Catch dog problem

My experience wth the AB's is been kinda what is mentioned above, but I rather work in the pen. Don't give him and oppertunity to catch wrong, and this means you will have to wheelbarrow the hog to him and only allow the proper placement and when he starts keying on where you want him to hit, let him grab and then let the hog go in a controlled situation where he can manhandle the hog, Do not use a small hog this gives them an oppertunity to release/regrip/rebite and still control the hog which is bad experience for them to learn. A bigger hog without teeth like a green 150lb green sow will teach him a lesson if he trys to change up, and will make him work, but he will learn he can control a hog by the ear and not from anywhere behind the shoulder. Don't use bay dogs at this time, don't have any thing else around that will boost confidence or help him do it wrong.

I have had this with AB's and my AB/Dogos, and Dogos, the pits are a different ball park.
