My Burwick always had a problem with a limp a couple times a year so I always kept Metacam on hand. Now at almost 13 years old I see him slowing down and unable to jump up on the couch and not wanting to climb stairs. Also on hard floors his feet slip from under him a bit. So I experimented with a bit of Metacam for a few days. He seems stronger and more confident in his moves. However I am looking at the cost and wondering how often I should give it.
