Stretching hind legs
I have a 3 year old gsd female. Her and I go for a walk almost everyday about 4 miles. This was approved by the vet. She is on Cosequin DS for maintenance. Past few days she seems to be stretching her hind legs alot. Also when she is coming out of the crate her back legs seem stiff for a moment and then she appears to be fine. I check her pads etc no signs of pain. Anyone else with this happening with their gsd.
Any advise is appreciated.
