My beautiful little boy Magnum died on Christmas day at 10:00 at night when we let him out to go the bathroom. After 10 minutes when we called him in we found him dead in our front yard.I hope he didn't suffer. I wish I would have been with him when he died. We think he must have had a heart attack.He was the best dog and such a loyal and great companion to me. He is sadly missed by us.
