Dog Bark Control 50 FT Range Stop Barking Device, Ultrasonic Anti-Bark Device, Safe for All Dogs, Indoor & Outdoor Use, Dog Training Tool and Sonic Bark Deterrents Device Let Stop Barking Dogs (black)

It works great! The neighbors big dog barked constantly, and very aggressively through the fence at my 3 yr old daughter as she played about in the yard. Since I placed this anti barking device near the fence the dog never barks anymore or even comes near the fence. Best investment ever.

3 dogs show absolutely no indication they hear anything, no matter which setting, which way it faces, or how close it is. The light blinks, it has power. Don’t waste your money.

works great for my dobermans doesn’t work for my lab

Didn’t work even on my small yippie pup. They hear it ya but it doesn’t bother them in the least, even turned all the way up to it’s highest setting. Don’t waste your money.

Does noting for my Golden. Useless. Waste of money.

Just don't work

Have 3 dogs that would bark at anyone, even us returning home. This device works fabulous.

el mismo no sirve para tranquilizar a nadie el perro ladra con mas fuerza hace el efecto contrario no comprar es una fiasco
