I have been bummed out for the last couple of weeks. I have hiked a lot of miles with my dog and we have loved every minute. He had been limping on one of his back legs. I took him to the vet and she said it is a possible torn ACL, she did Xrays and got good news that it was just a knee injury and should heal. So, now, he is on severe rest so that he can be better by the time it cools off so we can get started hiking again. Anyone out there have a dog with a similar story?
