I hunt with a couple folks that run Griffs. Both AKC dogs and WPGCA lines.
The AKC dogs are stout and hairy. Very methodical, close-working dogs that are hard-headed to a fault. Nice personality, friendly and funny.
The WGPCA dogs are much bigger running dogs, with the energy level to match.
Both lines like to chew, alot. Constructively or otherwise.
Tons of prey drive, very vocal and affectionate.
