We are getting a Miniature Schnauzer and i am home during the summer but when i go back to school in September i will leave at 6:45am and get home around 3:00pm. My parents leave at 7:30am and are gone all day at work until 5:30. It is not possible for my mom to come home on her lunch but my dad could once in a while. My brother will be here everyday until 3:00pm then going to work. But he is moving out in a couple of years. I am not sure if my Miniature Schnauzer will be ok home alone for that amount of time a day?
