PET EMERGENCY - Needs Surgery ASAP

My beautiful brindle pit bull Ruthann needs a surgery to cut a Pericardial window in the sac around her heart. She has had to have a needle inserted in the sac around her heart twice now in the last two weeks. The Vets give her a good prognosis of a healthy life after the surgery. I have spent 3k in the last two weeks on treatments and tests to make sure there are not other issues. The surgery and two days in the pet hospital was quoted at 6,406 dollars. Any donation helps. Thank you and God Bless!
