Interesting that livestock is the primary concern—I'd imagine interactions with other dogs (which can be highly stressful, though this varies a lot from dog to dog) would be the primary issue these days.
What is this world that some of you seem to live in where interactions with other dogs are, apparently, incredibly problematic?
Dogs encounter eachother all the time when you're out on a walk and it's... fine (again, I'm talking UK here). What's the worst thing that happens that you're all paranoid about your dog meeting, gasp, the horror... another dog?
Depends on the dogs. There have been a few dogs in my neighborhood that have attacked other dogs, with the dog that came off worse requiring veterinary attention. In one case the dogs were on leash, but each probably outweighed the walker.
To be fair, I am talking about three or four incidents over twenty years.
