My Little Puppy Dog

Okay, so here's one more from gym class. Bennett has been great with Beau since we brought him home, but the one thing we have noticed is that he tends to act like a puppy dog some. He had never done that before, so for us it's a new thing (and often entertaining). The kid can stay in character. We play fetch and I'm embarrassed to admit, but he's even tried to eat his dinner like a puppy a few times.....you pick your battles, right? He went into "puppy mode" at gym class for a bit, so I thought I'd let you see what I'm talking about. Please tell me this is normal. :)
