Yea it’s odd, the dogwas in a crate I read so perished from lack of food and water. Maybe his wife also had a heart attack from the shock of him dying . I take the same med, Diltiazem for an irregular hear beat but also helps blood pressure.
She was 65 so possible the shock and panic affected her heart.probably getting it for him hoping it would help
My wife had an aunt pass and the next day her husband died.
Will know eventually
