please help my bull terrier gwen.

we had almost paid off jeff's vet bill, using most of tom's pension. which on top of rufus was insane, when gwen our 6 year old bt started peeing blood. took her right into vet. told she had to have kidney removed or she would die. after much fiasco, she has cancer. found a vet who has given us a good prognosis. first vet 6700. about 2500 for second because he is giving us a break. tom has not had full time work since 2010.he loses this job in a week. i live on my ss and disability. the house is for sale, but no takers yet. i see others asking for help and it is amazing to me. they are young, working, haven't been in the breed long. we worked so hard with rufus. now we need help with his granddaughter. should by some miracle, we get extra money, it would go to help other bull terriers. please i know everybody is in need right now, but this run of bad luck we are having is just crazy. thank you!
