To start off with don't get me wrong I am no pro what so ever.
I have really just got into really training pups. I am not so sure
what age you would want to start yours at, but at a little over
8 weeks I get a shoat in a very small pen and let the pups run the
outside just to let them get the sent of it and get interested in it.
I do that for a little while every day. When they start trying to mess
with the shoat thru the wire I put them in the pen with them to see
what they will do. Also we take ours on hunts with experienced dogs
and like they said before when we catch a hog and have him tied
we take off our catch dogs and such and let the pups play with it
minute.
This is just my way, some people may think I am completely wrong.
But hey its just my opinion. right
like i said no pro here.
An ole farmer that hunts still taught me this
