Description Fishing takes patience, and that's just something that Thunder doesn't possess. No problem. With Blue Buffalo Wilderness Salmon Recipe, he can have a belly full of fish without ever wetting a line. Blue Buffalo's LifeSource Bits are cold-formed to retain all of the flavor and nutrients provided by the salmon, peas, and potato recipe. The grain-free, high-protein Wilderness Salmon formula is inspired by the diet Thunder would eat in the wild.
