Bought more than one years ago and use it frequently with RECALL. Whistle will not make your dog stop barking simply by blowing it! (It may initially if your dog is curious, but the effect wears off quickly.) Here is how to use it for recall (barking stops if she is coming to you, by the way.)As with any whistle, it must be “primed” first by associating treats with the whistle. E.g. Feed your dog its food by hand for two days, a small handful at a time. When your dog is calm and looking to be fed, blow the whistle (I use two short bursts), say name plus “sit,” and feed part of the dog’s breakfast out of your hand. When done, praise heavily. Step away, get more of the meal in your hand, and repeat the process multiple times [3-5 whistle bursts per meal] until the food is gone. Repeat at dinner or the next morning. Usually 2-4 meal time pairings of whistle plus hand feeding of meal is enough to make the connection between the whistle and food.Next step: “prime” recall. Have high value treats ready in the house and whistle on a lanyard etc. When you catch your dog turning towards you or [better yet] coming towards you on its own, say its name plus “come” and then blow the whistle sharply. Encourage your dog as it comes to you (“come on, good girl, let’s go” etc). When she reaches you feed some of the high value treat while praising. Repeat 3-4 time inside the house per day, pairing the whistle with her name, the command, and praise. Try to catch her when she is coming to you naturally as opposed to expecting recall when she is distracted. A few days of this inside (hallways work well as she has limited places to go, except forward towards you) and when you are ready, move outside.Repeat the high reward, name, command and whistle routine outside when she is close and moving in your direction on her own. Once this working, use the recall routine when progressively further and when more distracted (e.g sniffing or eating grass etc. A few days of recall outside 4-5 time per day should get the whistle established. Be consistent and reward generously with valued treats at first. Ease off in amount and type of treat as she becomes reliable in her recall. Once recall is consistent, keep it sharp by using randomly to ensure it will work when needed. (Recall to short circuit unwanted behaviour, like eating poo, barking, wandering etc.) Good luck.

Après avoir essayé plusieurs sifflets pour chiens, je peux confirmer que c’est le meilleur que j’ai testé, et le retour marche très bien au départ avec une récompense, qui a beaucoup de valeurs pour le chien, et ensuite plus besoin. Je le recommande

The Acme 211.5 is not silent. It is an audible to human dog whistle without the pea. The 211.5 runs about 5700 hertz and is audible to a dog at an advertised distance of 1.5 Km, or around 1600 yards. Just under a mile. I use this whistle while duck hunting. My dog hears it just fine if I need to handle on long retrieves. It is a good product that is consistent in its sound quality.

compre el producto pensando en que me serviria para huyentar a los perros, pero me ha funcionado para adiestrar a los perros de casa y ya con eso sali ganado

So easy to use that my 18 month old can whistle up the dogs.
