Shadow needs help

Let me start out how we got Shadow . I found an add that said free purebreed beagle so i call it. What i was told is she was turned into the pound because she was to scared to train and to hunt and the guy didnt want to shoot her. The lady we got her from took her from the pound and only had her 1 month and had to get rid of her because Shadow was to scared of people and would run off. So we really dont know what the original owner did to her. She was so scared when we got her home we put her in the fenced yard and it took us HRS to get her in the house Im thinking what did we get into. LOL It was over a year befor she slowly came around to us.(ME FIRST) Thats why I cant loose her.She is still jumpy at other people (runs and hides) Any way back to Her.
Shadow started showing signs of feeling sick the other day and was spotting dark blood. She is the one on the left leaning up against the tree.
After taking her to the vet and a few x-rays and blood test she has what they called  ovarian cyst rupture symptoms. She has puss sacks about to rupture ( NOT GOOD) so she needs surgery ASAP That they are going to do it Today before its to late. The problem is if it turns out to be a tumer its to late or if its a puss sack (multiple) sacks showing on the x-ray) and they burst removing them it will kill her. She needs her uterus removed to save her life. donations needed PLEASE i dont have the money and i cant loose my baby.
