"I reviewed alot of products to stop my schnauzer from endless barking including the bark collar which of course didn't work. I have an electronic fence so it confused her, and when she found out it did't buzz her she just kept barking. I decided to get this trainer to try and on the very first day it started to work and it has been a blessing. Now all we have to do is say quiet and she stops. I absolutely love it. Next I will try it on her jumping up on people which my husband started and has become a bad habit. I would recommend this to anyone who is at thier witts end."
