A very sad day

Yesterday we went to the Romgi's parent's house to do laundry. A lot of laundry. So much that we ended up staying overnight, and when we got back this afternoon...

Puppy was dead.

I am very sad. We only had him for 4 or 5 months. It was 63°F when we came home; could it have gotten really cold overnight? Or maybe he had some food allergy we didn't know about? Or maybe...he was lonely?

I don't know. But I miss hearing him sneeze.
