Our Jack Russell Terrier (Flo) had her left hind-leg amputated yesterday?

I worked as a vet tech. You would be so surprised at how quickly animals heal! Your pup will be just fine. I've seen these dogs hop along like they never had the leg at all. A wonderful thing. Wish all us humans could recover like that. Good luck and don't baby her to much. She's going to be just fine.
