Single puppy parents: how are you leaving the house?

Hi all, my puppy is 13 weeks old. My question is pretty straightforward. I know you’re supposed to work them up to separation gradually, but that can take weeks and months…everything I read says if you leave for too long too quickly they can develop separation anxiety.

I absolutely HAVE to go to the DMV and to a doctors appointment this weekend. So wtf do I do? I’m living in a new city and don’t have anyone I trust to watch her. I don’t mind if she has accidents on the floor while I’m gone but I don’t want her developing separation anxiety. I WFH so I haven’t encountered this issue much yet.

Some of y’all are going back to full time jobs after a week where your puppy is left alone for 4 hours at a time. How??

As for her crate training, she does go down for crate naps but she barks and whines for 10-15min before she falls asleep and I keep an eye on her puppy cam the entire time to make sure I take her out before she wakes up and starts freaking out. Hence, I’m not comfortable crating her yet while I’m out of the house.
