What matters to me is that good food can prevent and/or solve many problems including all sorts of allergies, bad breath, ear infections, loose stools, bad gas and many, many more.
Chester is 2 years old and has never had any sort of skin, ear or other problem and I like to think it's because my breeder did a great job and because I feed him good food.
In my personal experience, switching to a good food helps alot. Two of my neighbors have switched from Beneful to premium foods (Chicken Soup and Wellness) and they have told me that their dogs no longer have skin issues and their poops are much smaller, firm and consistent. One of the dogs is a 7 year old Chow mix and the other is a 3 year old Lab mix from the shelter. I can't believe both of them were feeding Beneful but that just shows you how powerful TV ads and other marketing can be. I HATE those stupid Beneful ads...they are so deceitful.
Anyway...that's my two cents. Thanks for your time!
