Civilized dog

The large characters say:

wénmíng yǎng gǒu

文明养狗

"raise [your] dog [in a] civilized [manner]

This one is difficult for the machine translators to deal with.

The fine print says:

qǐng jíshí qīnglǐ chǒngwù páixiè wù

请及时清理宠物排泄物

"Please clean up your pet's excrement promptly"

The machine translators do a credible job with this one.

We've had countless variations on "civilization" + "urination / defecation" in the China department of Language Log.  See "Selected readings" for a bare sample.

Selected readings

• "Be civilized when you urinate" (7/22/23) — with extensive bibliography (see especially the last comment of the last item, which never ends), the famous "Toilet Revolution!!" (11/26/17) — Xi Jinping's pet project
• "Please micturate in the urinal" (4/19/15)
• "No shitting here" (10/10/15)
• "Scoop the poop" (4/15/15)
• "Mandarin morphosyllabic annotation of a Taiwanese sign" (5/13/19)

Of the numberless relevant posts, these are just a few of my favorites.
