Is crazy dog more prettied up? (7)

I believe the answer is:

groomed

I'm a little stuck... Click here to teach me more about this clue!

'prettied up?' is the definition.
I can't judge whether this defines the answer.

'is crazy dog more' is the wordplay.
'is crazy' indicates an anagram.
'dog'+'more'='dogmore'
'dogmore' anagrammed gives 'GROOMED'.

Can you help me to learn more?

(Other definitions for groomed that I've seen before include "Smartened" , "prepared for particular office" , "Neat and smart in appearance" , "Brushed and cleaned" .)

I've seen this clue in the Sydney Morning Herald.
