Pet is concerned to get a bit of sausage (6)
I believe the answer is:
caress
'pet' is the definition.
(pet can mean to caress or stroke)
'is concerned to get a bit of sausage' is the wordplay.
'is concerned' becomes 'cares' (to care is show concern or worry).
'to get' means one lot of letters go next to another.
'a bit of' says to take the initial letters.
The first letter of 'sausage' is 's'.
'cares'+'s'='CARESS'
(Other definitions for caress that I've seen before include "Stroke lovingly" , "pet" , "Stroke gently" , "Embrace with affection" , "Gentle stroke" .)
