Is Hills Science Diet a good brand of dog food?


Despite misinformation that Hills Science Diet contains fillers, animal protein is almost always the first ingredient in their foods, and when it is not, it is usually because the diet has been formulated for dogs with a particular health requirement, and not because of cost-cutting.

Hills Science Diet has a huge amount of research and testing behind their products, adding to the reliability, quality assurance, and efficacy of their foods.
