So nice that people remember me. Yes I have 2 baby cavaliers, and they are not barking (YET?). The nuisance barker is my Maltese-Shih tzu girl and she is mature girl. She really barks at nothing. I mean maybe she hears something to bark at, but I could not hear or see what she is barking at.
A few times a day she looks in a random direction (bushes, fence, veg garden) and starts barking as something horrible scary is in there. I usually come and check what she is barking at, but can't see or hear a thing. She can carry on for quite a while barking and barking. When I am at home, I can't stop her by growling "No". I have to take her somewhere where she cannot see what she is barking at, and then she quiets down.
I have to be away from home for some time every day and I do not want her to disturb my neighbours. They did not complain yet, but when I ask them whether she is barking, they answer positively.
As I have 3 dogs now and might need a collar for one of my Cavaliers in the future, I thought it would be a good idea to buy one.
K9force site also mentions that we should check whether collars allowed in our state before ordering. That's why I would like to find out why some authorities ban them.
