Some of the stuff Jack has to deal with

Living under the same roof as The Dafe isn't always easy. He isn't really aware of the concept of personal space, he assumes all of the food in the house is for him, and he sees every space in the house as a potential napping location for himself. Generally speaking, Dave just tends to be a major goofball. Below, you can see one such instance of Dave being a goofball. No one has any idea what this was meant to accomplish, most of all Jack. Perhaps he was just trying to warm up Jack's tail for him, but it's more likely the even Dave doesn't know what he was doing.
