This collar is the perfect humane (vibrate only) automated anti-bark collar. We have a medium-sized Havapoo who recently discovered the curtains on the window facing the road open up where he can look out into the world as much as he wants.However, he got in the habit of barking loudly at anything he spotted that alarmed him. He's not been the easiest to train so I knew teaching him "Quiet" or anything like that was going to be difficult. Whenever he started barking, one of us would usually have to get up and close the window curtains and occasionally he wouldn't settle back down and we'd have to put him in the crate. He loved spending hours by the window watching the world while I did things around the house and it offered great entertainment for him where I wasn't worried about him getting into anything as well. But as his barking spells got worse, we weren't sure how long we could deal with it without losing our sanity ?That's why I'm so glad I found this collar. The second he does a loud bark, it beeps and vibrates and he quiets down immediately! (And he usually stays quiet too after that - unless there's a dog outside, in which case, he switches to whines/ growls which we're chill with ?). It doesn't set off with his quieter woofs either which is fine with us since the little woofs are kinda cute and are good to alert us that the mail is coming or things like that.Notes: the sensitivity levels have worked really well so far. We usually leave it somewhere around 1, 2, or 3. Haven’t had issues with the TV or other external sounds setting it off really. It did go off once though when I was holding our dog in my arms and shouted for my husband - I’m guessing because I was too close to the collar. We just lowered the sensitivity down and it’s extremely rare that anything happensTbh recently our dog simply wearing the collar is enough to deter him from barking. Often we don’t even have it turned on and he has no idea and still stay really chill. He’ll growl at things that he wants to bark at sometimes but that’s about it nowWhich this ended up making it wayyy easier to train him on things like “quiet” - we were able to easily learn some of his triggers. Then when those happened, it was way easier for him to become more quickly composed in response to our command and get a treat!Battery life has been great so far! But we don't leave it on our dog all the time - usually he just wears it when we're both home and he wants to sit in front of the window or if my husband is going to play a video game that has monsters/ wolves which our dog would frequently react to seeing or hearing ? He can now happily stare out the window to his heart's content though and we don't have to worry about needing to figure out how to stop the barking spell or hold him to try to get him to settle down.I’d say that 2 weeks is a pretty accurate battery life description. He’s had this one which he just wears for a few hours each day and it’s probably been at least a month or so since I actually charged it last ?TLDR: Overall great product. Humanely stops my dog from loud barking spells. Doesn't vibrate for growls, whines, or very quiet woofs. We very rarely had any issues with the collar being set off by anything other than him barking.Our home is peaceful once more - thanks for a great product!Update: had misplaced the charger, but my husband found it! ? Just search for 2DC / 2mm barrel jack cord and it should pop up. You can also search "Charger Replacement for Dogrook Bark Collar" and that should populate the one that is specific to this item. I have no idea why they don't have this listed in the product information itself, but hope that helps for anyone else that loses the charger!Edit to the update: looks like they’ve now added an additional link to the charger replacement! Little late for us ? but glad they’ve added it now!
