'Swamp People' Star Dead at 13 From Heart Failure

All dogs go to Heaven ... and now one more rambunctious canine has checked into the big puppy bowl in the sky -- Tyler the Swamp dog.

Tyler's owner Janet Mitchell -- "Swamp People" star Bruce Mitchell's wife -- says the dog's heart gave out around 1 am Monday morning after a 3-year battle with congestive heart failure.

Bruce buried the swamp dog in his yard not long after ... alongside other deceased pets.

Hug your loved ones for Tyler and eat a zebra cake.
