The initial cost of a dog is the cheapest part of the deal.  You'll have to consider food, the equipment you'll need/want such as kennels, bowls, toys, training bumpers, checkcords, collar, leash, whistle, and e-collar will add up.  The gas to go train or hunt is another major expense unless you're lucky enough to live in a place with enough room for them to run.  Vet bills are another big expense, annual visits, plus the occasional trip to get sewn up after a run-in with barb wire or whatever they get into. Plus, whatever they chew up.  My 2 cents is to get a dog from a good healthy line, a line that has all been proven hunting dogs and you will have a better shot at success.   Good luck with whatever breed you decide.  Wes
