The Blue Buffalo Basics Limited Ingredient Diet Natural Senior Dry Dog Food Turkey & Potato was loved by reviewers at The Spruce Pets, a trustworthy source that performs objective hands-on testing. It did great in their "The 7 Best Dog Foods for Allergies of 2023" roundup - in fact, they named it their "Best for Senior Dogs". That, by itself, points toward it being a noteworthy Dog Food.

Taking a look at the Iams ProActive Health Adult Large Breed Dry Dog Food, we found that it hasn't managed to perform well enough to earn a spot in any Dog Food roundups done by sources that conduct their own, high-quality, hands-on testing. That alone makes it difficult to recommend.
