Review on Hipat Whistle, 2 Packs Plastic Sports Whistles With Lanyard, Loud Crisp Sound Whistle Ideal For Coaches, Referees, And Officials by Adam Cummings

Use this to summon the dog & carry around for me as a safety device in case I fall when outside. The price is good & I keep purchasing so I have enough to have one in each coat pocket and also have one to carry when I am not wearing a coat or jacket. The dog was taught to come promptly when the whistle blows as I started with her when she was a little pup [8 weeks]. Always used the whistle when I called her to come; now it is automatic for her. Essential for living in a rural area. And they are plastic, so not too cold in the winter when it is icy. I have 16 acres & the sound carries well.
