So sorry that Rab is having problems. I hope it turns out to not be serious. ***pats for Rab, chocolate for you and hugs for you all.***
My 13 pound, 13+ year old, pain in the butt mini Schnauzer started limping and having trouble going up stairs. Turns out he had inflammation in his hip joint. He gets glucosamine, chondroiton and MSM in his food and 1 baby aspirin twice a day. It helps, but he is old.
