ACME Alpha 210.5 Professional Dog Training Whistle with Enhanced Ergonomic Grip. BPA-Free Plastic. 110 dBA. Standardized Frequency for Smaller Dogs. Weatherproof. Made in The UK (Forest Green)

My dog is losing her hearing, but she can hear this whistle. Saves my having to yell at her when I want her to come to me.

Works as represented.

I have a dog that when you get its attention is quite obedient but sometimes gets zoned in on rabbits under the wildlife. This high pitch whistle grabs her attention and she then listens to my commands.

Did not keep my yorkie from barking, unfortunately.

I"ve been using the less expensive Acme 210.5 and decided to try the Alpha.. It is much easier to blow and can be a bit louder so I can work my Spaniels at greater distance. It really gets their attention when they are locked in chasing swimming ducks, (their worst of many bad habits), and on dry land their recall seems more energetic and focused, which potentially can be a true life saver. Because this whistle has a sharper clearer sound, they seem to pay better attention in all commands and we are both happier when they respond successfully. I recommend this for anyone who is looking to successfully train Spaniels.

Good price.

Not really a dog whistle if you want a silent whistle only a dog can hear. It has a high but not piercing sound so it's not hard on human ears. My dog responds to it well. He is a rescue and I think he was exposed to a whistle before I got him so he is easy to work with. I like it and easy to keep on my key chain, colorful.

My puppy just ignored it. Really didn’t do nothing. Thank you
