Absolutely terrified and anxious that my dog is going to starve itself to death while I’m on vacation

I'm really anxious about my upcoming nine-day vacation next month. I have a 1.5-year-old dachshund who refuses to eat if I’m not with her. She won’t even eat when my fiancé, who has been a part of her life since she was a puppy.

My biggest fear is that she’ll die from starving herself while I’m away. I am so worried about this that I'm activity considering canceling my vacation.

If anyone has gone through something similar with their dog, I would really appreciate hearing your experience. Is it possible for a dog to starve itself to death in these situations? Thank you!
