Don’t get me started on that one... I always wondered if God wanted us to have the afterlife be a true paradise would we not only out previously arriving family and friends, but be with the 4-leggers we had a bond with? My wife being Orthodox Christian, and me from a Protestant background... Our son goes to Saturday Orthodox School, and one of the priests told him exactly that (animals have no souls). This provided an interesting discussion. We told our son to listen to the Father re: Jesus, but quietly disagree on the animals in heaven part..
Plants have the simplest soul for it drives them to grow. Animal souls possess that property plus the ability to act in some degree according to their own inclinations. However, it is the soul of man that has all those properties plus the ability to know God. That's what sets humanity apart.
Does that get Lexington into heaven? I don't know. Someone posted months ago since God wants you to be eternally happy with him in heaven, if having your beloved canine companion with you was intrinsic to that happiness, then God would certainly permit it.
I don’t know the Lord’s will regarding dogs in Heaven, but anything for Him is possible.
It is in the Bible that animals will be in Heaven. They will not be carnivorous, nor poisonous, but they will be there.
And, I kinda think Father, God likes animals...He made so many of them after all.
