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.

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.
