I actually went to the gun store today to ask about them, they didnt have any but there was a girl there who had one. She said that it was pretty loud and would probably do the trick by itself, but she also said that it really didnt shock as bad, i am assuming like the ones that shoot out the prods, i guess its more like a shock collar. Which is fine. And i was totally thinking about my girls with the noise as well, def wouldnt have regular collars, we usually walk with slips anyways because its quieter (hate to stir up the neighbors dogs just walking by)
what i find interesting tho, is the few people i have talked too, said that when they go for walks they usually will take a big stick, or hiking stick, or seen people with bats! i always wondered if it was really that serious.
