Dexter is a dog from Colorado, USA, who learned to walk on two legs like humans do after suffering a run over that left both of his front legs useless. When he was only one year old, he was hit by a car. The wheel of the vehicle crushed his front legs and they were practically useless. Everything was against him, but his owners had recently had to euthanize two dogs and decided to give him a chance to get ahead. After months of therapy and a lot of patience, the animal has managed to walk with its owner through the streets of Colorado like another person, leaning on its two hind legs and drawing a smile from the neighbors.
