Please help Buddy!!

My dog buddy was viciously attacked by my neighbors 2 pitbulls, they shredded his neck, also they nearly tore off my mothers thumb. Buddy is in critical condition, and we need $3500 to pay for his surgery. We live in poverty, barley able to live week by week, let alone month by month. My mother is a single mom raising 2 teens, her job is an esthetician, mostly dealing with laser hair removal, her job is very hands on, and by the state of her finger at the moment, there doesn't seem to be a chance she can work for a little while. My sister is the only one in my family that can work, she works as a receptionist. I can't work due to my anxiety disorder, which causes me to have panic attacks regularly, as well as my eating disorder, that has caused me many other health issues, such as fainting when I stand for more than 2 minutes. My mothers incredibly wonderful priest put down a deposit so they could perform the surgery. We need $3500 to pay the Vet. Words cannot describe how much buddy means to me, he is everything to me. Buddy has helped me through so much with my depression, he is just the most lovable, kind, loyal, thing I have ever met. I never thought that I could be happy or get any better from my depression, and then buddy came in to my life, and he made me so happy every single day. I am begging, in tears, please, please, any amount can help, please help me save my little baby, buddy
