Sorry for the delay, I actually moved my older house dog outside to the pen with him. She had become incontinent in her sleep and it was a decision I was struggling with for a while now anyway. I'm not trying to be too hard on him. I am out there every single day tending to his needs as well as my birds needs. He hasn't just been ditched in the middle of a field with bowls of food and water for company. My problem is all the experts and books seem to say an lgd not staying with the stock is an lgd not protecting that stock. Some even implying that if a lgd prefers to be near the house/humans and refuses to stay with their stock to be not suited as a lgd at all but rather a (protective) farm/house dog. This is why I'm at all concerned about the behavior.
My farm isn't under heavy predation right now. But to give you a better Idea of when it is and what to; I had 20 Australorp chicks and 3 Banty Sultans I got last spring. 1 Australorp and 2 Sultans died of natural causes during brooding. 15 Australorps died to 2 dog attacks(13) and 1 fox attack(2) and the remaining Sultan died to an Owl or Hawk during summer (this one I did not witness). I got 20 more chicks in fall, this time EErs, 18 died or had to be put down after a hawk attack that left them horribly mangled (they were fully-feathered adolescents in rabbit cages and the hawk pulled them through the gaps trying to eat what it could - it looked like a raccoon got them but I had to run the hawk off myself so I know better). It is now nearing a year of this game; I purchased 43 chicks total, 3 died of natural causes, 34 died to predation, and only 6 lived to this point. Hawks and dogs are my biggest problems (and in foxes in previous years). I've seen and dealt with possums, snakes, and raccoons being in and around my coop but none of them managed to do any damage. (the raccoon did bite one of my birds but he only got a mouthful of feathers before the house dog ran him off proper, that hen is still alive today)
So yes, it's a good and determined variety but he's already at least twice the size now of 90% of my problems. No coys or feline preds (other than passing feral cats), the foxes have gone away months before I got him, and the dogs I've had issues with were all small enough to wiggle through livestock fencing; about 1/4th the size Kobu already is.
