This is what OUR CLIENTS have to say:

“The items were just as described and work perfect! When people say they can still hear it you really can’t its faint you hear a little bit but not what your dog is hearing so this works perfect. I set my whistle to a pitch my dog responds too and keep it on that so when I use it he knows its me calling him. Works great!!” – S. C.

“This has been a great training tool for my pups. The whistles work great an can get to a loud pitch noise. However it’s not necessary as it seems to work great to get my dogs attention even at a low volume. It’s been a fun learning experience on training my pups with these new tools! If your tired of yelling across your lawn to get your dogs attention, I recommend purchasing this!!” – K.P.

“This is the perfect set for me to start training my dogs. What a great value!! With some research, I’ll save SO much money on dog training. And I won’t fear to take my dogs on a walk any longer.” – W.K.

“Works great at getting my overly excited dogs attention when we’re out for potty breaks. Comes with two whistles and a clicker. They both come with the wearing device (lanyard or keychain) and are so light weight. Good quality for the price.” – A.K.

    I like it much! The whistler it’s portable and I can take it to the garden, so i don’t need to be at home for his training.
    I whistle at him a bit hard when he barks, he now understands that I want him quiet, it costs a little bit so your dog gets used to it but it works!! My house has been more quiet.

    This is the first dog whistle I have ever owned. It is easy to use. You simply adjust the frequency by adjusting (turning) the nut and screw . Once you’ve found an ultrasonic frequency that your dog can hear, training can begin.

    I bought this because I have a Yorkie. I love him very much, but I just don’t want me to go to bed in the morning. She can actually bark for hours. This whistle is great, I can control her barking now

    Well, I got this dog-whistle for my Poodle. This little guy liked to bark at a stranger when we go outside together.

    This is the first time I’ve used it to stop his barking. To my surprise, this small stuff is awesome that when I used it after a few training sessions, he stopped barking!!! I never knew that this cheap whistle can be so effective.

    Also, this dog whistle is small enough and easy to carry. I prefer to wear it around my neck thanks to the lanyard it comes with. Therefore I don’t worry about losing.

    I loved it so much!!

  8. Amazon Customer

    The whistle is small, so it’s easy enough to keep in a jacket pocket; however, I really appreciate the lanyard that comes with it, as I can wear it around my neck without fear of losing it. The whistle quality appears to be top notch, so I don’t anticipate having any problems with it, but if I do, I appreciate the money back guarantee that Hivernou offers. If you’re looking for an affordable dog whistle, I recommend giving this one a try.

    I can’t find the original whistle, so I bought a new one. The appearance of the whistle is well received for its workmanship and used well.

    The frequency of the whistle doesn’t affect me or others so it’s a plus
    I have not tried training with the whistle another actions since I only wanted less bark but I will.
