Go to NAVHDA for good resources. If they're doing any training or testing, give them a visit. You should look for breeders right now. We have a friend that's been on a breeder's list for a year.
There's a national market for pups, so don't be afraid to look far and wide. We're in Mt. and had buyers in Wisc, NC, Fla and Canada. Many breeders, like us, would only sell to people that were looking for a hunting dog.
In addition to his book, DeCostas also has a FB site. Another on site on FB is Training the Versatile Hunting Dog, and Hunting Wired Pointing Griffons.
From personal experince, they do require a soft touch. We use shock collars on our dogs. Our bitch (pictured) responds to the buzzer on her collar. Level one is too much for her. Kathy was just reading this over my shoulder, and said she had to use level one a few days ago
because she was chasing a cat. She said Bree screamed like mad. The stud we had was a bull head (the breeder named him Dozer), and he needed a level one, except when we first went into a field to hunt. I would purposely give him a few basic commands as we left the truck, knowing he wouldn't respond properly. After shocking him 2 or 3 times at level 3, he would look at me and say "Ohhh, are you talking to me?" After that, he was good for the day.
He and I would go duck hunting. I jump shoot ducks through the end of the season in January. The coldest weather we hunted was 15-20 degrees below zero. The thing I like the most is that they are close working and pointers. I've chased labs and goldens for miles, and I can't do it any more.
