I'm really still in shock, buy my dog of 12 years just died in my arms about 2.5 hours ago, and I really have no idea what happened. He had no health problems known to us. He was a shepherd/lab/collie type of short hair mix, about 70+ lbs.
He came in from outside as he always does and demanded his treats. He went into another room to eat them, and a minute later we heard him barking in a yelping kind of way. We rushed over, and he was on his side like he was having a seizure. He had made a bowel movement of both types, and his body was convulsing.
He seemed alive for a minute, but not responsive to me or my wife. I don't think he was choking. I tried to do some type of CPR, but I think he was already gone. I kept at it, and I thought he was responding, but now I think it was just muscle spasms.
I suppose the total elapsed time was less than a minute. There was no sign of his dog biscuits around, and I couldn't find anything in his throat, at least as far as I could reach.
His name was K.C. (pronounced as Casey).
Go easy old friend.
