Most training schools acknowledge the benefits of using a whistle. This whistle has a pitch that can be altered to suit both dog and trainer. There are several reasons why whistles are wonderful training tools for dogs.
Firstly, whistles can be heard more clearly than the human voice, particularly on windy days. Unlike the human voice, the whistle will not convey panic, frustration or weariness and so sends an unambiguous signal your dog will not struggle to understand.
