2 in 1 Dog Training Collar Automatic Anti Bark Control with Remote Rechargeable and Waterproof for 2 dogs

This collar has fixed a lot of problems in our household. Our Jack Russell mix, Jack, (he came with that name, so don't judge us on our lack of creativity) has a very annoying, high pitched bark that he loves to let loose at the slightest sound or movement outside. Hours of sleep, tv time, quiet moments reading a book, etc have been lost due to the shrill decibels emanating from his voice box. It could be the garbage truck, a neighbor having a BBQ with his family a block away, a leaf falling on the sidewalk, and so on. He's also a bit of a jerk to the other dogs, growling, barking and nipping at them if they come too close if he is sitting on our laps or beside us on the sofa. We tried various training techniques such as saying "No!", spraying him with a water bottle (he found it refreshing) and positive reinforcement with treats (as soon as the treat was in his gullet, the barking ensued). I finally decided enough was enough (actually we received threats from our landlord) and purchased this collar. I haven't had to even use the electric static charge on it, just the vibration mode.You know how people say that you can't purchase something expecting it to change your life? Well, they're liars! I put this collar on and all of our dog problems have miraculously disappeared. No more barking, no more growling and being rude. Jack will now stare out the window at another dog walking by and just emit a little "Hmmm" whereas before he would have lost his sh*% and gone into his best Cujo impression. He no longer nips or growls at our other dogs, but now even allows them to lick slobber all over his face, again with the little "Hmmm" and a somewhat pained expression on his face, but still. He is no longer Jack the Jerk, but Jack the Gentleman.I take the collar off every few nights or so for an hour to recharge. During that time Jack has tried a couple of time to resume his old bad habits, but all I have to say is the word "collar" and he immediately shuts up. Thank you A+ Trainer. Your product has brought peace and sanity back to our household.
