Dogs are as smart as toddlers 

Studies have indicated that dogs are intelligent enough to understand up to 250 words and gestures, as well as numbers up to five and simple mathematical calculations. The average dog is as intelligent as a two-year-old child.

It’s a myth that dogs are colour blind, they can only see colours very faintly – as well as humans can during dusk

There’s a Beatles track just for dogs

Some stray dogs in Moscow have learned to use the city’s subway system in order to travel to busier areas in search of food scraps.

Dogs have powerful noses 

The canine sense of smell is incredibly powerful compared to humans, though does vary among breeds. While humans have around five million smelling cells, alsatians are believed to have around 220 million. Sniffing out almost anything is never much of a problem.

A dog’s nose is as unique as a human fingerprint, with no two being the same.

Dogs can smell illnesses

If you have a certain strain of cancer, diabetes or epilepsy, your dog might already know, as studies have shown that they can be trained to sniff out these illnesses. Scientists believe this could be due to dogs sniffing out abnormal proteins.

The eye of a dog consists of three lids: an upper, lower and a third lid, called a nictitating membrane or haw. This third lid is designed to keep the eye both moist and protected from foreign bodies.

A weaker sense of taste 

Dogs depend more on their strong sense of smell, rather than their sense of taste, to differentiate between types of food. In fact, humans have almost five times the amount of taste buds that dogs do, so it’s no wonder that dog food isn’t very appealing to us.

Dogs drink water by turning the underside of their tongue into a cup in order to scoop up liquid.

Dogs are some of the most diverse mammals on the planet

From the Bassett hound to the golden jackal, dogs show off an incredible diversity in body shape and size.

It showed that a collie skull is as different from a Pekingese as a cat skull is from a walrus, for instance.

Dogs have a weasel heritage

The evolution of modern-day dogs can be traced back around 40 million years to the weasel-like Miacis, an animal genus that lived in trees and dens. The miacis later evolved into the Tomarctus, believed to be a direct relation of the genus Canis, that includes wolves and dogs.
