Help Needed. Our German Shepherd Dog has just turned 12. Over the past couple of months he has become very clingy. Took him to the vet and he had a temperature so the vet prescribed a course of antibiotics. A few weeks later the same happened again, the vet gave him a thorough examination and said he has some stiffness in his back legs and has put him on Metacam. This seems to be helping him with his pain. But on several occasions the dose does not seem to be working. He's on the correct amount for his weight, 45k. Has anybody else experienced this and found a better way to help with their pets pain? I don't know what else to do for him and want to the best for our beloved pet. All advice shall be gratefully received.
