Help with teaching 'caught hog'

We would just claim the hog as a lead dog would do on a kill. Hover over the hog and tell the dogs in a stern voice "caught hog". I will even so much as stretch my arms out as to let them know to get back or else. Swatting at them if they get too close. Have someone pull them off if they are still too excited to listen. Most of our dogs will obey this command but we have a few that just refuse. I never attempt to teach this to the catch dog. I like to have to force him off the hog and clip him up so if something goes wrong, all we have to do is unclip him.

On rolling out. When ever we put the dogs on the ground at the beginning of a hunt, I have words and cues to get them going like "get ahead, and little sic'm noises. So after I claim the caught hog, I will do the same thing to try to get them in hunt mode again. This takes patients and lots of doing it over and over until they hopefully get it. This is more sucessful if the dogs hit a sounder of hogs and then got one stopped.
