The vet did the x-rays and nothing in his bones/joints showed up. It's a soft tissue in there that's causing him to limp.
He's going in again next Tuesday for a minor sirjury. They're going to do a biopsy for the tissue in there.
And to add to that, it'll take 10 days to recover; we have to drop out of his advance obedience classes since he won't be able to do the jumping and retrieving.
Worst of all, it's going to cost roughly $400 for this minor surgury. I have no idea how we're going to pay for this but pray that everything goes alright! I was worried to death today and it was only x-rays! Imagine what a nutcase I'll be next week!
