My baby boys surgery

My best friend and companion has a large tumor on his chest, it was hard to notice because of all his fur but when giving him a big hug I was horrified to find he was not well. it's a large cancerous mass that's attached to his muscle. It hasn't spread or broke yet!  it's quite vascular! and he is quite strong now. But to get a biopsy, lab testing and the actual surgery with the medicine he will need plus the therapy, will cost 6,000. 6,000 I dont have. Im saving as much as I can but I cant do this aloneI have never been a girl that asked for it easy. But I need your help!  I know that beautiful souls all go someday, but I want to give him the best quality of life for all he has done for me. I first got him when he was a baby, so small and scared. He is such a rare kind of animal with the most amazing personality. he is so tender and kind. Anything your willing to contribute will be a goodsend. Please, Will you help me save my dogs life?
