I wonder if the cartilage would work for my knees!! Let me know .
I would recommend Answers Pet food. It is raw. easy to feed and really the fantastic. All the kibbles you are feeding are bound to not be great because they are PROCESSED and limited. This is very low in carbs. It is fermented and truly wonderful. As far as I am concerned all dogs should be on a diet like this. You can feed just the meat which is complete and that will keep the calories down ( depending on how much you give him) and it will be so good for him. Contact the company and ask they about the Fermented fish stock they sell this may help his joints a lot. I know the owner drinks it herself because she had a broken back at one point. Good luck and keep me informed!
