Hello - Im new to the website. My Maremma Sheepdog is 13 and a half. In the last 2 months she has started messing the house, in the living room at night time. We feed her once a day around 5pm and she always asks to go out to the garden straight after her dinner where she has a number 2. We are out of the house in the morning so it's not as if we can feed her earlier because presumably the same thing would happen while we are at work. 4.45pm is the earliest we can feed her. She never used to do this - is it a sign of old age? And does anyone please have some suggestions. She doesn't do it every night, but probably 2 x a week. Thank you. Emily
