Our 4.5 year old Golden Retriever recently had sudden immobility in her back legs. We were visiting friends and had her tied to her stake outside. I went out to work on some stuff and she was jumping around trying to play with me, but I didn't have time. 2 hours later I went out to play with her and she couldn't even stand up. In the course of a few hours she went from totally normal to mysteriously crippled.
After we got back into town a few days later, we took her to the vet but she had sort of gradually improved since then and the vet couldn't find anything wrong.
After a few more days she started to get worse again. Not as bad as originally, but still taking a very long time to stand up, stiff slow walking, lethargic, and low appetite. We took her to the vet again and got anti-inflammatory meds for her.
These helped a little, but not much, so within a week, she was back at the vet getting Xrays and a full blood panel. Both came back inconclusive (vet couldn't find anything wrong), so the results are being sent to a specialist.
We've now spent over $600 on three vet visits and we still don't even know what is wrong. Has anyone experienced anything like this before? I've looked up other rear leg issues but this doesn't seem to fit most of them––especially with the extremely sudden (within a few hours) onset.
Any help would be appreciated. We can't afford to keep paying the vet for nothing.
