Fantastic
Our 11 month old pugalier decided to take up barking as a hobby and we tried everything to train her to stop to no avail. We were told to try the citronella bark collar by a friend who had the same issue. I ordered it, it arrived super quickly, I followed the instructions and after scaring the hell out of her the first time she sprayed (I felt awful but comforted and distracted her and she was fine soon after), she made 2 more barks in the next day or so and then stopped completely.
After about 4 days I didn’t put it in at all as she wasn’t making a sound. It’s been about two weeks now, i’ve put the collar on if I sense she’s on the edge of barking (but that’s only been a few times). Fantastic. Best money we’ve spent on our pup.
