Dear Mike,

Thanks a bunch for writing. My goodness, I dont know how much good I can be on your question, but I'll try. Ive seen Rat Terriers in bay pen competitions. They were truely "live wires" and of course Ive seen pits in action on hogs. In regards to vest, its my understanding that boar busters makes a xx small vest for those type dogs.

In regards to keeping up, well I just dont know, guess its according to the land your hunting on. Some of the places we hunt the dogs have to hop over the grass or weeds, i dont see how a real small dog could do it. But yet, maybe they can.

Hope this helps,

Jim
