Do your dogs not make the reasoned choice to poop outside?
Animals make reasoned choices all of the time.
No they don't. Pooping outside is instinct, not reason. Repeat an action enough times (going outside) and they will continue to repeat it. That and the fact that they leave their scent.
Isn't the question about PETS in Heaven. Do we care if scorpions are not admitted.
We want the pets and God loves us so much surely he will give us everything we want which is good.
