Pimg was just diagnosed with perianal fistulas and I've read that it's important to switch the dog to a single source protein different from what they are currently eating.
- Does 'single source protein' simply mean only fish, or only chicken, or only one protein source (rather than a blend like TOTW's 'duck & chicken' Wild Wetlands)?
- What about the fact that protein is often added to pet foods from vegetable sources like peas? Does this affect the single source protein?
- Or does 'single source protein' really refer to feeding raw in some way, shape, or form?
