I have a 13 yr old border collie. She has exhibited a hip problem and is in quite a bit of pain after laying around. I have taken her to the veterinarian twice and they ran tests and blood tests and said they found nothing. The dog has lost about 20% to 30% of her body weight. Now she is shedding like crazy. I have combed her 3 times in about an hour and she still has clumps of fur dropping off of her. It really bothers me , but if the veterinarian can't find anything wrong what do I do?
