Review on 🐶 STOPWOOFER Ultrasonic Dog Training-Bark Control Device for Small, Medium, & Large Dogs-Dog Bark Deterrent Device- Anti Barking Device up to 16.4ft Range-Safe for Humans & Dogs by Mary Jones

Restrictive woofer was very effective on our anxious pup and immediately caught his attention. I no longer snap at him if he lands in cat food or a trash can. At that point, if he just sees it in my hand, he'll take it as a warning. (I had it for two days.) We used it to bark and keep him out of trouble around the house. I still have to spend some time watching YouTube videos, but I've seen improvements so far. The only thing I would like to improve is maybe the volume (though not by much). Such a faint sound (it seems louder to our dog), but sometimes almost inaudible. (Though of course he heard it... It puts him off when he eats cat food.)
