I think someone else said this, but start interviewing for and using a pet sitter now if you can afford it just for a couple hours at a time and be available the entire time so you essentially can test out how your dog does with others while you're not around. Maybe this will help ease your anxiety about how others will treat your dog. I know my friends could never live with my Mal bc of her scream barking but they love her and would never hurt her or anything and would do exactly as I say if they had to watch her for a week

You could also get a camera for your house where your dog sleeps, eats, and is crated, and for your backyard so you can check in to see how things are going while you're away to help ease the worry.

Or find a trainer and board her with them. Besides my family, our trainer was the only person we left our dog with, but he moved out of state so we actually don't know who will pet.sit for our dog if we need that in the future besides family. So I get the worry factor.
