Luna's Tumor

Hi! This is Luna she is a pure breed Labrador and she’s barely a year old! On October 23, I was giving Luna a bath and I noticed a huge bump near her ovaries. I had a strong feeling that it wasn’t god that she had it. We immediately took her in to a local vet to get her checked and it turns out she has a tumor, the Vet told us that we would need to have her get surgery as soon as possible. This breaks my heart because Luna is one of my favorite dogs and I would lose it if something ever happens to her! Today October 24, I noticed that the the bump started to grow more so surgery is no option!
Anything will help and I appreciate you for taking the time out of your day to read about Luna, Thank you!
