Hello - I am sorry you are going through this
My boyfriend and I are gone from about 8am-6pm every weekday. We have a dog walker who comes 3 days a week and then we each take a turn and go home one day a week. It is hard and gets costly but it is so worth it to me and for Lula and for my own peace of mind!
We keep Lula in a play pen with her bed, tons of toys, food and water always and we leave the TV sound on for her throughout the day. We also give her the Kong right before we leave each time. She is just over 6 months old now and I am hoping to give her free reign of the living kitchen area in 2-3 months once she is fully trained and maybe when the biting calms a bit!
It is hard at 1st without a doubt but it is doable!! Good luck!
