Sudden death of a young dog

[Natsumi683]

My 17 month old beagle was in excellent health. Two days ago when I came home from work he was very lethargic and had no interest in moving, eating, or drinking.  I took him to the vet.  They expressed his anal glands and did blood work.  His white cell count was elevated but not to any extent to raise alarm.  Yesterday, he showed some signs of improvement in the morning.  As the day went on he took a sudden turn for worse and couldn't drink when water was brought to him.  My husband took him to the vet right away and within an hour he had gone in to cardiac arrest and died.  Unsuccessful attempts were made to revive him.  I was advised no way to know what happened without a necropsy.  I want to know if anyone has any idea why a young and healthy dog would just have a heart attack and die.

I am so sorry about the loss of your pup. It's possible he had a congenital heart problem. Sometimes conditions like this can go undetected, until there is a sudden collapse.
I am very sorry. It's heartbreaking to lose a dog, and so sad when they are young.

Thank you.  I appreciate your comments.  This seems to be a complete mystery as the blood work they did Tuesday evening reflected no indication of poison.   That was a concern of ours as well since he had a habit of getting in to the trash basket.  Other than shredding a diaper or two from a visiting baby, there wasn't anything harmful.
