Well you are right about Mcdonalds but Leika hasn't shown yet any signs of allergies or anything that would have to do with Eukanuba. But you can't keep your dog feeding all these healthy and diet foods. 'cause everyone needs fat. It might be true that they have all these sort of things that look gross and is bad for us but maybe is not for our dogs. Anyways if I wanted to change the brand, I just couldn't 'cause at the moment in my country Eukanuba is the only dog food that provides extra vitamins and stuff for smaller breeds which makes the pellets smaller so Leika doesn't have any problems eating them.
