MinnieMe2,
Our dog is a cocker spaniel/sheep dog mix. I've been told that cockers are frequently "barky".
My concern is that she seems to be getting worse. If she were a puppy, I'd figure it may be a behavior she'll grow out of, but since she's eight years old and really just started getting bad within the last 18 months, it makes me wonder what's going on.
I've tried throwing a nerf football at her when she barks, but she's often in another room when the barking starts and I doubt that she would connect the barking to the consequence if I were to throw the ball well after the barking starts. Also, as soon as she starts barking, she heads to her room in the basement, which leads me to believe that she comprehends that the barking brings consequences, but she has taken measures that allow her continue barking and avoid the football.
The citronella collar intrigues me. She couldn't get away from that!
