March 6, 1953: Who is Snoopy's owner?

This strip finally puts a solid finger on Snoopy's owner. If he's part of Charlie Brown's family, then he must certainly be his dog.

The drawing of Snoopy in the third panel is very appealing, I think.

December 15, 1951: Doghouse Roof

At what point did Patty stop hanging out with Charlie Brown, and go to being more, along with Violet, of a co-antagonist?

My theory is it was about the time that Linus aged to the point of being CB's primary friend. Maybe it was something nagging at Schulz, how the main character of his strip, despite being around six or seven years old, seemed to be spending most of his time with girls. Shermy, for whatever reason, never seemed to relate to him the same way.
