A friend has a slightly fat lab, 1 1/4 yr old, who is very active. She has no forum to ask on, so I’m asking for her here. We thought her dog had pano. It is in one front leg, lasts two weeks, and then returns in the same spot, same leg. I told her pano doesn’t come back to the same leg twice, but I don’t know what else would act exactly like pano. Her dog limps, groans when she gently squeezes the long bone. They are trying to avoid X-rays because they don’t want to put her under. Her dog is very active and jumps a lot. She doesn’t have a very good vet, so until she can find another one, what does this sound like?
