Awww so sorry bout your pup. That's weird how that happens. My brother had a Golden Retriever and he was bout 10 or so, night before they went on vacation, they let Jake out around 11pm and called him to come in, nothing, they called again, pulled on his runner and felt it was tight but he didn't come. He had died just like that too. I had to put down my 16 yr old mini pin a week before Ron's 2nd surgery last month the 25th. So I know how you feel.
