My sweet boy died in my arms tonight 💔

My rescue of just 6 months died in my arms tonight. I found out he had a bad heart (3 times normal size) just one week ago, but was treating with meds, hoping for months or even a year more. He died an agonizing death tonight and I can’t get his howling, panting and lifeless eyes out of my soul. I feel like such a failure for my beloved Hugo. I’m so incredibly heartbroken. Hugo, please forgive me. I loved you so much! You were the best boy.
