The other day when the UPS man came to deliver a package, Spike didn't greet him at the door. Spike didn't even bark. It's cold here in Minnesota. Spike took the path of least resistance. He remained in his pod. The delivery man said that he didn't hear "the dog" barking. That was because Spike was in his pod. It took me a little while to find my "watch dog." I finally did. Spike stayed in his nice, warm pod.
