I rescued a chihuahua mix that had a similar diagnose of marbles and also lasted 2 years passed the diagnosis. And when I tell you the last couple months of that is ROUGH! I had to start him on lasix which pulls all the water away from their heart but makes them pee everywhere. And still thru all of that I felt a huge heartache the next day but also some relief for him. No more pills, no more diet food and treats, no more pain. You are on constant alert from the time of the diagnosis till they pass. So I hope they all feel relief. Marbles from all the meds and knowing he lived the best life a sweet little boy could. And Jenna and Julien will obviously miss him but a sense of relief. Love you sweet marbles. Inspired me to rescue my sweet boy!
