Meals for sure in crates….. and be ready for some ungodly noises between the two of them... you can never prepare anyone for the noises that come from them until they hear/see it for themselves. 99% of the time it is just noise and I never try and step in, as they need to work it out for themselves. And an adult will "tell" off a puppy all the time.... consider it as training...ggg... keeps those baby teeth off you.
But Lisa is right... all might be really cool until Scarlett figures out this "puppy" is not leaving! Then the real noise starts.... My friend Jeff when he brought Tego home, his other boy, Zadi was thrilled to have a "play toy" until he was tired of him and looked at Jeff with that "OK he can leave now" look. Then he stayed on the bed (Tego was too small to get up there) for days and mostly ignored him until it finally dawned on him, he was not leaving.
