Q. Dog with arthritis, what can I give him?
A. Arthritis is a common condition in old dogs and cats. I always recommend to start with less and add if necessary. I would start with joint supplements (that contain glucosamine and chondroitin sulfate) because they are been proved to improve the inflammation and pain from the joins affected and they don't have any side effect on your dog. You need to use them at least 3 weeks to see an effect. If that's not enough I normally add NSAIDs, like meloxicam (Metacam) or firocoxib(Previcox) but those are medications that can affect renal function especially in old dogs. In that case I always check the dog's kidneys every 3 months with a quick blood test to know if they can continue on that medication or we need to swap to a different one.
