Dog No Bark Collar for Bark Control with 7 Levels Adjustable Sensitivity Control, Electric Anti Bark Shock Collar for 15-120 lb. Large and Medium Dogs

Works great on a two year old boxer. I take her to a friends house on the lake and she would bark at the boats going by, it was totally annoying. Every now and then she will bark once and the warning tone sounds. After that she is usually good for the rest of the day. She went from barking every ten to fifteen minutes to barking twice in in eight hours. Best part about it is she does not even get shocked anymore, because she is smart enough to know that warning tone means quit barking. LOL

I purchased this collar for my Shitzu who barks incessantly. Unfortunately he is still waking me at all hours because the device does not work at all. Checking other reviews I can't make sense of why some work and some do not. But if you truly need a collar of this type, spend a little more for better quality. I have had this less than a week and after posting this review I will go purchase a different collar.

So far this is a great training device. I have a small dog who drives us crazy with his barking. We have tried all different kinds of 'No Bark Collars' priced anywhere from $15 to $100. This works better than anything we have tried so far.I highly recommend this. Our barking problem was quite severe and now all we have to do is place the collar on this old-stubborn-lovable dog and he doesn't attempt to bark. One or two beeps to warn him of what's coming is enough and I never ever thought it would be.This is the sixth collar we have tried and it works the best for us...bar none!!

Worked great for about a day. I ordered two collars. One worked about two weeks before beeping and shocking randomly while the dog was quiet laying down. The other unit was on a different dog and worked for one day before not going off at all when the dog was barking. The collar still beeps when you adjust the sensitivity, which is all the way up and still unresponsive. We even ordered new batteries to see if maybe that was the issue. Not happy at all.. Spend the extra money and get one that actually works.

Quit working after 2 weeks. Was doing the fast clicking and the only way to stop it was to take the battery out. This is an odd sized battery so don't bother trying to find it in a local store. Which the description doesn't even list the battery size so it becomes a guessing game and the battery that was in it doesn't show it's size. The 100% guaranteed satisfaction is a joke. The description doesn't have at time frame so when you email them low and behold I was JUST OVER.

It stopped my yappin lap dog from yappin unnecessarily. Don't leave it on her, but when people are coming by to have dinner, she goes to her crate and wears it. I tested it on myself before her and it does bite on the higher levels, but lower levels it just kind of gets your attention. Just wish it didn't have those oddball batteries that you can't find but on Amazon.

One star is being nice.This is the 4th collar I've purchased.... it didn't work my dog would bark and bark and bark and whine so loudly yet the collar would do nothing, then he would bark just once and it would shock him. Right out of the box...so got a new battery still nothing unless he only barked once..... what good is that?

Terrible. Didn't work at all. Messaged the seller and got training info, but it still didn't work. My dogs are short haired and it was on correctly. It would beep when I adjusted the volume, but did absolutely nothing when they barked. No beep, no nothing. The tester indicated that it worked, but I'd listen for the warning beep when it was on and they were barking like crazy and I never heard a thing. DO NOT BUY! Price has dropped from $19.99 to $12.99 for a reason.
