“Skipper” is the dog (8)
I believe the answer is:
springer
'is the dog' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for springer that I've seen before include "Shown [AT CRUFTS]" , "hound" , "Breed of spaniel" , "Type of spaniel" , "Large spaniel with wavy silky coat" .)
