Been thinking a bit on your problem. I think I might have come up
with a viable solution.
Moan a bit to a couple of neighbors about the dogs. Then video the
dogs at the garbage cans, documenting. Then use something like this,
with paintballs, still taping.
http://www.sportsmansguide.com/cb/cb.asp?a 4164 Not expensive,
definitely not lethal, limited range, not loud. Then, when the
neighbors complain about someone paintballing their pooches, possibly
calling the law on it, you can then, very innocently, hand over the tape
to the nice officers; and, depending on your mood, deny any knowledge
that those were our neighbors' dogs. If the dog(s) keep coming around,
a flast of those plastic BBs in the rear should move them on their way -
I'd keep a shotgun very handy thos, just in case one decided you were
being too unfriendly. Fun for shooting cans in the backyard too, or
even in the house.
If it ain't broke, don't lend it.
