Help Pay for Rex's veterinary fees

Rex is probably one of the happiest most loving animals you'll ever meet. He brings so many people so much joy and has become a guardian over my fiancé's 11 yr old daughter. Recently Rex became very ill, unable to eat, very weak and lethargic, with diarrhea, vomiting and bleeding. We rushed him to an emergency vet in our area and were informed he has a massively swollen prostate causing him an extreme amount of pain and if not treated could cause his further decline. He is such a huge factor in our lives and if we are unable to pay for treatment it will devastate us. Please help in any way you can, we don't want to lose our boy!!
