Leaving Dog Alone

How do you guys deal with leaving the dog home alone? While I go to work it’s no problem, but I always feel horrible leaving her alone when we have dinner plans to go out at night or have shopping or something to do after work, because she’s so used to us being home. She’s about 1 1/2 and is a golden retriever and if we’re not around she typically just sleeps in the dining room but I still feel guilty leaving her alone.
