I spent alot of time researching dogs to get the breed that I was looking for. I do alot of upland and waterfowl hunting, I was also looking for a good dog for the family, one that travels well because I do alot of driving and wanted him to tag along. Your best be is to spend the time figuring out the breed you want. Once you have done that finding a breeder is equilly as hard. You want to make sure it comes from a good blood line. The old saying you get what you pay for might play a roll in this, however, if you research enough you can get that expensive dog for alot less money if you put the time into calling around. For instance, I got my dog for 400, his father was 1500 and mother was 2000, which means I got a great deal, they are out there, but if you can't find something thats not expensive.... it might pay to pay.
Once you've found the right breeders, if able go spend some time with the parents, even better if they let you hunt with them. I am a firm beleiver that the type of dog you will get is at least 60% of what you will see from the parents so this is one of the best ways to find the right kind of dog. When I got my GWH he came from two of the best lines I could find, both parents had lots of awards but that wasn't all I was interested in. I had to spend some time with the dogs to really get an idea of what they puppies would be like when they grow.
When I picked the puppy I didn't pick one the first day I went. I accually spent a few days visiting and watching all of them, took some notes watched them play. You would be surprised at the differences each time I went. the first time I thought for sure I knew which one was the bully, which was the shyist, the most outgoing, and the most lovable. Everything changed the next day I was there. I decided that the more time spent observing and playing with them the better. I finally came to a conclusion between 2 of the 11 pups by the 5th day and beings I wasn't getting the first pick I had to wait but luckly got one of the two I had hoped for.
Just figure, Your planning on spending over 10 years with this dog, countless hours training, way more money that you plan on vet bills, food, toys, training stuff and everything else you don't think about.... so whats a few hours a few days while they are puppies going to matter.... in most cases alot I have found.
Now if you are looking at breads really do your research. Everyone is going to give you their fav. breed. If you are hunting both upland and waterfowl you should look for a dog that does both. Are you looking for a flusher or pointer? Do you want a close hunting dog or ranging dog, are you going to be hunting with large groups of people or just a few. All these things and more play into what breed you will want to go to. I can make some recomendations if you would like to let me know what all you are looking for in a dog just let me know.
