Dogs have the same levels of intelligence as 2-year-old children, a new study claims.
Scientists at the University of British Columbia have discovered that canines are able to understand up to 250 words, count up to five and solve "complex problems".
According to research leader Dr Stanley Coren, man's best friend can also deceive owners and other dogs to win treats, understand sign language and spot mathematical errors.
He is quoted by the Daily Express as saying: "The average dog is about as bright linguistically as a human 2-year-old. Obviously we are not going to sit down and have a conversation with a dog, but like a 2-year-old, they show that they can understand words and gestures."
Coren added that dogs have domestication to thank for their growing brainpower.
He commented: "When a human points, the wolf will look at the finger, while the dog will look where the finger is pointing."
Meanwhile, border collies have been named as the most intelligent pooches, followed by poodles, German shepherds and golden retrievers.
