There is an episode of the "Twilight Zone" where an old man and his dog were out by the river hunting coon. Well, the dog got a scent, and off he goes. He chases the coon out on an old tree that has fallen into the river. The coon jumps in, and the dog follows. The old hunter gets to worrying that the coon might drown his dog, so he jumps in , too.
The next thing you know the old man is coming to, on the bank, and there sits his dog, who he figured dragged him out. But he can't find his gun, so he starts looking, and sees something terrifying. It is his body and the dog dead. They both were drown.[there's more minutiae I can't remember]
He and his old dog are walking down the road, and he sees a road off to the side with a man standing there. And he asks the man, is this heaven. The man replies, welcome brother. The old man and his dog start to go in when the man , says, he can't enter here, and walks toward the dog which starts growling.
The old man says, well if a dog is not welcome here it sure is no place I want to go. And they walk off.
On down the road a little ways they come to another
road with a man standing there. The old man said I talked to that feller back there, and he said I could come in, but not my dog. The man says, they don't allow dogs or any animals to enter that place, only man.
The old man asks , well what about here, and the angel says, of course he can. Welcome home brother,
and pets the dog as he and the old man enter.
Maybe some things are forever.
