Hey TropicalStorm, I notice that you’re in Alberta. Which area? North, South, Central, East or West? I live in central Alberta, (Moved here from southern Ontario, a year and a half ago) It was quite the culture shock. I’ve moved to a rather, how shall I put it, red-neck area. If I went to the police with a trespassing complaint, I’d probably be laughed out of the place. I know, not the right thing, but not something high on the cops priority list.
The way they deal with trespassing dogs around here is with a shotgun. No, it’s not very nice, but frankly, if it came down to my horse running all their weight off, scared all the time, crashing through a fence to get away from a dog “who likes to chase horses”, that dog would disappear, even if it was just to take it to the humane society.
By the way, for anyone who wants to flame me for saying to get rid of the dog, unless you’ve seen a horse be put down because it destroyed it’s leg crashing through a fence to get away from a dog, you have no idea how awful it is, and what you would do to stop it from ever happening again.
