What is a likely result of feeding a GWP a diet lacking sufficient high-quality protein and fat?

Answer

The dog may become sluggish or struggle to maintain body condition.

Since these dogs are built for high output activities like retrieving through thick cover, a diet deficient in quality protein and fat will hinder their ability to sustain energy and maintain appropriate physical condition.
