Bark Collar, 2 Pack Rechargeable Dog Bark Collar for Large Medium Small Dogs Training Collar for Dogs with 4 Adjustable Sensitivity Dog Barking Control Devices Dog Shock Collar with Beep Vibration

These might work for a small dog but my big rough collies did not stop barking! It didn’t phase them at all! I also noticed that when one of my dogs would bark, the other one would get shocked. I ended up returning

So I have 2 dogs that I bought this for - a brother and sister - and though they are friendly, whenever they would see a dog walk by our house they would go nuts barking their heads off! That is when we would warn them if they didn't stop barking we would get out the naughty stick (rolled newspaper). Never worked and they would get so excited they would start fighting with each other. So finally bought the collars - best price for the package of 2! and set them up. Instructions weren't quite right but finally figured it out (not sure what the non-power button does). So now when they start barking I put the collars on them, which they do scratch at (my dogs only wear collars when I am taking them out) and wait for the next incident. If they start barking again they get a mild shock and vibration and beep (so we know its working ) and they do a little shake and ? (hard to describe), and immediately stop barking! No yelping in pain or apparent discomfort, just seem to be distracted by it. The system works by increasing the frequency and strength of the static "shock" and vibration if they continue barking . My dogs never have. For their 'good behavior I take the collar off in an hour or so. My hope is the act of putting the collar on stops them from barking without the need for the vibration and static shock and then them just not barking under those circumstances again. It has been a swift and effective deterrent to their almost manic barking! Couldn't be happier with the performance of the product. It would have been 6 Stars had the instructions been better and an explanation about a good working process for training was included, but in fact the device is self training, so once you charge it, set it up and attach it works!

It worksOnly thing the lights confused meI want a simple red light it’s working and that’s itThere are many optionsI have German Shepard’s and it nipped the barking as soon as they were out onLast very longI would say these are amazing for the price

I waited a couple of weeks after ordering and receiving the bark collars to make sure they were going to hold up. Good news! These are working so well for our stubborn pups. The different settings for different dogs is handy and for different levels of training. Our male heeler/ shepherds are 2 years old and have some behaviors when people come into the house. The automatic beep and vibrate secondary is a great reminder for them to get quiet when we have guests.

Collars came nicely packaged, slim design is sharp looking and the collar itself is pretty durable. I gave 4 stars because it is a bit confusing to program, you are given 2 buttons and colored lights to program with and hope you set it to the right one. I have two 2 year old 85lb Newfoundland/American Bulldog mix dogs with BIG necks... I ordered the biggest size and my guys still have approx 2" left on the collar. Charges quickly and battery last for longer than expected. I use it on them when nobody is home, as they balk at everything! It functions properly for what I needed it for, they get one bark and a warning before the shock is applied... So far all they require is the warning and they stop. I'm happy with the product, you cant beat the price for two collars... I hope it lasts!
