Hun Hill Magnum (Coop)
NA 110 Prize I
Hun Hill Magnum, (or as we call him, Coop) is our Wirehaired Pointing Griffon stud here at Mountain River Griffons. He comes from an incredible lineage— his grandsire, VC CH Griffe D’Automne Mr. Brown (2006–2020), is a name well-known in the breed, and his sire, HG’s Cota’s Keoki (CK), earned a NAVHDA NA Prize I (112) and UT Prize II (197), owned by George DeCosta, Jr.
Coop has certainly carried on those traits. He’s an outstanding hunting dog with strong natural instincts, a high prey drive, and the athleticism to cover ground with ease. In the field, he’s focused, fast, and dependable. Several of his puppies have already earned NAVHDA Natural Ability Prize I, and many of his sons has gone on to achieve a Utility Prize. Most notably, his son Gauge Vaughn Mountain River achieved the coveted NAVHDA Versatile Champion (VC) title at the 2025 NAVHDA Invitational at just 2 years and 3 months old, making him the youngest dog to earn the VC title at the 2025 event. This accomplishment is a true testament to both Gauge’s ability and the strength of Coop’s lineage.
But what we love most about Coop isn’t just his hunting drive—it’s his heart. At home, he’s the very best family dog. He’s affectionate, gentle, and absolutely wonderful with children. He has a playful, goofy personality that makes everyone around him smile, and he knows how to “switch off” at home after a day in the field.
Coop is the kind of dog who’s not only your trusted hunting partner but also your best friend and a loyal member of the family. His puppies inherit his intelligence, drive, and athleticism, as well as his fun-loving, easygoing nature that makes them amazing companions.
We feel blessed to share Coop through his puppies and can’t wait for other families to experience the same joy he has brought into our lives.
