Any advise ??? My 2 1/2 year old boy Duke has injured his back leg some how. He has been limping and sometimes walking on 3 legs. We took him to the vet they checked it and said he pulled a muscle, gave him some anti inflam meds and told us to try and keep him down for about a week (yeah right!!) it didnt get better so we took him back for x-rays, but nothing showed up, nothing broken etc.., they checked his hips too which they said looked great. It has been 1 1/2 months now with no change he is very sad, not being his happy self, has anyone had this happen? does anyone know how long this could last? Tisha
