Just got off the phone with the vet and he is thinking my GSP might have it. It started about 3 weeks ago she was favoring her back leg. I brushed it off as nothing and let her rest for a couple days and she was better. Now tonight same thing but with her front leg. Have a appointment first thing in the morning. Anyone have any experience with this. My kids are scared she is not going to be ok. Both of them fell asleep using the dog as a pillow tonight.
