My condolences for your loss. We have lost two to DCM so far and one to cancer. Currently have one 10 y/o male that so far has been given a clean bill of health on his heart and one who 13y/o female who had her rear leg removed for osteosarcoma and just completed 4 chemo treatments. She was also diagnosed with a slight heart afib and started meds for that, but the doctors thought it could be related to the cancer and a few have said that since the surgery the afib looks to be gone and was theorized to do so. She goes back in September for another cardio checkup and they gave her a medal and scarf for competition of chemo and being currently in remission of cancer following scans and bloood work. She is doing great at the moment. We do at least annual cardio work ups on ours including ecg and ekg. Won’t stop the disease since it’s genetic, but it gets us in front of it to help maximize quality of life. Unfortunately, as with yours it can still take you by surprise.
Thoughts with you guys today. These guys a better than most people and are sorely missed.
