Catch dog problem

You know, that may be Tyson's problem. He started out perfectly despite the fact that his first time to see a hog was one he bailed off an embankment into a creek to catch. He's never been in a pen, but hogs one through 5 were right on the ears. However, after those first hogs, we started sending him with other catch dogs. When he's caught, he's caught hard. However, nowadays he's catching whatever part of the hog he can get to. Most of the time that's somewhere on the head, but there have been plenty of times he was caught on a front leg and most recently he got ahold of a boar by a back leg. Eww.

I guess maybe he needs to HAVE to hold one with no outside help. We will try that. We love this dog, and don't want him to have a short life because the next catch dog may not be as easy going. This is a dog who will ride with any one of our other dogs - even my cranky dog who whips his butt for getting too close to HER part of the box (he can't help bumping into her when we have to hit the brakes hard).

Cheers
