I haven’t heard that. Your dog is lucky to have different food types per day. Can you imagine eating the same food for years and years? I feed raw dehydrated for breakfast, a 5 star kibble for lunch and another 5 star brand for dinner. As a side (not mixed in), I rotate a canned food daily. The stools are medium sized firm and I make sure the total daily amount matches their activity level for the day (lots of swimming as summer approaches!). Dasuquin Advanced as treats and deer shank bones in between. Vet visits are a thing of the past. Just watch for any allergic reactions when introducing a new food.
