I've been musing about changing Quinn's food to a single source protein of Salmon from her current Turkey, Duck & Trout recipe (within the same brand) to help with her dry and itchy skin. This has been suggested to me a few times now and obviously I had to go into research mode. However, I would likely not be able to stick to feeding fish only treats (I could try). Would this make the food swap pointless? Also, the salmon recipe is 22% protein and her current food is 34% (both grain free). I called the company who said that I shouldn't see a difference in her condition, as dogs draw energy first from carbs, then fat, then protein but that protein does helps build more muscle. Quinn's condition right now is great - sleek and well muscled. Is it crazy to mess with her food?
