I have a 17 month old lab mix pup who broke his back hind leg very severely. The vet put a pin in the femur and he did very well with surgery--this happened the last week of May. He is a VERY active dog and he refractured part of the femur four weeks ago. He was at the vet on crate rest while we were on vacation for 3 weeks. We have had him home for two weeks with a schedule for "rehab" of waking and house rest--no playing,running, or jumping. (difficult!!) He has done well with that, but he still puts no weight on the leg--only "toes" and it seems that the leg is misshapen. The vet told us he may need to have his leg amputated if it doesn't heal well. We are very concerned that this will happen. He just lets the leg hang now and most of the time walks on three legs. We don't know if we are expecting too much too soon with the leg in getting the muscle back or if the injury was just too bad to heal. I would appreciate hearing from anyone with any experience in this type of injury. We are taking him back to the vet on Monday, if possible. He has an appointment Aug. 20 for xrays and she was expecting him to be "back to normal" by then. Doesn't look to me like it is going to happen. He is such a sweet boy--we just want him to get better and if that means three legs, we'll deal with that, but we hope it doesn't.
