Somehow Reg hampered NHS dog (6,8)
I believe the answer is:
german shepherd
'dog' is the definition.
(German shepherd is an example)
'somehow reg hampered nhs' is the wordplay.
'somehow' indicates an anagram.
'reg'+'hampered'+'nhs'='reghamperednhs'
'reghamperednhs' with letters rearranged gives 'GERMAN SHEPHERD'.
(Other definitions for german shepherd that I've seen before include "one wearing dog collar?" , "Alsatian" .)
