Party with Mitt Romney, initially a fan of canines (3,5)

'a fan of canines' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'party with mitt romney initially' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'with' means one lot of letters go next to another.
'mitt' becomes 'glove' (synonyms).
'initially' says to take the initial letters.
The first letter of 'romney' is 'r'.
'do'+'glove'+'r'='DOG LOVER'

Can you help me to learn more?
