I need help with a dog that was given to us from my DH's boss. He's a yorkie and his name is Cassidy. Well I just noticed that he has this red spot on his back by his tail and it looks really painful. I'm pretty sure he was an inside dog. Here is a pic. I hope its nothing major I bought him a spray that helps with the itch but he just keeps licking at it.
Sorry if the pic is big.
