At the new place there are people who mow the lawn and maintain lake that sometimes walk past our patio in our back yard. This is new for Kody, and right now he gets very upset by it. I think a positive response to that will be pretty easy to train. But he just did the funniest thing. He has a bully stick and someone walked by, and he was growling at the same time as chewing. The noise was something like, "grrrrawwwaaawwwaaawwaaawaaawaa" as he chewed. It made me laugh.
