I Found My 8 Year Old English Bulldog Dead This AM He Had No Prior Symptoms....he Had Slobbed, Pee'd And Has A Little Poop Coming Out, Could It Have Been Heart Failure?
A common death in dogs believe it or not is toad toxin.
I am so sorry for your loss, and I understand wanting to understand what happened.
Poop and pee coming out of a dog that has died is normal whatever the cause. The muscles that control bowels and bladders relax with the death and their contents flow out.
As someone else mentioned a blue tongue or even a gray tongue or gums would be indicative of a heart attack. Slobbering could be a sign of a stroke or poisoning.
Back to the heart issues. I have boxers which are notorious for heart issues, as are Bulldogs. I lost my first one to a heart attack. She had no symptoms. While my second did not succumb to his heart issues he had them all the same. We found out by pure accident when he was on an EKG before surgery. He never had the surgery and was at a cardiologist the next day. He was on heart meds for the last 4 years of his life, which kept his arrhythmia under control.
I took my current boxer in to see a cardiologist at the age if six to have a full work up to see if there were any issues and to catch them early if so. Nothing showed up. She is now 8 and has had a second work up after a collapse earlier this year, and still seems to be doing fine. She will have to have an annual screening though as we have no real answer for her collapse, which could have been caused by an odd arrhythmia.
Often times the first sign of a heart condition, is sadly the last as it is very often fatal. Again I am so sorry for your loss.
