My dog is about 7 months old and about 70 lbs. Yesterday night I noticed his elbow is really swollen. It feels as though it is filled with fluid. I have read about Bursas, and that sounds about accurate...but he doesnt spend prolonged time on hard surfaces. He sleeps inside on the carpet and has a blanket in his kennel for the short time he has to stay in it when I am not home. I am probably going to take him to the vet if it doesnt clear up soon, but I was just wondering what you all thought...
