I start all my pups like that. Once they get to where they can find a hog I know is their then they ready to hunt
x2, However, I hunt them as long as they want to bay a hog.
If the pups are catching the staged shoat, then you need to put a bigger hog in front of them so that they can learn a little hog respect. Otherwise they could get hurt badly or killed on the first big boar in the woods they encounter on account they won't know any better. I made this mistake years ago and I almost lost the best hog dog pup I have ever owned. Luckily he lived over it and went on to be a real hog dog.
