My dog hears this whistle also very good and at the beginning he was also very interested in running up. But it would be a fallacy to think that a dog is not trained to whistle comes, just because you whistles with this whistle. These already heard a bit of physical training, patience and perseverance.
We are now working for 3 weeks with the whistle and my dog understands what I expect from him when I whistle, but unfortunately he is still in puberty and has its own head.
But since I do not feel the sound of the whistle as unpleasant, it is not so bad that we are still in the training phase for me.
I would buy the whistle again and have already recommended it in the dog school.
