Dog lead of dachshund got in Dorset resort (6)
I believe the answer is:
poodle
'dog' is the definition.
(poodle is a kind of dog)
'lead of dachshund got in dorset resort' is the wordplay.
'lead of' indicates taking the first letters (I've seen 'leading' mean this).
'got in' means one lot of letters goes inside another.
'dorset resort' becomes 'poole' (I've seen this before).
The first letter of 'dachshund' is 'd'.
'd' placed inside 'poole' is 'POODLE'.
(Other definitions for poodle that I've seen before include "National dog of France?" , "Curly-haired breed of dog" , "Curly-coated dog" , "Dog (seen in a parlour?)" , "Pet dog with clipped curly coat" .)
