Doppler has been an absolute sweetheart when it comes to dealing with Virga. He'll get this look on his face like he's saying, "Children..." He gets extra treats most of the time because he's so good tempered with her. Although I don't think Doppler could be mean if he tried. It's great having the two of them. And I like that they're pretty close together in age. They've both got the puppy energy still.
