Hello all,

I have an about 5.5 year old male Doberman Pinscher. He was neutered around 6 months old, not too sure if it matters.

My boy really struggles with a sensitive stomach. I've narrowed it down so far that he's more than most likely allergic to chicken and all poultries and maybe beef as well.

I currently feed him Canidae Pure brand dog food, lamb, goat and venison recipe, which he does well on for the majority of the time. I believe he does the best with bison and venison but was wondering what other options I might have or a good recipe to follow from anyone with a similar dog.

I'm also aware of the heart issues and joint problems that can usually come with dobermans as they age so I really want to be proactive.

Thanks !
