3 Amazing Facts About Dogs!


[Intro] This is Louie. He’s a hound. This is Auzzy. He’s an Australian cattle
dog. And this is Abby. She’s a corgi. They look pretty different, but they’re
all examples of humans’ very first pets — dogs! Even if you have a dog of your own, I bet
you don’t know some of these amazing things about our furry best friends. For example! Did you know that all dogs are
related to wolves? That’s right! This is related to this. Remember how I said dogs were human’s first
pets? Well, about 15,000 years ago, humans lived
alongside wolves. And in time, some of these wolves became domesticated, meaning that they
changed from being wild, to being able to live and even work closely with humans. So, over thousands of years, some of those
wolves became the domesticated dogs we know and love! Wild wolves still live in many places in the
world today. But there are also more than 400 different breeds of dogs! And all of the wolves and dogs on Earth are
thought to have descended from the same animal: a predator that roamed our planet millions
of years ago. Scientists called it Eucyon davisi, and it
looked a lot like today’s wolves, with one major difference: It was probably a lot bigger. So if all wolves and dogs descended from this
early predator, that means wolves and dogs are related! Dogs are also related to other animals that
look a lot like them — including foxes, jackals, and coyotes. Together with wolves, these meat-eating mammals
are called canines. That’s one big furry family! Now, another cool thing about dogs? They’re
super-smellers! Their sensitive noses have 40 times more cells
in them for smelling than ours do — plus they have the ability to wiggle their noses
in ways that we can’t! And that’s not just a neat trick—by wiggling
each nostril separately, dogs can figure out which direction a smell is coming from. So, when they’re born, puppies can’t hear
or see anything, but they quickly learn to find their mom—and other important things
in the world around them—just by using their sense of smell. Dogs also use their smelling skills when they
meet new dog friends. Instead of shaking paws or barking to say
hello, dogs sniff each other’s butts! Dogs don’t recognize each other by name,
or even by looks; they identify other dogs by how they smell. That’s where they sniff, because all dogs
have special scent glands on their rears, and dogs use those scents to learn about each
other! By sniffing, a dog can tell if another pup
is young or old, a boy or a girl, if he’s sick or healthy, and even what kind of mood
he’s in! Not all dog sniffing involves butts, though. Lots of dogs put their powerful sense of smell
to use in other ways: Some dogs can sniff out and rescue people who are lost, some hunt
for escaped criminals, and a few are even being trained to sniff out deadly diseases. That’s awesome! Super dogs to the rescue! And lastly, our third cool thing about dogs:
Some of them can remember more words than a baby person. Even though they can’t talk, dogs make great
listeners. Most of them can understand about 165 words—way
more than just “sit,” or “stay.” And some can remember even more than that. One border collie was trained to understand
over a thousand spoken words–and she learned those words as quickly as a small child would. So, dogs are smart! Now, whenever you see a pooch — whether it
looks like Abby, Auzzy, Louie, or someone completely different — you’ll know that
you’re looking at a really smart relative of wild wolves with a super sense of smell! If you’d like us to sniff out more information
