They were hired to walk my dog and a friend's dog. However, when I came home in the evening I discoverd my dog had been drug on an abrassive surface like concrete. The owner denied anything...stating he said he only saw a little cut on his paw, but appeared ok. OK? My dog, a 10lb Chihuahua had both of his front pads worn away, his belly and chest were raw, his thighs and knees were torn up and so were the tops of his back feet. He was shaking and near shock when I returned home. The poor thing could not walk and because of his injuries I had a hard time carrying him. I am currently pursuing legal actions...dont take a chance with your pet if you love them... this guy is a monster.
