PetSafe Vibration Bark Control Collar for Dogs, 10 Combinations of Vibration Correction

I think the negative reviews below aren’t really warranted. Just like any dog toy or food, each dog is so unique that not everything works universally. We’ve been using it for a week and the vibration does deter our puppy from barking nonstop. I worry that he may learn that he should only be quieter when wearing this collar and I do wish there was some way to do adjustments on vibration settings. There were a few times it vibrated when he sneezed or was rubbing himself along the sofa and I was not very happy about that. Overall his barking is more than cut in half and we are continuing to work with positive reinforcement to reward his silence. I’m waiting until the 45 satisfaction guarantee period to determine whether or not it is a success for us. I do wish this one was rechargeable.
