Bubba’s Tail Amputation

Hi there, 
My fiancé and I just found out that our 5 year old pittie, Bubba, has a mast cell tumor (cancer) in his tail. It has not spread anywhere else yet, so he needs to have the majority of his tail removed next week. 
We are both young, struggling adults who have not been financially strong. We were not wanting to make a go fund me at all, but do not have much other choices. Thank you so much. Bubba is our entire life, our heart dog. We would be lost without him.
