Which animal is the modern canine a direct ancestor of?

If you guessed wolf, that is correct! More specifically, dogs are a direct descendant of the gray wolf (canis lupus), notes PBS.org. In addition to behavior shifts that occurred during domestication, our modern-day dogs are also smaller and generally have shorter muzzles and fewer teeth compared to their ancestors.

The frontal lobe of the canine brain has grown how much in the past 500 years? 1%, 5%, 10%, or no growth?

“The canine brain has had a frontal lobe growth of 5 percent in the last 500 years,” says Devereaux. This area of the brain is directly related to a dog’s ability to control their impulses, and while it has grown in the last 500 years, it’s still considered quite small.

True or false? A dog’s tail wags only when it is feeling happy

While we associate tail-wagging with a jovial pup (and this is often the case), this isn’t always true. How your dog’s tail wags is an indicator of its mood. For instance, if it wags to the right then they are happy, and if it wags to the left it could mean they’re frightened. A low wag indicates insecurity, and a rapid wag accompanied by tense muscles means they’re in an aggressive, ready-to-attack state. Learn more about how to decode your dog’s tail-wag.

Do dogs have more or fewer teeth compared to humans?

Dogs have more teeth than humans. While humans have a total of 32 teeth, the average canine mouth has a total of 42 teeth, says Devereaux. Their teeth are used “for ripping, tearing and shredding their prey.” Here’s how to stop a puppy from biting, according to dog trainers.

True or false? Dogs can eat onions

Though onions can enhance many meals for us humans, this food is strictly off-limits to canines. When consumed by a dog, onions cause an upset stomach, and, worse, and can lead to red blood cell damage. This is also true for garlic and chives, as well as a handful of otherwise unassuming human foods that are toxic to dogs.

Bacteria in a dog’s mouth is directly related to which internal organ?

If you guess heart, then you’re correct! A dog’s oral health is directly related to their cardiovascular health, just like ours, notes Devereaux. This is all the more reason to make sure you’re keeping up on your pup’s dental hygiene, which includes regular brushing and periodic professional cleanings by your vet.

True or False? Dogs are colorblind

The answer depends on your definition of colorblind. Dogs can technically see in color, but they’re limited to a blue and yellow spectrum, says the AKC. Don’t feel too bad for them, though.
