Dog’s do not see in black and white, however, they are what most would consider to be color-blind. This means that dogs have two color receptors that are called “cones” whereas humans have three. Dogs have yellow-blue dichromatic visions which means that the vision of dogs are most similar to someone who has red-green color blindness.

This means that dogs are very good at distinguishing between different shades of blues and yellows, however, they wouldn’t be able to see shades of red or green very well or at all.

24. All puppies are born blind and deaf.

Dog Facts for Kids

All dogs are born blind and deaf.


At birth, a dog’s eyes are sealed shut and won’t open for approximately 2 weeks. Their hearing doesn’t develop until around the age of 6 weeks.

They are basically born helpful and the first sense that these furry babies develop is touch. Puppies can also be twins similarly to humans and are born with baby teeth. Their coat color can also change as they age and an estimated 1.2 million pups are born yearly.

23. The worldwide dog population is estimated to be over 700 million.

Much like humans, dogs find yawns to be contagious. If they see or hear another dog or person yawn, then they are likely to follow suit. Interestingly enough, the dog is four times as likely to yawn as well if they know the person who is yawning.

20. Dogs are as smart as toddlers.

While panting is the primary way for a dog to cool themselves, they are capable of sweating through the skin on both their noses and their paws.

Dogs pant as a way of evaporative cooling. This means that when a dog gets too hot, it will open its mouth and breathe heavy. As water tends to evaporate from the dog’s tongue, nose, and lungs, it helps to then lower the body temperature of the dog.

17. Dogs were domesticated from wild wolves.

Dog Facts for Kids

Modern day dogs are descendants of wolves that were domesticated.


Estimates vary, but some scientists believe that dogs were first domesticated from the wolf approximately 15,000 years ago. Early breeds were used to help hunt and as companion animals.
