I’m so sorry for what happened to your boy. We are still torturing ourselves, wondering if we missed something. But the signs were difficult to put together. He was behaving normally up until the moment of his collapse.I've lost a couple dogs to this disease. The last one was a little over two years ago. He was six years old, and boarded along with our other two dogs, at a place we have gone to for many years, and still use. We had just boarded a cruise, got a frantic message he had collapsed, and was at the ER vet but was stable.
Two hours he went into cardiac arrest and died. I still feel guilty that he died with strangers. And still wonder if I missed something. But thinking back, there really was no clues, he was fine in the morning and gone by midnight.
It is an absolutely awful disease.
