Dog Died SuddenlyMy dog was a perfect, very fit 7 year old Amstaff. We woke up this morning, and nothing was wrong. I gave him his breakfast, he ate it with a healthy appetite as normal. 10 minutes later he was dead. I just saw him lying on the floor, with urine next to him. He was not sick, very active and happy 10 minutes before we found him lying there. The vet said it was a heart attack.
