Title: Works good on some dogs
Review: I have an aussie/husky mix that barks alot so I bought this on a recommendation and when i was training him and he didn't listen i'd zap him, he noticed it but he just ran away confused. After a while it didn't even affect him. However, I have relatives that have a really small dog, and it works great on her. So it just depends on the dog i think.
