I have a 7 week old puppy. I know...I really shouldn't have had her until 8-10 weeks, she was a rescue. At what point or age is it okay to leave her home alone? I could probably get a neighbor to let her out midday, she sleeps a lot of course (under my desk has been sleeping since 8am and it's a little past 11 now). I have been looking into pet sitters and such and unsure how long I will need one.
