Does anyone know much about dogs. Our dog explodes with a fit of barking a few times every day, usually when she sees the neighbours cat, or a particular car passes on the road. It is always annoying, but one of the family has started working nights and now it is becoming a real problem. None of the usual causes of barking seem to apply, the dog isn't left alone, is walked regularly etc. I think she just enjoys the excitement. But its driving me crazy.
