Save Scrappy Doo

Scrappy is my 3 year old pitbull english bulldog mix I adopted a year ago. He has been my best friend, therapist, and adventure buddy for that year. He has been sick the last few days, and has not eaten and has puked several times daily. I took him to the vet and they explained that Scrappy has an internal stomach blockage and needs emergency surgery. After getting an estimate of $8,300, I know there is no way I can afford it alone. Please help, every dollar counts.
