I live in a 2nd floor Apt. in a private house, the owner of the house just next door has the dog and actually gets the dog to bark { she's a little off the wall ) ,
Anyway ,
I 1st purchased a simple whistle that did work,
However.
I got tired of having to use it several times a day....
I have this Dog Silencer Max sitting in between the window screen and my window {2n floor} and thankfully I'm still able to use the AC cord and still be able to fully close the window !
the dog is as quiet as a mouse and I couldn't be happier !!
