Pomeranian dog quaffing river spray (6)

I believe the answer is:

spritz

'spray' is the definition.
(thesaurus)

'pomeranian dog quaffing river' is the wordplay.
'pomeranian dog' becomes 'spitz' (I've seen this before).
'quaffing' indicates putting letters inside (to quaff is to drink or consume).
'river' becomes 'r' (abbreviation for river).
'spitz' going around 'r' is 'SPRITZ'.

(Another definition for spritz that I've seen is " Delivery from a Mister".)

I've seen this clue in The Times.
