How does everyone feel about leaving their puppy at home while working 8 hr shifts.

I just got a puppy couple of months back. He is currently 16 weeks old. This week his regular daycare caregiver is undergoing a surgery and will not be available for next couple weeks. I thought of using this time to train him to be home for 8 hrs.

Previously, he was left alone for short periods of times – for groceries, half day work schedules, quick drop off or appointments, but never full 8 hrs. I feel guilty seeing him through the Ring camera running near the door and sitting for few mins (guessing he is hearing noises out of apartment and thinks I am home 🥺) or Howl when he hears my voice over the camera (husky) 😭

Will i get over this? Is it okay to leave a 4 month old Husky all alone for 8 hrs? How can I do better so he doesn’t feel separated.

Future plan is to switch between daycare days and home until he is a year old.
