I'm unaware of everyone having one. I'll have to disagree on that. My dog is kinda lazy. When I'm not paying attention to him, he'll sleep or sometimes play by himself. However, when I pay attention to him, he's always ready to play...and he never wants to quit once I start. He's 6 years old and will probably start slowing down eventually. But for now, he can be lazy at times...but I wouldnt consider him too lazy.
