My 7yr 62lb golden Max went to the vet 10days ago with symtoms of not eating, shaking, hind legs seem painful. He has trouble getting up and going down stairs and bending down to go to the bathroom. They took Xrays and he did show a very small amt of arthirtis in lower back and in hips but nothing major. They also did a blood test and all of his organs showed in good health. He has been on antibiotics and rymidal since and it seems like nothing has changed. He will seem like he feels better for a few hours and then we are right back to where we were. I have another appt for him this week but is there anything you can think of that I can bring up to his vet to check...
