Lots and lots of turnout? Does he crib out in the pasture?

The miracle collars are good, from what I've seen.

My Sheltie dog would chase the cribber at our boarding stable off the fenceline if I said "Sammy, go get .... um... whatever his name was... off the fence!" He didn't chase him around in the pasture, just off the fence.

In times of crisis, it is of utmost importance not to lose one's head.
