Most people think that dogs only care of on time walks and eating, but everything is not that primitive and simple, dogs have much more interesting ideas in their heads. According to the recent surveys it turned out that dogs are capable of understanding up to 250 words and some basic maths.

Some dogs can be brighter than children. They can understand some words and gestures, count up to five and even enjoy some simple arithmetic. So, some dogs can be cleverer than a two-year-old child.

However, not all dogs are the same, for example, border collies are among the cleverest dogs ever, they DO top the list. A lot of scientists claim that an average dog is about as bright as a human two year-old.

There is a list of the smartest dogs ever!
