We all love our dogs, so why wouldn’t we want to learn more about them? There are so many interesting facts about a man’s best friend that most people don’t know. We’ve put together a list of 50 of the most fascinating and fun dog facts, many of which you’ve probably never heard of before.


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. It’s interesting to know that breeds like the Pug, Pekingese, and Chihuahua are also direct descendants.

2. There Are Over 75 Million Pet Dogs in the United States

Recent studies show that there are at least 75.8 million pet dogs in the United States currently. This is more than in any other country in the world.

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.

5. A Dog’s Sense of Smell Is Reduced When Panting

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!

6. Dogs Have Stellar Noses

The human nose contains about 5 million receptors. If you think that is a lot, dogs have as many as 300 million receptors. Human beings can’t even begin to imagine what it’s like to have the sense of smell of our canine friends.

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. Forty-five percent is a pretty large number considering the number of pet dogs in the United States. So, either we truly enjoy sharing our bed with the extra body or we are just easy to guilt!

12. Dogs Can Learn More Than 1,000 Words

Some major Universities like Duke University and Yale University have programs dedicated to dog psychology. We have thus far learned that your dog has a pretty impressive vocabulary. They may not be able to speak back to you, but they pick up on quite a bit of what you’re saying! If only they could just talk back!

13. Dogs Sleep Curled in a Ball Out of Instinct

It’s so cute watching your dog curl up in a tight ball and sleep. Come to find out, this is out of instinct. They do this to protect their vital organs while they are asleep. They also do this to keep their body heat retained and stay warm.

20. Chocolate Can Be Fatal to a Dog

It’s pretty basic information to know that dogs shouldn’t eat chocolate. The real reasoning behind this is that chocolate is potentially deadly to dogs. Chocolate contains theobromine, a substance that dogs cannot metabolize. Consumption of chocolate, especially pure dark chocolate, can cause toxicity in their body that can lead to death. If your dog ingests chocolate, it’s always best to consult your veterinarian.

22. Dogs Learn About Each Other Through Butt Sniffing

Dogs’ butts are home to glands that produce pheromones that give other dogs information about that individual such as sex, diet, and health. It’s a dog’s way of introducing themselves and getting to know one another. I guess we can be thankful it’s not the same for us humans.

Dogs tend to react much more to your tone than your words. While they can get to know a variety of words, they are much better at picking up on your overall tone. That’s why they may cower if you raise your voice or get excited when you speak in a high-pitched, happy tone.

24. Dogs Dream Just Like You and Me

It’s almost certain that you’ve noticed your dog twitching, barking, or even running in place as they sleep. Well, that’s because they can dream just like us humans.

Research also suggests that small dogs dream more than larger ones.
