I researched and decided to buy the A+ trainer to train my pomeranian puppy (9mos) to stop barking constantly. Once received, the unit was easy to charge & program. I purchased this device because of the control ability- I did not want to use a shock collar. I was able to program beep and vibrate only. Within 3 days of wearing the A+ unit she barks 95% less. When she barks it's a single bark or two vs the repeated 5-10 minutes of barking.

I have a dog that barks constantly at people who are visiting and any little noise. nothing would stop her. The moment we put this on her she was a bit scared but quickly realized it was her bark causing the vibration and sound and stopped. now we put it on her when people are visiting and she is quiet. It also seems to be training her when it is not on because she only barks about 15% as much ash she used. This is a great easy to use product, set your levels, find a size for your dog and put it on. Enjoy a quiet home. ...

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.
