Dog drinks and pants (5,6)
I believe the answer is:
boxer shorts
'pants' is the definition.
(I've seen this before)
'dog drinks' is the wordplay.
'dog' becomes 'boxer' (boxer is a kind of dog).
'drinks' becomes 'shorts' (short can mean a drink of spirits).
'boxer'+'shorts'='BOXER SHORTS'
'and' acts as a link.
(Other definitions for boxer shorts that I've seen before include "Male underwear" , "pants" , "Men's underpants" , "Men's underwear" .)
