Indiana following his innate instinct to howl along, but still a bit confused as to what is going on
We thought this was pretty adorable and have been howling to get him more used to it every so often for the last few weeks, to the (I'm sure) delight of our neighbors. He only participates when he is particularly excited about something: Dad comes home, it's time to go out, or he feels like chasing the cat. Howling has actually been a great deterrent to his last foible; if he starts chasing the cat, I coo at him, he howls for a bit, and then he seems to settle down. It has been working better than crating him as a time out, although the experiment for this situation is only a few days old.
Indiana howls like a champ now. And, so far, only does it when we do. *knock on wood*
