It's a bit big for under her neck but it works and has helped so much... living in an 5 story apartment building with too many rules and thin walls my dog barking was a big stress and now I can relax. She'll stop barking after one maybe two barks and stops. I take it off her immediately when I'm home but she has learned not to bark so much. I've tried so many things out there and this helped the most.

I purchased two of these. One works perfect, but the other one doesn’t work. I tried testing it multiple times (at least 20) and it only worked correctly once. I adjusted sensitivity, but nothing seemed to make it work like it should. UPDATE!! Seller reached out to me and promptly offered to send a replacement! 5 stars for customer service!

Great barking collar and adjustable for my little 8 lb Pomeranian. Alot of collars don't fit him but this one does. The extra pieces we bunched and rubber band on the side out of the way with small clear hair ties. The sound and vibration alone distracted him and works on cue. We set the sound on 7 and vibration on 7 and shock on 1. Some collars go off when he shakes but surprisingly this collar doesn't. Worth it.

I have tried several collars in the past, remote style and without...this is the best one yet. I have a 90 lb dog who loves to bark and the level setting for shock is great. Depending on our location, it is easy to set, stays in place, lasts long and is effective. The collar is soft and durable and couldn’t be happier. The options with this collar make it easy to change with your dog and is easy to use. Will refer to our friends and family.

I have two very large breed Italian Cane Corso pups over a 100 lbs and they were always barking at the neighbors. So I got the collars and set the vibration on high at 6, the shock at medium on 4 and the sensitivity at medium on 4. It worked fast but they still barked but only once or twice at first. I have tried the shock on my self at 4 and it was like the trick gum zapper. Anyway it's been a month now and working great. Now I have turned off the shock and left the rest the settings the same with good results. Would recommend....

I have two MalPom Male brothers and I tried everything to get them to stop barking and had to return everything because in a matter of a few days they would get use to the product and I would have to return it, I tried this collar and its been almost 2 weeks and when I put them on when I go to work my boys don't bark anymore, This collar is a lifesaver!!!
