DT Systems 190DT No-Bark Collar Waterproof Lightweight Durable Barking Control Trainer for Medium, Large, X-Large Dogs, Vocal Cord Vibration Sensor, 9 Adjustable Stimulation Levels

Love the ability to change the amount of charge for different dogs. Great to be able to just change a 9 volt battery so easy and lasts a long time. cheap battery, but with lots of power and lasts a long time.Without a doubt the Very Best Bark Collar.....

This worked very well. Our mastiff stopped barking at everything. Now she only barks at the collar when we take it off lol.

These work great. I love that you can adjust the correction levels. Our young male lab needs it dialed up higher than our mature female lab.

I have a Doberman puppy who loves to guard his yard. I have tried other dog collars and he is simply too stubborn and will get used to the vibration or shock level and ignore it after a couple of days. I purchased this because it was recommended to me for very stubborn dogs. I followed the instructions and started the setting low and would gradually increase every time he could continue to bark. The collar is so inconsistent that I got the collar up to level 9 and went off sporadically. He was screaming and shaking and now refuses to go outside in his yard because he has no idea what caused it.

Collar seems to keep dog quite most of the time, but easily gets turned and does not work. We think dog is getting shocked whenever he get near underground electrical lines.

If you have a large long-hair dog this is the the bark collar that works.

Fit's my 5-11 bag well.

This Trainer collar works, but not well on our dog. Maybe its because we have a Mastiff. She barks right through it. I have turned it all the way up and it doesnt really bother her. If you have a big dog I would try something diffrent
