How could it could it be Heaven without dogs? reminds me of the old Twilight Zone where the guy died with his hound. He was invited into what looked like the Pearly Gates but told he would have to leave his dog behind. Of course he told the gate-keeper "no thanks" and moved on. The real gate to Heaven was just a lttle further down the road and the dog was welcomed with the man.
Someplace in the last few months I read a statement that when you go to heaven you will be greeted by every dog you ever owned.
