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!!!

I’ve owned one similar but it was cheaper and broke. This one is rechargeable which is amazing, I use the sound and vibration my dog is very vocal, cries whines and barks. When she sees a dog she nonstop barks even if I try to distract her and give her food so this collar makes her stop that behavior. I don’t even need the collar on 24/7 as long as it’s around her neck she doesn’t bark but when it’s off she’s smart and barks. This definitely works but be careful if your dog is like my dog she’ll make noises to annoy you but trick the collar into not beeping!...

My dog used to bark at night when a neighbor's husky started crying, I bought this collar so I dont have troubles with my other neighbors, I didnt have to use shock mode, I just enabled the sound on 3 and the vibration on 3 also (for medium dogs as the instructions suggested), at first my dog got distracted with the sound, and tried to find where it came from, after some vibrations and barks he understood that he is not supposed to bark at other dogs, now I can sleep at night without waking up because of my dog....

My puppy has separation anxiety and will start crying and barking when I leave. This has actually cut her barking way back. You can hear that she starts a bark but the sound and vibration deter her (it must be those two at the most because after the second attempt at barking I don’t usually hear her anymore, and the collar is designed to escalate with continued barking from sound deterrent to vibration deterrent to shock deterrent). I don’t think the collar has ever had to shock her. And I’ve never heard her yelp with it either. And I can say I haven’t heard these things because I watch her sometimes from my security camera after I leave to see how she acts....

This bark collar is amazing. Worked on the first day. We love pup but his bark is one of those barks that make you jump and scares one of our son's to the point he cries. We have been through two other bark collars and a bark box. So nice to finally have a product that actually works.
