Finlos Surgery

Hello ! My name is Sandra and Finlo is my pup ! I’ve had him for quite a while now, he was a rescue from the Carter county pound. Unfortunately he wasn’t fixed when I got him and was unaware, and the idea of doing that at the time to a recently abused dog wasn’t something I wanted to put him through ! 
Unfortunately, he has grown a tumor in this area and needs it surgically removed and neutered. This medical service will cost me roughly around 800, and as someone who has just recently graduated and started working in my career field, I don’t quite have that much money to put directly towards my pup. 
Anything would help !! As he is healthy in all other areas and still young for his breed. This surgery is necessary for his comfort, and his health risks in the future ! 
Thank you !!
