Long story short...my 8 year old lab/chow mix with a bad hip 'played' for 2 hours with a 3 year old 100+lb PitBull Now, she cant get up. When she was brought home at 5:30, she laid down and just now (8:30) attempted to get up to eat. She whimpered and it was a struggle. Her back end wobbled a few times before she could get her steady. She ate and laid back down. I thought I should get her to move around a bit and tried to get her to stand again...nope. Not even for string cheese! So she is on her supercomfy well padded bed laying very very still. Is there anything OTC that I can give her tonight? I am 99.9% certain its just muscle issues, not bone or joint.
