Think you know all there is to know about canines? Think again! Here are some fun facts about dogs to better get to know your favorite pet pal.

  1. Dog tongues form into a cup to drink water. This allows them to get more water in each lick.
  2. In ancient Greece, spiked dog collars were created to protect canines’ throats from wolf attacks.
  3. The wetness of a dog’s nose helps it determine which direction a smell originates.
  4. Seeing-eye dogs go to the bathroom on command so their pet-parents know to clean it up. Male dogs are even trained to not lift their leg while doing their business!
  5. This one is not our favorite. Apparently dogs aren’t the biggest fans of human hugs. Canines interpret putting a limb over another animal as a sign of dominance.
  6. Dogs can see in color! Just not as vividly as humans. Dogs only have two cones in their eyes to detect colors, while humans have three. So dogs see colors on a blue and yellow scale but can’t distinguish between red and green. However, they definitely have better night vision than humans
  7. Dogs can smell disease. Research has proven that dogs have an amazing ability to recognize the smell of a range of organic compounds that show the human body isn’t working as it should. So your dog could actually diagnose cancer, diabetes, and even the early signs of an epileptic seizure.
  8. Dogs dream, but not all dogs dream the same amount. Small dogs dream more than big dogs! For example, a toy poodle may dream once every 10 minutes, while a great dane may have a dream once an hour.
  9. Dogs have three eyelids in order to help keep their eyes moist and protected. They have an upper lid, lower lid, and a nictitating membrane.
  10. While humans sweat all over their bodies, dogs only sweat through the pads of their feet.
