelters, and only so much room to accommodate them, adopting a dog means that you're potentially saving one dog's life and making room for another dog to move in to the shelter. (Of the 3.3 million dogs that enter shelters each year, the ASPCA estimates that 670,000 of them are euthanized.)

And when you get your mutt home, the benefits continue. Though there's some debate over the topic, some experts have found that because mixed-breed pooches aren’t exposed to as many genetically inherited health issues, they can often be healthier. According to some statistics, mutts can also have a longer life expectancy. Mutts are great in work situations, too, like serving as guide and therapy dogs or sniffing out drugs and bombs. And in 2014, for the first time ever, The Westminster Kennel Club allowed mutts to compete in their annual dog show.

One downside to owning a mutt (if it can be considered a downside) is that if you don't know a dog's ancestry, you might have trouble predicting its temperament or unique behaviors. But many pet parents see this as one of the benefits of adopting a mixed-breed pupper: they're full of surprises and totally unique. (Plus, dog DNA tests are widely available, so if you really want to know what your dog is made of, it's easy to find out.)

What's the Difference Between Stuffing and Dressing?

For carbohydrate lovers, nothing completes a Thanksgiving meal quite like stuffing—shovelfuls of bread, celery, mushrooms, and other ingredients that complement all of that turkey protein.

Some people don’t say stuffing, though. They say dressing. In these calamitous times, knowing how to properly refer to the giant glob of insulin-spiking bread seems necessary. So what's the difference?

Let’s dismiss one theory off the bat: Dressing and stuffing do not correlate with how the side dish is prepared. A turkey can be stuffed with dressing, and stuffing can be served in a casserole dish. Whether it’s ever seen the inside of a bird is irrelevant, and anyone who tells you otherwise is wrong and should be met with suspicion, if not outright derision.

The terms are actually separated due to regional dialects. Dressing seems to be the favored descriptor for southern states like Mississippi, Tennessee, South Carolina, and Georgia, while stuffing is preferred by Maine, New York, and other northern areas. (Some parts of Pennsylvania call it filling, which is a bit too on the nose, but to each their own.)

If stuffing stemmed from the common practice of filling a turkey with carbs, why the division? According to HuffPost, it may have been because Southerners considered the word stuffing impolite, and therefore never embraced it.

While you should experience no material difference in asking for stuffing or dressing, when visiting relatives it might be helpful to keep to their regionally-preferred word to avoid confusion. Enjoy stuffing yourselves.

Why Do Tires Have to Be Filled With Air?

Paul Misencik:

This is an issue that has perplexed me for most of my life, because pneumatic tires filled with air seem like the last anachronistic, 19th-century component of a modern automobile, and an idea which should have disappeared many decades ago. In an era where even the internal combustion engine itself is giving way to electric motors, and where a new economy hatchback has exponentially more computing power than the Space Shuttle, pneumatic tires don’t seem to make sense any longer.

(And before I get flamed, I know modern tires are vastly more advanced and reliable and capable than their 1930s counterparts. Blowouts, which were a common occurrence when I was a kid, are pretty much unheard of today. Modern tires are great, but they are still vulnerable and maintenance-intensive in a way that doesn’t make any sense to me.)

Companies have experimented with non-pneumatic passenger vehicle tires in the modern age—one of the primary drivers was Michelin. But the tires weren’t filled with solid rubber. In fact, they didn’t even have sidewalls. They were open on the sides, and they had a support lattice of structural polyester ribs, with a ton of air space between the contact patch and the (now deformable) wheel.

One of the big problems with switching from pneumatic tires to non-pneumatic tires is the fact that the current air-filled tire is an important component of the suspension of a vehicle. The flex in the sidewall is a critical part of the compliance of the suspension and substantially affects a vehicle's ride and handling. (Which is why race car drivers sweat tire pressures at each corner of the vehicle so much, as even a small change in tire pressure can have a big effect on the handling and grip of a vehicle.)

If a company like Michelin wants to make a non-pneumatic tire, they'll improve their chances of finding success with it if the new design mimics the compliance and flex characteristics of the outgoing, air-filled models as closely as possible. That way, Michelin would be able to sell the new, non-pneumatic design as a retrofit to older vehicles whose suspensions were originally designed with pneumatic tires in mind. And that is hugely important because if they can’t, it becomes much more difficult to convince manufacturers to change over to the new design—particularly after the mild debacle of Michelin’s failed “TRX” metric tire idea of the 1980s, which required the use of a special wheel and which, despite being by most accounts a superior design in almost every way, never really took off. (Owners of 1980s Ferrari 512 Berlinetta Boxers and some Saab 900 turbos will know what I’m talking about here.)

Non-pneumatic Michelin tires are also rather weird looking, and it’s not clear which manufacturers, if any, would take the risk of being the first to offer them on a new car.

So that is the real issue: Any non-pneumatic tire design must be not only clearly superior to the pneumatic designs of the past, but it must be functionally identical to the outgoing models they would replace, and they must be visually acceptable to consumers.

I hope it happens, though. I hope someone cracks the nut. Pneumatic tires are a 19th-century application still being used on 21st-century vehicles, and at some point that needs to change.
