You probably think of your dog as part of the family, but sometimes your canine companion does the most peculiar things. Here are the answers to some of the questions you’ve been pondering about your pet.

15. DO DOGS GET JEALOUS?

Anyone with two dogs will probably tell you that dogs definitely feel jealousy—and it’s true! A 2014 study confirmed that your pet gets a little miffed when you start petting other dogs on the side.

Subjects in the study were asked to give love and attention to objects while filming their dog’s reactions. The items were a stuffed dog, a jack-o-lantern, and a pop-up book. The participants would give attention to the plush and pumpkin, and then read from the book. Scientists recorded the reactions of the dogs and looked for jealous signs such as pushing the owner or snapping. The study found that dogs displayed many jealous tendencies and made attempts to break the owner away from the rival. They were most threatened by the stuffed dog and least threatened by the book.

14. WHY IS MY DOG’S NOSE ALWAYS WET?

A common misconception is that your dog’s wet nose is a sign of good health. In reality, the moisture on Fido’s nose is no indication of their overall well-being. The reason for a dog’s wet nose is a little murkier. One explanation is that dogs repeatedly lick their nose throughout the day to keep it clean. Another is that the moisture helps them cool off. Dogs don’t sweat the way humans do, so they pant and let off extra heat through their noses. A special gland in the nose produces a clear fluid that helps them cool down faster.

13. HOW MUCH BETTER IS A DOG’S SENSE OF SMELL THAN OUR OWN?

A dog can smell anywhere from 10,000 to 100,000 times better than the average human. Canines have 300 million olfactory receptors, compared to our measly six million. Moreover, the part of the brain dedicated to smell is 40 times larger in dogs than in humans.

A dog’s nose also works differently than the human nose. While people breathe in and out the same way, canines breathe in through their nostrils and out through the slits found on the sides of the nose. This system circulates air so that the animal is always bringing in new smells. Breeds like the bloodhound also have the advantage of floppy ears that push up new smells.
