I have a new 15-week-old dachshund/chihuahua mix. He can sleep through the night for 6-7 hours in his crate without an accident. However, his crate is in the living area, and sometimes my mom or her fiance will get up in the middle of the night to get a drink or go to the bathroom, and this will wake up the puppy. Should we then just leave him and let him bark until he goes back to sleep? Or will he have to be taken out when he is woken up, because of how young he is?
