Here is what I posted in your post in the Predator Hunting forum:
The Parson Russel Terrier (aka Parson Jack Russel) is the show variety of the jack russel. I'm sure they still have the terrier hunting instinct that is so strong in a normal jack russel. Should do well, Kelly Jackson used a pair for a quite a while. One issue with a small terrier, is their ability to see over the grass or sage.
Just keep a close eye on him, so he doesn't get rolled up by a pair of coyotes.
