This collar has solved the problem of my dog barking outside at every person, car, and neighbor’s dog. It’s such a relief. I tried a few other options from Amazon and this one for a two-pack was the best price and works great. The battery lasts around 2 weeks at a time, which I can hardly believe! Another one I tried needed to be charged almost every day! Try this one, I don’t think you’ll be disappointed.

These collars worked as soon as I put them on 1) 10 lb. Chinese Crested Puff and #2) 35 lb Pitt mix. These little lovies were running across the deck barking at the squirrels especially annoying late at night when they thought they heard something. I don't leave them on all the time, just when they begin the behavior again. It seems to humble them but they don't relate this to me. I use the vibration on 2, and the shock on 0 for the Puff and low for the Pitt. I do recommend.

They work but sometimes when my 1 dog shakes her head the ears flapping set it off. I’m not happy with the shock part. I tried it on myself & it did hurt but my 1 dog likes to set it off. So I just keep it on vibrate & that does the job to stop the barking & jumping. It’s worth it if you use it properly. Now they see them & I don’t have to turn them on all the way. It’s worth the purchase just beware of the size of your dog & test it on yourself 1st so you don’t hurt them please.

They hate me because these collars work! I received a complaint about my dogs' barking recently and had to resort to buying these. The collars give options for just a sound alert, vibration alert, or a shock alert. All I had to use was sound, and you'd think I had severely punished them. They hid from me all day long, making sure I knew they were upset with me. But even when I walked them after taking the collars off, they at least remembered that something negative would happen if they bark. I just received them two days ago, and not enough time has passed to really get a feel for the full effect, but so far I LOVE these.
