Best way to stop baying at caught hog.

I would not use e-collar for that purpose at this age at all.

I teach my dogs that once I claim the hog it is mine, and to leave it alone. This is easiest accomplished if the other dogs will bay another hog immediatly but that is not always the option. As a pack leader, if the hog is yours, they would not question your authority with out challenging your authority. I would physicaly block his persistance and make him get ahead. If he does not then the pack leader would challenge, then dominate and correct any insubordance of any of the pack members. it make take time, but he can understand this with out feeling punished for baying a hog, but rather accept as a canine mentality. I would try this as soon as you tie the hog and make all them leave it, before even putting it in the trailer where it will be moving and appear to the dog as more of a challenge/distracting. We also give ours the command as "Caught Hog" "Get Ahead" while doing so.

This also carrys over to the hogs in the pen, and most all my grown dogs will not bother a hog in the pen, here in my yard. It is way easier to teach this on a dead hog then one still kicking & grunting, and then move on to the live hogs tied up.
