Please help Mouse with unexpected surgery and vet costs.

Hi, my name is Loriann. It was only a few years ago that I met a beautiful Mastiff who needed my help, or so I thought. For anyone that has rescued a dog, you soon realize that they have rescued you. We named our big girl Mouse because she is little on the inside, but once you have gained her trust, she gives the world to you. Her smile is so big is lights up the room. My family loves her dearly. We knew having a Mastiff would be costly and have until now been covering the financial cost. However, we are unable to come up with the funds needed for surgery, biopsy and X-rays. We spent $900.00 in the last 2 weeks on vet bills already and now need another $2200 to 3500 more. Our sweet Mouse has so much more love to give and a good prognosis if we can proceed with the treatment plan. I am begging , if you can help with costs, please help to give our little Mouse more years of goofiness and joy.
