Layla has a cartophen injection which usually lasts about 6 months. She is on cosequin which I've now cut back to one a day. My vet tells me to stop the cosequin if she has rimadyl. Touchwood she is still doing well with her magnetic collar, we went for a really long walk on saturday and she bounced into the car. I have everthing crossed that this continues but I have been told that spondylosis can plateau for a long while. I still notice her gait is not right at the back but so far no more pain from her HD. (says she touching her head, touchwood) Hope Ice gets some relief and help from either the pool or the homeopathic vet. Thank you for your comment about Layla - she is an extremely tolerant and loving babe.
