This is series, the problem is hugh. It's a recent phenomenon. I haven't lost anything only because the dogs are loose at night. Colleagues have had container, ball & burlap stock stolen, and several cases in California, where the varmits dug speciemen plants from the field. In one incident a Japanese Maple worth mega bucks was stolen from a display garden in the front nursery display.
"I suspect a Longhorn versus a wolfpack might be a little one-sided."
Me too. The cows are herd animals also. I really don't know if the other cows would stick around and duke it out, or act like their barnyard friend the jackass and run like girls when the going gets tough.
