Pet's info: Dog | Chihuahua | Female | spayed | 12 years and 7 months old | 4.8 lbs
My 12.5 year old Chihuahua died suddenly of heart failure. I was wondering if the sedated teeth cleaning she had 6 months ago might have had something to do with it. Her blood work 6 months ago was normal. She had no symptoms of being sick, she ate that morning but passed 12 hours later.

I am very sorry your Missy passed. It is safe to say the the teeth cleaning under anesthesia 6 months ago was not the cause for this, especially since her pre-surgical exam and blood work did not show any abnormalities. Seeing that she was fairly old, there is a possibility she developed a heart condition in the past few months, or she also may have had a sudden blood clot that was fatal. The only way to find out would be to send her to a pathology lab for a post mortem. Again, I am very sorry you lost your baby. At least she did not suffer with a long painful condition.
