There wasn't a whole lot of pug socializing, at first. Sashacleo kept to themselves, avoiding the over-friendly puppy.
Bunni's persistence wore off. First, she won over Sasha (or beat her resistance down -- Sasha is in the foreground, snuggling Bunni's bum).
Then, Bunni managed not only to get Cleo to tolerate her proximity...
...but also her cuddlage.
Look at these pugs. You can't separate them.
