Is it food? Then Calypso is interested.
The argument against switching food types has to do with multiple protein sources and allergies. Dogs can only develop allergies to things they've been exposed to. So, the argument goes, if your dog develops an allergy to chicken (the most common), then you ideally have lots of other options--a fish food, a venison food, etc. The fewer proteins, the more options you have.
With that said, some things are pretty common add-ins/fillers/treat foods and aren't generally seen as alternate protein sources: chicken, fish, beef, pork, sometimes lamb. Really people tend to think of all-fish, deer, and rabbit as the allergy alternatives. (or the crazy hydrolyzed protein food if the dog is allergic to all meat, and...yuck.)
