Dogs are our friends, they do more for us than any other species.  Guide dogs for blind and deaf, bomb sniffing dogs, guard dogs, rescue dogs, drug finding dogs, police/army dogs, therapy dogs to help with the clinically depressed and sick kids, they even have dogs capable of detecting early stages of cancer and more, not to mention some who refuse to leave their owner's grave. We  honestly don't deserve them.  This is coming from a cat person. I can accept the answer by Sayyid Si
