Bark collars

I have a 3 yr old female basset that barks all the time when she is outside. Even if I’m outside with her, she still barks at what I can see is nothing. Of course she can see and smell a whole lot better than me so she must find something interesting to get her attention.

I got a text from my neighbor this morning asking if I can do something about her barking because his daughter’s room is next to my fenced yard. I did say I will keep her in from 9:30 at night to 6 in the morning but there might be times that she needs to go out in the middle of the night. I’m going to keep her on a leash during those times so maybe she won’t be so annoying to them.

My question is how many here have used a bark collar to help quiet them down so much as not to disturb your neighbors? I’m considering getting on from Amazon and if I do, it will not be a zapper one but either a vibration or electronic beeping.

Any feedback will be appreciated, thanks!
