Ha, you're right, Dex would be a pretty useless stat.

How about combining them into four stats?

Physical- anything relating to completing a task of labor.
Mental- anything requiring book-smarts, like accounting and so on.
Emotional- Anything requiring people skill, like administration, being a receptionist, etc.
Maternal- A catch-all for all the cow-ish activities like expressing milk, giving birth, raising new cowgirls, etc.

That will probably be less of a monster stat-wise to keep track of, you think?
