Help Save NaKoda

I am NaKoda's owner of 12 years. NaKoda has been my constant companion. Her mate passed from cancer apx 6 yrs ago. Recently, Koda has been diagnosed with cancer and arthritis. Koda has never spent a day/night away from me. She has traveled all over the US in 12 yrs, has been an excellent breed ambassador for the Rottweiler breed, has her good canine citizenship, obedience, and service animal training.  It has come time that she needs me as much as I need her. Being on a single income with no family support of any kind my funds for her treatments/needs are limited. I would normally not do this but I want to save her and without treatments her quality of life will quickly deteriorate and I do not want her to suffer or have to euthanize her if we can avoid it. Helping me to save her life would mean everything in the world to me.
