Don’t waste your money however cheap it seems ### 1/5 — Does not work at all *2021-09-16* Don’t waste your money, it doesn’t work. I stood 1 foot away from the barking dog on the other side of the chain-link fence with this thing on full blast but the dog just barked right over the sound. what a joke. ### 1/5 — My dog still barking *2020-02-05* Very simple app, only stop and start, obviously as human I can’t hear anything. I don’t think my dog can either, cause he hasn’t stopped barking. Made no differences ### 1/5 — FAULTY APP *2020-01-07* Freezes up on my phone each and every time I use it. On the few occasions that it did work, my pup was unfazed by it. ## Frequently asked questions about Ultrasonic Dog Whistle Pro ### What is Ultrasonic Dog Whistle Pro used for?
