Oreo needs surgery, Please help us

Meet our Oreo. She is a Lab/Boarder Collie mix who turned 10 years old this past December. We have had her since she was 7-8 weeks old. She is a big part of our family's lives, going everywhere & doing everything we do. In the beginning of March, Oreo developed MegaEsphogus idiopathically & subsequently was diagnosised with Myasthenia Gravis. Upon Ultrasound, a Thymoma was discovered in her chest. Oreo requires surgery to remove the Thymoma which is close to her heart. Her neurologist feels this is the root cause of her Myasthenia Gravis & possibly her MegaEsophagus. If we remove the Thymoma, she is expected to have a full recovery & hopefully go into remission. Oreo's procedure is scheduled to be done laproscopically, however, the Thymoma is progressing and if this surgery is not done soon, it will need to be done as an open procedure (similair to open heart surgery on a human). This would mean a longer hospital stay & longer recovery time. We have currently exhausted our funding options on the treatments & diagonistic testing that allowed her doctors to arrive at these diagnoses. I'm asking for your help in saving our girl.
