Wait, maybe the user made a mistake in the description. The term "abotonada" could be used incorrectly. Maybe they meant "abierta" (open) or "abrazada" (embraced)? But "abotonada" is past participle of "abotonar," meaning to button. So "buttoned on the backside by a dog"? That doesn't make sense literally. Perhaps they wanted to say that the person is undressing or being taken off by a dog, but the wording is off. Alternatively, maybe it's a mix-up between "abotonada" and another word.
