I am probably going to be adopting a rescue dog in hte next few months and am starting to get stressed about daily life with a mutt! It won't always be possible to walk the dog at the same time each day. e.g. we are not up and out at the same time on weekdays as the weekend. School holidays are obviously different than school days etc. Wil this matter? Wht about sleeping? Do you have to constantly interact wtih them if they are awake? If they fall asleep early evening will they still sleep all night? I know all this sounds pretty stupid but I need to know! Many thanks
