Review on 🐶 Dive into Effective Dog Training with ACME Dog Whistle 211.5 by Tammy Chavez

Whistle is plastic but sturdy. You hear it, but it doesn't hurt your ears like a coach's whistle in gym class. I suspect it sounds louder or different to the dog. When I first used it, my little Boston came running from afar. He's been trained to get close to a human whistle, but I can't whistle loud enough when he's far away (we live in a village on Tomorrow). I was pleasantly surprised that this did not require any additional preparation. I took a second one just in case.
