Well, my husband and I had that very discussion, He thought my old girl would be upset. What has happened though it that the puppy has embraced her as his mother! And he won't leave her alone nor will he stop lying with her, beside her and on top of her. I swear I can see her rolling her eyes as if to say, "not again!" so it has worked out. The other dogs are pissed off as hell and he doesn't seem to care about them.They are a different breed like of the mutt variety.
