Dog owners, how do you get a depressed doggie to eat?

My in-laws are back home in England for a month and my husband and I are house sitting. Annie has been pretty depressed since Monday, but she hasn't eaten her dinner or even had a sip of water today. She's just laying beside me now sighing 😢 Is there any way I can get her to eat or drink? She knows where her food and water are, but she's not interested. Right now she has a can of wet food on top of her biscuits and walked away from it.
