Itâs recommended that four hours is the longest that dogs should routinely be left alone for. Every dog will be different, dependant on how old they are and what they are used to. For example, four hours would generally be too long for a very active, young puppy.
Ages 11 - 12 should not be alone longer than 3-4 hours. Ages 13 - 15 should not be alone longer than 8 hours. Ages 16 - 17 should not be left alone longer than 12 hours. All this being said, there actually is NO LAW as to the proper or legal age of a child being left alone in Indiana. Home AloneI don't think it matters where you live but a chid has to be thirteen to stay alone and that's only four hours you have to be sixteen to stay alone a whole day or anything.   Legal AgeThe age at which a child can be left at home alone is only legislated in two states, Maryland and Illinois.
