Overview

This formula centers on real salmon and tuna as the named proteins, with natural sources of glucosamine supporting hip and joint health alongside broader claims around digestive, heart, immune, and skin and coat health. It's marketed with no artificial colors or flavors and a high protein nutrient content claim.

At $63.49 for a 36 lb bag, the cost per pound is reasonable for a fish based, all breed formula of this size, though it's a lot of food for a single small dog to work through before it's past its best quality.

With 5,920 ratings averaging 4.7 stars and about 2,000 units bought in the past month, this reflects solid and consistent satisfaction, even though the monthly purchase volume trails some of the highest selling formulas in this lineup.

Real salmon and tuna with natural sources of glucosamine for joint support
