I have been following this thread, and it is very interesting. I appreciate the detail you give. Like you, I too have dogs that are not true LGD breeds but which function the same way (and my dogs come inside a lot too - I leave a couple out to sound the alarm and then send out the muscle). I like the fact they are loyal to me and the place and so whatever animal belongs on the place is accepted.
I use a Shepherd mix, a couple of hound mixes (and recently two Treeing Feists (aka Mountain Cur dogs -- still puppies) that were dumped on my road. The Shepherd mix keeps things run off and will attack coyotes, coons, opossums, etc.-- she is the muscle. The predators don't even test her anymore; the winter pack of cvoyotes will probe my perimeter. My main issue right now is that my Buckeyes range really far out in the deep woods and so it is impossible for my Shepherd mix to cover all the ground. The hounds like to go running in the woods all day but are home at night (they are only good for barking at things).
Wanted to let you know I enjoy the thread. Btw, I stocked my livestock (I have cows and a donkey) pond with Bluegill. When the drought last year reduced the pond to about 6 inches, a Blue Heron pretty much cleaned me out but surprisely, some Bluegill somehow survived. The minnows are still numerous. I noticed your BYC handle. Before my life & profession now, I was a Paleontologist (geologist) with biology minor but know my largemouth bass, rock bass, crappie, bluegill (whatever else is a Centrarchid - they have been around since the mid-Miocene, thereabouts -- used to have a fossil one).
