Dog ignoring first good hole (5)
I believe the answer is:
eagle
'good hole' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'dog ignoring first' is the wordplay.
'dog' becomes 'beagle' (beagle is a kind of dog).
'ignoring first' means to remove the first letter.
'beagle' with its first letter taken away is 'EAGLE'.
Can you help me to learn more?
(Other definitions for eagle that I've seen before include "Keen-sighted bird of prey" , "ten-dollar coin" , "part of round that's exceptional" , "Valuable piece" , "Hook-billed bird of prey -- old US $10 coin" .)
