do they actually work ? next door keeps 2 russells that they leave out right by my kitchen window about 6ft away with a small wall between us, anyone walks past and they go bananas barking and its driving me insane, they don't even come out to try and shut them up, I asked the wife if she could move them cause they got a big garden at the back, after a massive argument her answer was that I should shut my kitchen window (in this heat) and that she doesn't give a f**k were her words !! my daughter cant do her homework at the kitchen table cause she cant concentrate so she goes to my parents to study, to top it all off I come home today and they've only gone and bought another russell pup !!!
