I like NDD's bomb blanket idea. I'd just hate it if chomper was keen and got loose only to get a mouth full of tactical ass!
Cattle prods are always fun. Especially on city folk. Had a friend that was always touching the fence, took the prod, placed it on the wire to see if the current was enough to give him a jolt. It was.

I grew up on a cattle farm in Missouri, I've seen and done worse.
