I should have searched for this before posting because I am sure I am not the only one with a dog that chases his tail. I am not sure how to get him to stop, or why he does it. He is very fast at it though I tell ya. It makes me dizzy just watching him. Because of his spinning as I call it, he has hurt his paw 3 times now. Soft tissue injuries. In order to get him to stop I have to yell at him....(2 minutes later you will hear me say sorry though. I can't stay mad at him)this does stop him for about 5 minutes. I am wondering if it is because he was taken so young from his parents. Any thoughts. ???
