Trixie High Frequency Dog Whistle - With Frequency Protection

I have always used dog whistles as I have three dogs - and need to keep them in order. This whistle is not very loud and unless the dog is within 6 ft of the person using it, then they do not hear it. I have tried adjusting it but cannot make it louder. Resorted back to my plastic dog whistle which works.

I bought this as we used dog whistles in our training class. The ones I used in class could be heard where as this one is an almost silent whispery noise. I'm not sure if only dogs can here it? I tested it out by getting my dog to stay behind a wall and then blew it three times and he came but I wonder how well this works outside on a windy field? I'd be interested in hearing if anyone has had success with it? I gave it a middle star rating as I'm not sure how confident I am that it works, I prefure the ones I can hear too!

I just left a review asking people if this worked outside in a windy field - shame there isn't a q&a section on this site! Anyway I wanted to come back and alter my original 2 stars as I didn't have confidence because I couldn't hear it but low and behold I called my dog in from outside using it so I can confirm it does work! It's just a bit weird at first as the ones I used in training I could hear too so that gave me more confidence in the product! Please accept this resubmission of my review as I feel I was unfair the first time round!

This whistle is a waste of time and money, tried it once and then binned them. Avoid this item and buy a decent one.

I purchase the whistle for gundog training. Big mistake! Firstly the mouthpiece is so short you cannot hold the whistle in your mouth. Secondly it does not sound high frequency at all. Buy once, buy right and forget this one.

AFTER I've adjusted the whistle, it works perfectly well. My dog hears the sound and knows what has to be done! Of course we needed time to get used to the whistle instead of loud commands, but now it works, I don't have to shout any more! The whistle is great for beginners!

This whistle is not silent, it kind of 'whispers', plus my dog just looked at me then boxed his own ears. Obviously not a noise that will have him dashing to my side. Good cheap price but you get what you pay for.
