Is this trying to say "you visit the dog"? Or "you came to visit, and you came with the dog"?
This is one of those weird sentences which sound incomplete. The verb "a vizita" ("to visit") is a transitive verb, so one would expect an object after it. Something like "Tu vizitezi muzeul cu câinele" ("You visit the museum with the/your dog"), as in you are visiting the museum and you're bringing your dog along. That is, if the dog is well-behaved and the museum accepts dogs in the first place. :-)
Doesn't "cu" mean "with"? I am confused why these comments seem to suggest it is just "the dog"
One comment was a question, the other comment was a troll's work (I think).
As I answered user karalamak, it really is "You visit with the dog", but it sounds weird because you'd normally expect to hear WHAT exactly you are visiting. Something like:
"You visit THIS-OR-THAT-OR-MOUNT-RUSHMORE-OR-SOME-OTHER-PLACE with the dog".
