13 Surprising Dog Facts

Dog knowledge goes far beyond understanding what to feed them and how to care for them.

Our canine friends have storied histories and fascinating biologies that make for some truly astounding trivia.

These incredible dog facts will demonstrate just how much there is to know (and love!) about your pup and all those who came before him.

Dog History and Biology Facts

1. Dogs and Wolves Diverged More than 20,000 Years Ago….

Your dog may resemble a wolf in many ways, but it’s been a very long time since the two were the same species: between 20,000 and 40,000 years.

2. …And Domestication Occurred Around the Same Time

Though we don’t know exactly when humans domesticated dogs, genetic sequencing and archaeological studies suggest that it occurred around 23,500 years ago.

The coinciding of these timelines suggests that domestication may be what prompted the dog and wolf to diverge. Humans may be directly responsible for the creation of the dog species!

3. The First Dog Breed Was the Saluki

As far back as 7000 BC, Egyptian pharaohs, Greek kings and other ancient royalty championed the Saluki.

It’s easy to see why: the Saluki is fast, agile, adaptable, gentle, and beautiful. And as the 120th most popular dog breed, it’s clearly still got a lot of love today — 9,000 years after its first appearance.

4. A Dog’s Nose Contains 300 Million Scent Receptors

The human nose contains around 6 million scent receptors. That sounds like a lot… until you find out that your dog’s nose contains 300 million receptors.

And dogs devote 40 times more brainpower to processing smell than we do.

Effectively, this makes dogs 10,000 to 100,000 times better at smelling than humans. Dog researcher Alexandra Horowitz puts it this way: a dog could sniff out a teaspoon of sugar in a million gallons of water!

5. Dogs Can Hear Earthquakes Hours — Or Even Days — Before They Occur

While researching seasonal affective disorder in dogs, Dr. Stanley Coren made a fascinating accidental discovery: nearly 50% of dogs showed extreme agitation and anxiety the day before a major earthquake.

But all but one of the hearing-impaired dogs in the study did not display increased agitation. And dogs with floppy ears that blocked more sound were less agitated than dogs without floppy ears.

This suggests that the dogs could hear the high-pitched underground movements of the earth long before we could detect them. They can hear frequencies up to 60,000 Hz (we max out at 20,000 Hz), which encompasses the frequencies produced by shallow tectonic plate activity.

6. Dogs Poop in Alignment with the Earth’s Magnetic Field

Ever wonder why your dog takes forever to find a spot to poop?

It’s because he’s got to orient himself with the Earth’s magnetic field.

A 2013 study showed that when the magnetic field is calm, dogs align their bodies along the north-south axis before doing their business. But when the magnetic field is unstable, the behavior stops.

It’s not clear why dogs do this, but think of it this way: you’ve got a canine companion and a compass all in one package!

7. Dogs Can Learn Hundreds (Or Thousands!) of Words

The average dog understands around 165 words, but that’s by no means the upper limit.

For proof, look no further than Chaser the Border collie, who knows 1,022 words and can associate them with objects with over 90% accuracy.

This puts Chaser’s vocabulary on par with a 3 year old human’s. And with enough training and attention, such a large vocabulary could be within your dog’s abilities too!

8. One Pair of Unaltered Dogs Can Produce 67,000 New Dogs in 6 Years

Assuming that none of their puppies (or grand-puppies, or great grand-puppies, etc.) are fixed, one pair of dogs can be responsible for bringing 67,000 new puppies into the world over just 6 years.

Dogs can breed so quickly and at such young ages that spaying and neutering is necessary to avoid this staggering population growth.

9. The Top 10 Dog Names Are All Human Names

Perhaps it’s a sign of how strongly we perceive our dogs as family members: all of 2019’s top 10 dog names are human names.

Spot and Rover will need to move over and make room for Bella, Charlie, Luna, Lucy and Max — the top 5 names. Rounding out the top 10 are Bailey, Cooper, Daisy, Sadie and Molly.

Classroom roll call or dog boarding kennel roster? With names like these, it’s tough to tell the difference!

10. Kublai Khan Holds the Record for Most Dogs Owned: 5,000!

13th-century Mongolian Emperor Kublai Khan must have been a huge dog lover, because he owned a jaw-dropping 5,000+ of them — mostly Mastiffs, but also Tibetan Spaniels.

The dogs had their own caretaking staff and frequently went on hunting trips, accompanying the Emperor’s 10,000 men to hunt bears, deer and other animals.

11. 12 Dogs Were Aboard the Titanic — and 3 Survived

The Titanic’s luxurious dog kennels appealed to pet owners, 12 of whom brought their dogs along on the ship’s maiden (and final) voyage.

But after the ship crashed into an iceberg, only 3 made it to safety: a Pomeranian named Lady, a Pekingese named Sun Yat Sen and another Pomeranian whose name remains unknown.

12. The World’s Oldest Dog Lived to Be 29 Years Old

The average lifespan of a dog is 10 to 13 years, but a few individuals have managed to nearly triple that.

Bluey, an Australian Cattle Dog, holds the world record for longest verified lifespan: an astonishing 29 years and 5 months.

13. Zeus, the World’s Tallest Dog, Was Over 7 Feet Tall When Standing

A Great Dane named Zeus holds the world record for tallest dog. He measured 3 feet 8 inches at the shoulder, but reached a whopping 7 feet 4 inches when standing on his hind legs.

That’s 3 inches taller than Shaq and only 3 inches shorter than Gheorghe Mureșan, the tallest player in NBA history.

Zeus weighed 155 pounds and ate 30 pounds of food every 2 weeks. Unfortunately, his large size took a toll on his organs and he passed away at just 5 years old in 2014.
