They did really well. He's only 9 weeks old, the first couple of days they were in the same room as the baby, but never actually realized there was a baby here. That was probably really good, because they got very used to her smell before seeing her. This morning he (the dog) finally noticed Aurelia, and got very excited. Lots of play bowing and barking, lol. She's not big enough for that yet though.
It's really nice because he's not a nippy puppy at all, he plays using his feet mostly.
