I have two dogs. They have "Sophia Grace and Rosie" energy. I don't know if you remember these two precocious British girls who were frequent guests on Ellen DeGeneres's program on the USA, and they would talk and rap Nicki Minaj songs. But one of them, Sophia Grace, was super energetic and outgoing and the other one, Rosie, would just hang back and act cute. And that's how my dogs are. They are as close as any sisters despite being unrelated and of different breeds, but one takes the lead and the other is content to follow (or just have a nap in her safe, easily defensible corner).
