  1. Talk2me

    Thank goodness! Quiets her down which is fantastic! Takes a few barks to kick in, but it definitely does work so far & its been A month or more & still works. She doesn’t appear to mind wearing it either. Not that big, so it’s a great size for little dogs.

    I’ve got to tell you about this bark collar. It’s been a game-changer! We used to struggle with her barking at everything on our walks, but within a few days of using this collar, she almost stopped barking completely. After a couple of weeks, she’s been super quiet. The only downside? The battery life isn’t great – it lasts just a day or so. But honestly, I don’t mind the frequent charging when it works this well. Totally recommend it if you’re having the same barking troubles!

    The collar was everything they advertised! I have wasted so much money on useless and bulky collars for my little barking chihuahuas. This collar is thin and works perfectly! I’d love to get more and give them to my neighbors!! Lol

    Per-safe is the perfect size for our Maltapoo who is 9 pounds. Works better than any other we have tried. Highly recommend.

  5. NaughtiLiterati

    Since we began working from home, our chihuahua is a lot more excitable as he protects his humans and just overall happy to see us there. That was great, but didn’t really help with meetings or conference calls. This collar gives him a gentle reminder that silence is golden.

    This has been a great tool for our dog. The battery life holds for a long time, the vibration works but isn’t too much, and the charging is easy. Great quality!

    My dog’s bark is so sharp and ear-piercing that it will make me jump every time! I decided I had to get it under control. This collar definitely detours the barking! It’s easy to charge up and the charge lasts for a long time. It’s an adjustable collar that is best suited for smaller dogs. It’s easy to use because it self-adjusts depending on how much your dogs bark. It performs better than other similar collars because it has so many different settings and ways of stopping the bank.

    We currently have a small mini pincher who has a very large voice to say the least. Every time the doorbell rings or someone comes to the door, the barking starts and it is loud. I was looking for something that was small and humane for her and traditional bark collars were something I did not want her to wear. When I stumbled across this one, I decided to give it a try.What I really liked about this particular bark collar was the different settings it allows. There are ten different settings that can be set on the collar and it also gets to know your dog’s voice and bark pattern. The collar itself is extremely small and probably the smallest bark collar I have ever seen. It has helped since he has been using it and I feel my dog is getting adjusted to it which is nice to have some quietness again.

    This PetSafe NanoBark Collar just gave us our first quiet walk in about two years! Rory may look innocent, but she barks at everything that scares her. Even airplanes. And we live along the flight path for a major hub. We have two other rescue pups that are more quiet, and they generally follow her lead.We put the collar on in the house, and she barked soon after. Then she shrieked. It really scared her. That happened a couple more times and then she stopped barking. She didn’t bark even once on our walk. We did get lucky, and we didn’t run into any of the dogs that she usually barks at (just a friendly dog who is huge and she usually plays wildly and loudly with him). She was so quiet. Towards the end of our walk, the collar made her yell. We had not heard her bark, so we aren’t sure if it went off wrongly, she was starting to bark, or some other noise/vibration set it off. Either way, we’ll be paying attention for that. For now, she is behaving so well. This collar may be helpful even if used for very short periods of time. I hope it continues to be this effective. Recommend!!

    This PetSafe NanoBark collar works very well. It has a static stimulation that progressively goes up if your dog continues to bark. It starts out at the lowest level and continues to go up until your dog stops barking, then the next time they bark it will start out at that level. If they stop barking it will start out at the lowest level again so it’s a very effective way to correct barking. It works better than any bark collar I’ve used and it doesn’t hurt my dog. The collar is very small and is comfortable for my dog to wear all day. Great working small profile bark correcting collar.
