- Dogs can smell thousands of times better than humans. They have 125 million receptor while we have only 5 million.
- A dog’s nose is the equivalent of a human fingerprint, with each having a unique pattern of ridges and creases.
- Dogs dream like people.
- Dogs are as smart as a two-year-old baby. Man’s best friend can count, understand over 150 words, and even trick people or other dogs to get treats. Intelligence varies based on breed—Border collies are the smartest.
- Dogs only mate twice a year.
- Tail wagging has its own language. 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.
- Puppies are born blind and deaf. Most puppies open their eyes and respond to noises after about two weeks.
- Dogs have a “sixth sense.” In a 2010 poll, 67 percent of pet owners reported their pets acting strangely right before a storm, and 43 percent 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.
- Dogs only have sweat glands in their paws. Even though they sweat out through the pads of their paws, their main form of cooling down is panting.
- Your dog’s feet might smell like corn. Some pet owners might notice the faint scent of corn chips or popcorn lingering around their dog. This is called “frito feet,” and it happens when sweat and bacteria builds up in the paws.
- “Dog breath” is actually unhealthy. You might expect your dog’s mouth to smell like, well, dog. But persistent bad breath can actually be a sign of dental disease or other health problems. If you don’t already, have your dog’s teeth examined by a veterinarian every year.
- It’s not abnormal for dogs to eat feces. It’s no secret: dogs often eat their own feces (and other fecal matter). But though it might seem gross, the ASPCA says it’s perfectly normal, stemming from their pre-domestication days thousands of years ago. More common in puppies, older dogs usually grow out of it, although some do it into adulthood.
- Your dog does have a sense of time — and misses you when you’re gone.
If you think your dog knows when it’s time for dinner or a walk, you’re right! Dogs pick up on our routines and habits, and they also sense how much time has passed. One study showed how dogs responded differently to their owners being gone for different lengths of time.
- Your one year-old pup is as physically mature as a 15-year-old human.
Large dogs age faster than small ones. You can get a more exact comparison for your dog using this nifty Dog Age Calculator.
- Dogs can hear 4 times as far as humans. Puppies may be born deaf, but they quickly surpass our hearing abilities. Dogs can also hear higher pitched sounds, detecting a frequency range of 67 to 45,000 hertz (cycles per second). The human range is from 64 to 23,000 hertz. In both dogs and humans, the upper end of hearing range decreases with age.
