<b>The “smell” center of a dog’s brain is 40 times larger than yours.</b>

Dogs can smell thousands of times better than humans. Their noses have millions more scent receptors—for example, a human nose averages 5 million while a Dachshund’s has 125 million—making them useful in sniffing out drugs, finding people, locating explosives, and more.

<b>No two dog noses are the same.</b>

A dog’s nose is the equivalent of a human fingerprint, with each having a unique pattern of ridges and creases.

<b>Dogs are as smart as a two-year-old toddler.</b>

According to canine researchers, your 2 year old toddler and pup are about on par when it comes to brains. Dogs can count, understand over 150 words, and even trick people or other dogs in order to get treats. Intelligence varies based on breed—we believe Border collies are the smartest.

<b>Tail wagging has its own language.</b>

If your dog excitedly wags their tail, it means they’re happy to see you, right? Not necessarily. According to researchers, dogs wag their tails to the right when they’re happy and to the left when they’re frightened. Wagging low means they’re insecure; and rapid tail wagging accompanied by tense muscles or dilated pupils can signal aggression.

<b>Dogs have a “sixth sense.”</b>

Many pet owners reported their pets acting strangely right before a storm, and a significant percentage said their pets behaved oddly right before something bad happened. The top clues? Whining, erratic behavior, or trying to hide in a safe place. There are even reports that dogs can sense illnesses, like cancer.
