Review on 🦜 Effective Ultrasonic Anti Barking Device for Outdoor Bark Control - Sonic Birdhouse Bark Deterrent with Dog Bark Control by Daniel Ogbebor

I was very disappointed. Got it for our Chihuahua but it caused my German Shepherd/Husky pain (I mean pain). Almost immediately he started acting like a maniac, but he didn't know why. He was acting so unusually that we took him to the veterinary clinic (this was after his veterinary clinic closed). When we went there he was fine. So we went home. As we entered the yard, he went mad again. My husband, not knowing he bought it, asked me if I had done anything else with him that day. As I thought about it, I remembered having this device installed. We immediately turned it off and removed the battery. My big boy started acting normally. A few days later my husband (after I asked him not to) tried again. Almost immediately my big boy started acting crazy again. I suggest only using this if you hate dogs (and seriously, even if you hate them, DO NOT).
