My 10 year old Lab cross male dog has been lifting his front left paw when sitting and standing, and is bearing more weight on his right front paw when walking since the end of March. The vet has done a physical examination and he does not cry out in pain, and he was put on Metacam, but he continued to lift his paw and bear more weight on the right. X-rays have been done, all of which were normal. The vet then referred us to a specialist vet who did further X-rays with contrast and a joint tap (fluid taken from his joints). All of which have come back as normal. Images were taken of his elbow, shoulder and wrist. The specialist vet is now wanting to do a CT scan and possibly key hole surgery for investigation purposes, and says he thinks it may be elbow problems. At the moment I am reluctant to put him through more tests if no diagnosis can be provided. He doesn't cry out in pain, will let you touch the paw, will happily go on walks, climb stairs, get in and out of the car, will play and is generally his usual self. Has anyone else had a similar experience with their pet? At the moment I'm unsure to continue with the tests or keep going with the Metacam and see how he gets on.
