The 50 Fun Dog Facts
1. All Dogs Are Directly Descended from Wolves
So we know that dogs are relatives of wolves, but did you know that every dog is a direct descendant of wolves? Many breeds show a striking resemblance to their wolf ancestors, such as the Siberian Husky, the Alaskan Malamute, and the German Shepherd.

3. A Dog’s Nose Is Its Fingerprint
No two dogs have the same nose. Each has a unique pattern to the individual, making a dog’s nose equivalent to a human’s fingerprint.
4. Puppies Are Born Deaf and Blind
Newborn puppies are still in a developmental stage when they are born. Both their ear canals and eyes are still closed at the time of their birth. During this time, they use heat sensors in their nose to detect their mother. The majority of puppies will begin opening their eyes and becoming responsive around 2 weeks of age.

Dogs pant when they become overheated, but did you know that their sense of smell is reduced by approximately 40% when he’s overheated and panting? It’s true!

7. Dogs Can Detect Disease in Humans
Speaking of a dog’s stellar nose, they can be trained to detect diseases such as cancer and diabetes in humans. When detecting cancer, the dog is trained to sense the biochemical differences in the breath of those that have been diagnosed with the disease. Similarly, dogs can smell the fluctuations in blood sugar in diabetics by smelling a human’s breath.
8. Dogs Aren’t Colorblind
Dogs are not colorblind like most people think. They can see blue and yellow vividly but do have trouble distinguishing between different shades of green and red, causing those colors to look more like grays and browns.
9. Dogs Have Fewer Taste Buds Than Humans
Dogs have about 1,700 taste buds, while humans have between 2,000–10,000. Maybe that’s why we like to enjoy a variety of cuisine and our canine counterparts are doing well just eating dry kibble. Dogs rely on their scent to entice them at mealtime. They enjoy the aroma more so than the taste of their food.
10. Dogs Are as Smart as 2-Year-Old Children
Stanley Coren, a canine researcher, has been able to determine that your dog is just as smart as a 2-year-old child. Intelligence does depend on the breed. Border Collies are considered the most intelligent dog breed. Golden Retrievers and German Shepherds are pretty high up on the list as well.
11. Roughly 45% of Dogs in the United States Sleep in Their Owner’s Bed
It’s something we may try to avoid, but our furry friends have a way of making it into our hearts and our beds.
