Help Us Save Eva

Eva, the beautiful lab-mix above is a cherished family member and has, over the past eight months, developed a tumor on her back ( near her right hind leg ). It has slowed her down, drains her of energy And causes pain when touched. She has been apart of our family for more than 6 years and has grown up with our son, of whom loves her with all his heart and is constantly worried about.  We have gotten estimates to have the tumor removed, and range from 5k-6.2k depending on it being a solid mass or not. We have already put the surgery off for too long due to hard times And do not wish to see her in this state any longer. Any help would be appreciated!  We just want our happy, hyper girl back!
