Surely 'the hunting game' is all about picking a pup you like, then putting all your time and effort into that pup, building a bond so that the dog will do anything, even give its life if necessary to work for you.
Granted some dogs just won't make the grade and that's a fact, but this fella has had more dogs in 6 months than I've had in my adult life, that cannot be coincidence! I don't see what joy is to be had from chopping and changing dogs after a matter of weeks because you don't like them?
