Even the most nutritionally complete dog food will fail if the dog refuses to eat it.

Even the most nutritionally complete dog food will fail if the dog refuses to eat it. Unlike humans, dogs rely heavily on smell (olfaction) and texture, with taste playing a secondary but significant role. This article explores how formulators can strategically combine ingredients to maximize intake, maintain consistency, and avoid palate fatigue. 1. The Sensory Biology of the Dog Understanding canine sensory priorities is the first step.
