Does this mean Charlie Brown now definitely owns Snoopy? I'm not sure, because he seems to be treating Snoopy as more of a colleague, an equal, than a pet. He says Snoopy has the biggest appetite of "anyone I know."
Check out Charlie Brown's jacket. It's like a suit version of Patty's dress! That pattern of lines, that continues through the fabric of clothing regardless of body contours or perspective, is not uncommon in comics and probably deserves a post off its own. This one isn't it, though.
Also, look at Patty's cross-legged pose while at the phone. It seems like an ungirlish pose, sure, but it's especially weird because Schulz doesn't cheat on the size of her foot there, and so it comes up to the length of her lower leg. It's a pose that's pretty much impossible in real life.
