She'll suddenly show a great interest in escaping and wandering too , however much of a home body she has been before ! One of my bitches is in season and has added an annoying feature to that. When I leave her she yells her head off, disturbing the neighbours.She has suddenly started this odd behaviour. At first I thought that she was complaining that she was not getting a ride in the car or taken out every time, and so she'd stop after a few minutes once she'd learned that her demand would not be met. Too easy: I realise now that the dog, her past mate, is kept at my other address in the village, and her complaint ,and her ambition, is rather more basic !!
