Hi my 8 year old almost 9 year old male gsd has perianal fistuals for at least 3 years now. he had to have suitures twice to repair bleeding. In the past month he has started to stumble around and his legs seem to be getting progressively weeker in the past week. My vet said it is nerve damage because of the way he curls his toes and put him on a human pill not nurton(sp) but similiar. Over the past 24 hours he has gotten much worse and I have noticed he has raw spots from draging himself. My vet said we could get a carrier and carry him around and surgery might work. But we have to travel 100 miles and it will cost serval thousand dollars. I need some advice I am afraid if I wait any long my only option will be to put him asleep. Please help!
