Vet Costs for Freya the Irish Wolfhound

This is my pup Freya. I have raised her for 11 years and she is my best friend! That said, she's had some medical issues lately. She was diagnosed today with closed Pyometra, which needs immediate surgery, or she could pass from septic shock within a short period of time. Luckily, with the help of friends and family, I was able to secure the surgery. That said, the surgery is a whopping $7000 to $8000 + dollars (estimated). It requires two overnight stays and as you can see on the statements I've provided, it is quite insane. I had to give them literally $3500 up front. How is anyone truly expected to cover such a cost? This is why I need some help. I make 20 dollars an hour. I work full time, but it is not enough to cover these massive costs. I would appreciate your help with this. If you cannot, that's okay too. I hate asking for help, but I could not bring myself to put down a healthy, happy dog that just has medical condition that COULD be fixed. The doctor says she has outstanding health outside of this one issue. Thank you for considering
