This clue might be a double definition.

'dog' is the first definition.
(Shih-Tzu is an example)

'zeus initially hides in his hut unexpectedly' is the second definition.

(Other definitions for shih-tzu that I've seen before include "Chinese breed of small dog", "Breed of dog with long hair and short legs", "Small Oriental breed of dog", "Dog with short legs and long silky hair", "Short long-haired dog".)

I've seen this clue in The Guardian.
