Wild dog's withdrawn, having turned up to eat, initially (6)
I believe the answer is:
coyote
'wild dog's' is the definition.
(I've seen this before)
'withdrawn having turned up to eat initially' is the wordplay.
'withdrawn' becomes 'coy' (I can't justify this - if you can you should believe this answer much more).
'having turned up' says the letters should be written in reverse.
'initially' indicates taking the first letters.
The first letter of 'eat' is 'e'.
'to' back-to-front is 'ot'.
'coy'+'ot'+'e'='COYOTE'
Can you help me to learn more?
(Other definitions for coyote that I've seen before include "American prairie dog" , "Wild prairie dog in America" , "Wolf-like animal" , "-- State, South Dakota" , "Small N. American wolf" .)
