Weakness of hindlegs in 9yo GSD
My GSD is around 8 or 9 yo. I noticed that she is slow to sit, slow to get up and cannot jump into the back of the jeep without assistance. I just adopted her 2 months ago so I cant say if this is something that has developed recently or if she has always had weak back legs. I am just curious if anyone else has experience with this...is it just a normal weakness due to being senior? I asked the vet and he said its just arthritis, but when she trots her hips sway alot more then other dogs. She takes Glucosomine now but I am wondering what to expect as the months and years progress. Does anyone else have experience with GSD weakness in hind legs?
