To Kullboys,

With rotating dog foods, the idea is that by allowing short exposure to a wider variety of protein types, the immune system is primed to a larger range of potential allergens, which strengthens the immune system and may reduce the risk of allergies or symptoms developing, this is particulary “Important for YOUNG animals”.
Added benefits, a rotational diet allows a better chance of providing a more complete and balanced diet. While most dog foods sold commercially have been balanced to meet nutritional guidelines there is always a chance that one brand might be a little deficient in a nutrient compared to another brand, by rotating a variety of foods your pet is less likely to suffer any deficiencies as they will draw whats needed from other diets..

Dog Food Advisor recommends to rotate your dogs diet, DFA is where I learnt to rotate & strengthen Patches Intestinal tract.

Here’s a parragragh from DFA post

“Isn’t changing dog foods dangerous for the animal?”
Although some pets can’t tolerate menu changes, I’ve never been able to find “a single scientific study” proving diet rotation to be unhealthy or detrimental to a dog.
