Review on 🔇 Ultimate Solution: BIG DEAL Anti Barking Device - Rechargeable, Mini Safety No Barking Bark Control Device by Tara Hammack

Tried this stuff on several dogs of different sizes and nothing. Well, I take back my words. The smallest dog I tested it on bowed his head as if you were asking her a question she didn't understand, and that's when he was at "3" or the highest level. I left it charging overnight and tried all different frequencies from different distances including 20ft to basically tie it to a dog collar and the barking didn't even slow down. I do not recommend it to anyone.
