I am new to this but needed to find some information on some health problems with our beautiful boxer. He has gallstones and arthritis, but today he was also diagnosed with a possible pinched nerve in his neck. Has anyone ever dealt with this before that could tell me anything about it? He is taking Rimadyl (which he had been off and on for the arthritis) and glucosamine, but is now also on a synthetic opiate or "doggy morphine" as the vet called it. Are there any really, really good brands of glucosamine I should buy that might help better. This is our baby and we love him dearly! Any info. or response is helpful. Thanks so much!
