Help Us Save Our Pup, Cooper

My fiancé and I rescued our little whipper snapper, when he was 8 weeks, almost 4 years ago. He has been a huge part of our life, and life lessons, our best friend, emotional support, and son. One day recently, he got really sick, so we brought him to the emergency vet. He ended up getting diagnosed with a rare auto-immune disease called IMHA. They still don’t know why. He was in critical condition but we were able to get him stable and back home from the hospital after a week. That, costs us $4k. After he got better, all of a sudden, he got worse again. We just found out he now has diabetes. Both very life-threatening and expensive treatments. We’ve now already had to dish out almost 10k, and will need to continue to give him meds and treatments. I would sell all of my belongings for this little man....We love him too much to let him go. Never would I think I would do this, because I hate asking and my pride is too large, but we are asking for anything...as our bank accounts don’t have much left in it, especially for a mortgage and other things to pay for. Anything anyone can do to help our little man stay alive and back to good health, would be so appreciated and we would be forever grateful. I always pay it forward, so any amount given, I would give back by volunteering and one day by able to give greatly to charities as I always have.
