Ariel Winter -- My Dog's My Plus One at Sofia Vergara's Wedding

Ariel Winter is done with men, at least for now, because she's bringing her very cute dog to Sofia Vergara's wedding.

Ariel and the samoyed pooch flew out of LAX Friday for Florida, where Sofia and Joe Manganiello will be tying the knot this weekend.

The "Modern Family" star is currently dating Laurent Gaudette ... but looks like he might've taken a back seat to the dog.
