Discovered woman's bred unusual dog (8)
I believe the answer is:
doberman
'dog' is the definition.
(breed of dog)
'discovered woman's bred unusual' is the wordplay.
'discovered' indicates the central letters (dis-covered - outer letters removed).
'unusual' indicates an anagram.
The centre of 'womans' is 'oman'.
'oman'+'bred'='omanbred'
'omanbred' with letters rearranged gives 'DOBERMAN'.
(Other definitions for doberman that I've seen before include "Thematic type [DOG]" , "Originally German breed of watchdog" , "Long-legged terrier" , "Barker" , "...pinscher, large dog" .)
