Advice needed from dog people

Is she just communing with her little dog over a faux pas involving serving the wrong cute item to human guests? Or does she ordinarily give Baby Bear (this dog) lemonade to drink (and this time it was pink, which disturbed him)? Or gives him ice cubes to cool off (I do that for cats in very hot weather) but normally plain water ice and this time pink lemonade ice cubes?

Is lemonade even safe for pets? And do they like it at all?

Mnemonic

Hovertext: “It’s definitely not the time to try drinking beer before liquor.”

Clearly there’s some sort of reference to “leaves of three; let it be” for poison ivy, but it’s still a CIDU for me.

I suggest that it’s more fun if we avoid peeking at explainxkcd until the discussion here has run its course.
