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 Carrie Porter

My dogs are small so the collars are too big, even the smallest ones I could find. This is a magical alternative! My dogs both responded well to it. And I noticed a noticeable improvement in her behavior when barking [or NOT barking]. Not perfect, but we're getting there. My old dog won't hear an ultrasound but will respond to a normal beep. This is actually ideal because the youngest dog who hears the ultrasound barks the most. The only thing I didn't expect is that my cat hears it too and it scares her to death! Perfect size device. And I have an orange one so it's easy to find if you need it! I don't use lace. In my opinion it seems a bit short so I'm not sure I'll use it anyway. The fact that they say up front that it doesn't work on all dogs and that it can be returned made me feel like this was a reputable company.
