I think if it was my dog, that I would be a wreck worrying about it the whole time I was gone.

So I would be thrilled if you offered to come and let my dog in and out of the house and I would take you up on it.

I have this arrangement with my neighbor. I feed her dogs in the morning and then let them out in the yard for the day.........checking on them from time to time. Then I let them in the house in the evening and give them their treats.
