Walking partner sidelined

So a couple months ago my girl Remy (who just turned 4) dislocated her rear leg hock/dog ankle bone. The vet was able to put the bone back into joint and she was put on restricted mobility for several weeks after which we were given the okay to start up short walks again. Last week she was limping more and holding up her paw so I took her back to the vet. Luckily the bone is still in place but the vet said no walks for 3-4 more weeks.

We usually walk together a couple miles a day in all weather (longer on the weekends) so we're both pretty bummed. Anyone else out there ever have a dog with a similar injury? Vet says she may have issues with that leg now for the rest of her life.
