I grew up with Chessies, and they fit well around there as most of our bird hunting was for ducks and geese in the Columbia River, in the area we called the Mud Flats (river is braided there). I didn't have a dog of my own all the time I was in the military; living in the shacks and no-notice deployments don't allow for responsible dog ownership. When the direction of the military changed, I knew it wasn't going to work for me and I started reading on my last deployment to Bosnia. This was before the Web, circa 1993. I read Joan Baily's book on the Wirehaired Pointing Griffon and decided to give that breed a good look.
I ultimately ended up with a griff pup, Jäger, my first and best Griff, my heart dog. My wife also got a pup out of that litter; the breeder was a shirt tail relative of hers; one thing led to another and we've been together 25 years and 6 Griffs now. We hunt with friends who have Pudelpointers, GSPs and a few others. They are fine dogs and I enjoy hunting with them, but as good as they are, in the character department and biddibility, I truly do believe that the Griff is better than all of them for a dog with you 24/7. I would not recommend a Griff above others to somebody who will kennel their dog a lot of time, or who wants a big running dog.
I have often heard people talk about Griff's being underfoot, but that hasn't been our experience. Of course, that can be a trait a kennel breeds for and a trainer can certainly train a dog to hunt close or train them to hunt out further. We develop our dogs to hunt out about 50 yards or so, and allow them to develop a kind of workmanlike cast. They don't really hunt fast, they hunt deliberate and thoroughly - our dogs rather than the first two have all been from different kennels here in Montana. One thing about a more deliberate, paced hunting style/speed is that our Griffs can hunt all day, while our friends often head back to the truck to drop off one big running dog and pick up another for it's turn; our dogs can go all day at the pace we hunt them.
There are multiple breeders in this area; most of them are pretty good. For us, it's not so much the kennel name, but personal knowledge we have of the breeder as well as knowledge of the particular litter we're interested in. I think that the term "four wheel drive of versatile gun dogs fits them permanently.
