Hoss's Procedure Costs for Tumour

Hi there, my name is Shana and I'm raising funds for my dog Hoss. A large tumour was recently found on one of his kidneys and the vet bills have been piling up. The vet's current estimate for his ultrasound guided biopsy, including all of the supplementary fees for general anesthesia, blood panel, etc. is $2600 and I am just not able to afford that by myself right now with working only part-time and full-time school. Any help would be immensely appreciated from the bottom of mine and Hoss's heart. All I want is to get Hoss happy and healthy.
