Dogs can read your face.

Scientists have shown that, out of the entire animal kingdom, dogs are the only animals that can read the emotions on our faces like other humans do. Dogs can tell at a glance if we’re joyful, confused, angry, or sad, just by looking at our faces. They also can be affected by these emotions, often feeling them just as strongly as we do. 

Check out these dogs’ cute manners here.

Dogs sweat through their paws.
What? Dogs sweat? Sure they do! Though, instead of sweating through their skin like people, they sweat through their paws. Check it out the next time the temperature rises and your dog seems a little hot. This is one of the reasons why many dogs’ feet smell salty, like popcorn or corn chips!
Dogs’ nose-prints are just as unique as fingerprints are to humans.
Just as humans can be identified absolutely by their fingerprints, dogs can be identified by their nose prints. Police have even used the fact that each individual dog has a unique nose print to solve crimes, proving that they, or their owners, were present at a crime scene. 
There are plenty of wealthy dogs.
Treated like members of the family, pets are increasingly included in their owners’ wills, often much to the dismay of human relatives who find themselves snubbed in favor of the deceased’s four-legged best friend. It is estimated that, in the United States, over one million dogs are currently the primary beneficiaries of their owner’s wills.
Dogs can learn impressive vocabularies.
The average dog is as intelligent as a human toddler and can easily learn vocabularies of 200 to 500 words. Dogs are also capable of understanding basic math skills, like counting and sequencing.
Greyhounds hold two honors.
Not only is the Greyhound the fastest dog in the world, with the ability to reach speeds of up to 45 miles per hour; it is also the only breed of dog mentioned in the Bible.  The reference can be found in Proverbs 30:31.
Dogs are hotter than humans.
A dog’s average temperature is  101 to 103 degrees Fahrenheit. Fleas and ticks are attracted to heat, which is why they wind up attached to dogs rather than humans.
Pit Bull is not a breed.
The Pit Bull is, without a doubt, the most misunderstood dog breed. In fact, one of the most misunderstood things about it is that it’s not really a dog breed at all.

The sound of rain hurts dogs’ ears.
Dogs don’t balk at going outside in the rain to do their business for fear of getting wet. Rain amplifies sounds and hurts their sensitive ears.
Dogs can detect cancer and other diseases.
If you have cancer, diabetes, or epilepsy, your dog might be the first to know. Studies have shown that dogs can be trained to sniff out cancers of the lung, breast, skin, bladder, and prostate. Researchers suspect the canines are picking up on extraordinarily faint scents given off by the abnormal cells.
A dog’s sense of smell is more than 100,000 times stronger than a humans.
While humans have about five million scent receptors in their noses, a bloodhound has up to three hundred million in his. There’s no hiding any bones from him!
