Hi,
Thanks for your good wishes!
Jack was very wobbly and grumpy after the anaesthetic, but has recovered his good humour now.
They can't find anything wrong with his hip, but he still stands awkwardly. When he walks or runs, all fine. I got him from Many Tears who said that their vet thought he might have been dropped as a pup.
Our other rescue Tia had much worse problems when we took her on, so he's not so bad.
Cheers,
