I think this thread is Waaaay overblown and people needed to get a grip about 100 posts back. A pack of over a hundred dogs ... please.

On the simple, and really practical side, if you have a problem with dogs or other animals coming around a pumped up supersoaker loaded with a light solution of sudsy ammonia in water makes a lasting impression.

They hate the ammonia smell and can't lick themselves to get it off because of the soap. The soap also allows the ammonia to sink into the fur so it doesn't just run off. They can't stand to be around the smell but can't get away from it or do much about it. For a day or so you have a very miserable critter.
