I have had a dog/dogs for the last 29 years. I have had a few different breeds including "Lab, English Springer, Golden, English Bulldog, and Boston Terrier. With that being said over the years and breeds, i have found that food can be the cause of many problems with your dog. "Some were strange to me like ear infections"????????
Post some of your problems that you have had with your dog, due to the type, or certain ingredients in their food.
