My dog, Mister Banks, is an eleven year old bichon shih tzu mix I purchased from Alberta when he was only ten weeks old. Today, I discovered a strange hairless patch on his left thigh where you can see a small thin bit of hair and his skin underneath. His skin looks as it usually is. But his coat is fairly thick (I am going to get him groomed on Thursday) and it’s just this one area. It is about seven centimetres long and four wide. His skin is level with the rest of his body, so it’s not lumpy or anything. But when I scratch him in this paticular area, he will start kicking his leg. I just noticed as I was typing this that he is chewing on the area. I just gave him a flea bath so I don’t think it is fleas. He is acting normally and shows no signs of sickness. Does anybody know what this could be or if I should get it checked out professionaly?
