'barker' is the definition.
(I've seen this before)

'publicised drink with little hesitation in german city' is the wordplay.
'publicised' becomes 'aired' (airing is a kind of publicising).
'drink with' becomes 'ale' (type of beer. I am not sure about the 'with' bit.).
'little hesitation' becomes 'er' (expression of hesitation).
'in' is an insertion indicator.
'german city' becomes 'trier' (I've seen this in another clue).
'er' going into 'trier' is 'terrier'.
'aired'+'ale'+'terrier'='AIREDALE TERRIER'
