Interesting article..... Spaced on the fencing of the perimeter of my place I have about five or six signs WARNING LIVESTOCK GUARDIAN DOGS WORKING DO NOT DISTURB. One on the front gate. Unfortunately some people still come too close to the fence, but its getting better. I need to put up a few signs that say CAUTION STAY BACK FROM FENCE. On biting and breeds.....I would note from my own experiences with owning several breeds of LGDs there can be a vast difference between individuals within a breed so take the figures cited with a grain of salt. I own two Spanish Mastiff males. The largest one is intimidating enough merely from his size, and he seems to know it, and although he will sometimes charge the fence - or trot up to it more like - he is not aggressive towards people once introduced, or if they show no tendancy to provoke anything. My younger male mastine, on the other hand, has recently gone from being intimidating to downright aggressive at the fence. He will not let anyone touch him anymore other than myself. He will come up to the fence and if someone reaches in, he will snap at them. This has all just started in the last few months. When friends come in now, he will observe them, remain distant, but never quite take his eye off them. My female mastines, vary as well; some are vocal and intimidating at first then settle down and let people pet them. Others more aloof. My point being, within a breed, there will be vast differences. But again thanks for posting links, good information there.
