Boozer

Boozer is an informal English word meaning a heavy drinker, though as a pet name it is typically given with cheerful irony — suggesting a dog who laps up water or affection with equal enthusiasm.

Boozer is the name for a dog who approaches everything in life with gusto — food, water, walks, attention. They don't drink water so much as attack it, don't eat dinner so much as inhale it, and greet affection with the same uninhibited enthusiasm. Nothing half-hearted about a Boozer. Full commitment to every moment.
