Yep, I hate the invisible fences cause they work just as well as no fence. All of my dogs would be gone before the shock even registered.

I had the same response a couple of weeks ago while I was out with Boxie (4 mo great dane puppy). Some guy's dog came after him and when I used my foot to push the dog away by hooking him under the neck and shoving the owner was all "Don't kick my dog, he was just trying to mount yours"..well, screw you Mr Owner, by your dog's body language and actions he wanted to do more than mount the pup (which I wasn't going to allow anyhow)and IF I had kicked him you would have known it. Took all I had to not get in his face and just walk away because it wasn't worth arguing with him.

I second the cattle prod idea. Safe for you and your dog and a definite deterrent to other dogs (just be careful about using it on a small dog - might be too much for them!)
