Our problem was when our neighbours are in the dogs barking sporadically is not a problem, but when they go out, all hell breaks out, the dogs go berserk constantly barking and howling driving us to distraction. So we must solve this problem. So we got this anti barking device. It works immediately.

The product was as described and it arrived in good time. The product is easy to clean. I use it outside. Good for training and keeping the yard clean.

Maybe in his young age, my dog is becomming naughty these days. He grow in bad behavior, bark at everyone and everything. Totally out if control. So I think I should found something that no hurt him but work effectively. And this is the thing. Just few day and he knows how to behave himself.

Arrived in a timely manner and good price. It would be nice if this product had some sort of clip on tab for the mat as the dog makes the mat slip off the tray. Other wise the product is fine

Neighbor has four completely undisciplined dogs who bark angrily at my wife and I, our two kids and our guests through the fence. This device allows my family to use our back yard again. They bark for a minute when we first come out, and then it annoys them so much that they leave us alone. I only turn the thing on when we are in the backyard because a single battery would only last a week or so but it totally gets the job done. We actually have two of them. Seems you CAN buy peace of mind, and I would have paid a lot more for it. THANK YOU!

We have had a significant reduction in barking from the neighbours dogs since I bought the bark controller. I am sorry I did not buy it sooner. There are a few barks and then they stop so I can live with that. It is great to be able to open the windows without having to listen to yapping dogs.

Very neat design and easy to use. I have 6 dogs, so they react differently to the ultrasound. Some stop barking immediately but the others can carry on for a while. It's like an ultrasound dog whistle - some dogs get it immediately while others take longer. It's just a matter of patience and persistence. In all, perfect.

Excellent product crazy puppies love crazy sales agility set. Crazy cheap price but perfect product from crazy sales
