I switched my two Chocolate Labradors to Natural Balance about three years ago after searching for a quality premium brand with no corn as an ingredient. My dogs had suffered from skin infections that I think stemed from food allergies and my vet said that Labs are sensitive to corn. I spent several hundred dollars treating my dogs for skin infections. Since switching to Natural Balance, we haven't had any skin infections or outbreaks - None!
The cost of the food is well worth it compared to the misery of my dogs being scaby and itchy. Their coats look great and they are full of pep!
