Dogtra 1900S Anti Bark Collars for Dogs – High Output Electronic Dog E Collar - 3/4 Mile Range, Waterproof, Rechargeable, Adjustable Levels, Vibration – Obedience, Hunting, K-9, Stubborn Dogs Training

Product is great! Dog really responds to it well. Sent via UPS who ignored signs to close gate behind you. Left open and dogs ran away. Luckily we found them but really not cool.

This e-collar has a wide range of frequencies to manage your dog's behavior or their safety. With a vibrate, static shock and 10-second sustained shock level of 1-120 it is good for medium to extra large breeds. We are very happy with spending the money on this product.

Our dog trainer uses this brand and so it’s what we ordered and I understand why it was recommended! Love that it has more levels to work through than other e-collars. We have a German shepherd-husky mix and he is stubborn but this worked a lot sooner than the cheap collar we tried before. I also love that Dogtra has great customer support and free training videos on theirs website for you to watch. 10/10 for sure!
