We got this yesterday, and my husband used it on our dog and he said it works just perfect. Our dog sometimes is very hard headed so yesterday when my husband use this whistle he said our dog Rowdy came up him right away. I high recommend this whistle, you can put it on your key chain and the size is just perfect. Our dog Rowdy sometimes like to wonder around our neighborhood so now that we have this whistle she listen a lot better. This is highly recommend product, if you buy this now the price is such a great deal.
