Chewys urgent life saving surgery

My name is Hailey Vokas, i’m raising money for my dog her name is Chewy. I got Chewy when i was 10, she is now 10. She’s gone through everything with me and has always been a very healthy dog, recently she went into heat, we thought it was just harder on her because she’s getting older but as of 3 days ago she’s made it clear to us she is sick, our vets believe it’s a closed pyometra which is a life threatening bacterial infection on a dogs cervix where the cervix is closed preventing the infectious bacteria from draining out, she has to have a emergency surgery and be put on antibiotics, we’re in a race against time to get this done before it’s too late. Any help is greatly appreciated, this money is strictly for the surgery and the minimum amount they will let us pay to be able to get this done immediately.
