Is Hill's Science Diet a good brand of dog food?

Yes! Despite misinformation that Hills Science Diet contains "fillers" for cost-cutting, animal protein is almost always the first ingredient in their foods. 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.
