Review on Collar Upgraded Anti Barking Vibration Medium by Megan Gardner

Bought for my Husky/Gold and my Great Pyrenees/Maremma. One worked right away while I charged the other. Our Pyr is naturally a very large barker by nature, she only guards our house, no livestock. She only wears it at home and during the day because her barking will scare everyone while we're away and at night. Our other dog only barks when ours does, but in a very hoarse voice. I've set them to only vibrate (Pyr @ level 6 and Gold @ level 4) and that's enough to do the trick. Has short ridges that rub against hot spots or sores on the neck. Fits my 30lb and 90lb dogs with extra fluffy coats and has enough room. Also great is that I don't have to buy spare batteries, they charge in about 1 hour with USB (you get 2 in the box, 1 for each charger) and on the other end they have a Samsung phone charger. Will be updated in a few months. At the moment I highly recommend it.
