I have a turkey dog that I trained myself, she is a dropper (pointer/setter mix), I named her Maizy. Any bird dog that will scatter birds and bark on the flush will work, but most guys use either boykins or droppers. Not a whole lot of training involved beside general obedience and teaching the dog to sit still while you are calling birds in. If you want to know anything about turkey dogs, check out the AWTHDA website or send me a PM, I'd be happy to tell you what I know or point you in the right direction.
