DiViPets Ultrasonic Dog Training Whistle with Lanyard and Ebooks, Black

This was purchased as a gift for a friend. They told me when they used it the dogs stopped barking. For the money it's worth a try if you have barking dogs nearby.

Review by our daughter (the user): The whistle is good. I like that you can adjust the volume of the whistle and see what the dog can hear. I also like that it is on a lanyard so it is easy to carry. Also, my dog really enjoys it.

an alright whistle for the cost... not all 5 dogs respond to same adjusted sound. Wish had come with instructions

Very temporary effects, maybe one or two blows stood them from barking, then it has no effect. At least that was my experience with two adult pit bulls.

Lanyard tore 2nd day I had it

Does not work. The dog does not stop barking.

Did not work for my small rescue dog - part terrier part papillon - Bummer!

Doesn't work...don't loose your money!
