how long of a trial?

like i said, a real solid hunting dog should hunt, period... im not saying anybodys dog is bad, and handling a new dog mite take some time to adjust, but he should hunt for whoever is hunting him. If i go to buy a 1000$ dog and turn him loose and he pees on a bush and comes back to the wheeler he is gone back, no more chances. if he wont even go to a bay and they want 800$ for him, he is gone back...if he jumps the first deer he sees, he is gone back.. he should hunt out of instinct and not much should change his instinct to hunt. I do no that it takes time to adjust to different styles of hunting and different terrain, but learning his name for a week should not affect his hunting ability. One more reason to hunt with him and his owner before you ever take him with you... see how he is hunted, and where, see what you can expect from the dog once he gets use to you...it is better than a 6 month trial to me to see the one he is use to handle and hunt him, saves the potential wrecks of having someone elses dog on trial.
