Get the puppy on a good schedule. Up in the morning, out to pee and poo, pick it up, eat breakfast, poo, pick it up. Put him with the bitch for a while. etc. Get his schedule such that you can anticipate poops, and keep the bitch in until he poops and you pick it up. then let her out.
It is natural. She is being a good mother. Much better than the opposite. But yeah, nothing so gross and poopie kisses.
