Dog-themed comics with rivalry

Puppy vs. Baby: Hilarious Territory Battle Unfolds in the Latest Dog Eat Doug Comic Strip!

In the first dog eat doug comic panel, baby Doug pushes on puppy Sopie's dog bed.
In the second dog eat doug comic strip panel, puppy Sophie says, "I get it. You want to mark a little territory of your own."
In the last panel of today's Dog eat Doug comic strip, puppy Sophie says, "Before you get carried away, might I remind you how I mark my territory?"

If you’re going to do bathroom humor, make it subtle.
