Billy is a border collie, he lives on a boat moored just along from us.
He is a rescue like Beano, unfortunately Billy can be a bit unpredictable.
Billy and Beano are fine with each other usually but occasionally Billy barks at me and Beano doesn't allow that!
Billy has trigger words that upset him and make him aggressive, in fact he has a whole bloody dictionary of trigger words.
Including, hello, good boy, sit and stay!
