6 months - must show intrest even if it is only for 5 minutes or so, if not they get 6-10 more tries before they are out
8 to 12 months - must be running with finnished dogs and helping bay/catch
15 months - must be finding and baying/catching their own or they are out the door
We recently sent a 10 month old gorgeous male down the road due to no interest, the man that had him before said he was baying/catching everything in sight....our 6 month old put it on a good boar hog while he walked around the yard smelling the daisies.
We have gotten rid of some good dogs but right behind them were some even better ones.
