    • Lightweight & great for very small dogs
Most bark collars are too heavy and too large for a small dog. This one is light weight & works great for my small Cavapoo who is 8 lbs with a small neck. I don’t keep it on all the time. Often if she barks I tell her I am getting the collar & she stops barking.

    • Shocking experience for my poor pups
This collar never seemed to work correctly. The last straw was when it decided to start shocking our pup out of no where and would not stop. I had to grab it and hold it to get it off my pup. Do not recommend. The size is great for small dogs. But I would never run this without being around.

Review Image by Kerri
Ok. I can’t say enough about these for our two small dogs. We have a Miki and a mini dachshund…..both big barkers! This has been life changing for us all. We can sit on the porch other dogs, neighbors even workers can go by or come in the yard and they do not bark anymore. Took 1 day to make a difference and I’d say by day 3 we were all very happy. They can be outside and not barking at every little thing. To be honest I think they’re more at ease now, just relaxed and enjoying everything not on alert and ready to attack. It’s wild. Our cleaners asked if we had them professionally trained bc from one week to the next they couldn’t believe it. So for us 10 stars. Already recommended to friends ... show more

    • Bargain
Corrected my dogs behavior in one day. He’s not fearful of it and actually insists it’s on before going outside. Very low profile for a small dog. Highly recommend.

    • DO NOT WORK
I ordered three of these for our 10lb dogs. They are one-finger snug, and do ABSOLUTELY NOTHING to stop our dogs' barking. They are fully charged. I've tried loosening them and tightening them. Nothing works on any of the dogs.

    • Controversial collar
We recently got a puppy who was barking at everything and trying to bite the little ones due to the frustration. I know that they take patience but I also needed to take over control and as much as everyone else fought me and didn’t want to put the collar on the puppy I showed them that it was not harming the puppy. We honestly only used it for a couple of weeks and the puppy learned quickly to yes bark at the door when the doorbell rang but not for very person that passed by when they were in the backyard. She also stopped trying to bite and has been very patient. So for what it’s worth it worked without harming the dog and she never once cried or helped. ... show more

    • Works well for my 9 pound dogs
These are small enough and have worked well for my two small dogs. The battery charge lasts about a week. Minor gripes: The proprietary charging cord is short. I’ll need a usb extension cable. The flashing LED is insanely bright in a dark room. I used some dimming stickers available on Amazon to help. ... show more
