A female coworker in her mid-20s asked me, a 30-year-old man, what type of dog I thought would best represent her and some other coworkers. She then said I gave off "St. Bernard vibes" but didn’t explain further. What does that even mean? Should I interpret it as a compliment?

A colleague of mine, who is not single, posed a question to me and described me in a certain way before laughing and refusing to explain what it meant. I’m posting here because every other "ask women" community I've tried has rejected my submission. After reaching out to the moderators, they encouraged me to go ahead and share my post.
