dog whistles?

Question

what r they actually for and is it an idel item for training ?

Answer 1

They are a high pitched whistle that only dogs can hear (or animals, I'm not sure). But humans cannot hear them. Some people use them, but I wouldn't. My vet said that the pitch of the whistle hurts, so the dog pays attention. A regular whistle or a clicker would work just as well for training.

Answer 2

We use whistles constantly with our retrievers in the field.
Fundamentally a single blast on a whistle means sit, and a trill means recall. Through the use of the whistle and hand/arm signals we can cast the dog to any given spot that we want (where the bird is laying on the ground)
The Gonia whistles are the standard.

Answer 3

At one time they were used by shepherds to summon the dogs without startling the sheep with a sudden sound, but over time they'be become a devise to annoy neighbor dogs. You can use it for training if you wish but be aware that some whistles sound to them like feedback sounds to us.
