The Hammonds line is as smart as most you'll find. The basis that everything they've been based on is an actual purpose dictates and emphasis on intelligence.

Everyone here keeps mentioning the Bolio stuff and I only had one Bolio type dog, by way of pure Tonka Red Baron blood and I can honestly say, my Amos dog was one of the most intelligent and "in tune" dogs I've ever owned. Loved that dog.

Outside of that, I'll stick with what I know and thats the Hammonds Rufus/Alligator stuff.
