Thank you everyone. Tonight she is not limping as bad as last night. But I've talked to my mom and she said she'd take her back. We both agreed it was too soon. I did need to get her to the vet for vaccines anyway though. So that is done.
Bruce and I had a discussion tonight as well. He wanted to know if they took x-rays while she is sedated would they be able to get a more definitive answer. I talked to the vet and she said they were sure it was a torn ACL. The radiologist said what he saw was compatible with that of an ACL tear. The vet said the only reason you'd need an xray now is to proceed with surgery. She suggested we do a consult with a surgeon. I need to discuss this with Bruce. I really want to give it another try at my moms.
