Beast retiring with a broken toe (6)
I believe the answer is:
coyote
'beast' is the definition.
(I've seen this before)
'retiring with a broken toe' is the wordplay.
'retiring' becomes 'coy' (both can mean shy).
'with' says to put letters next to each other.
'a broken' indicates an anagram.
'toe' with letters rearranged gives 'ote'.
'coy'+'ote'='COYOTE'
(Other definitions for coyote that I've seen before include "American prairie dog" , "North American wild dog" , "-- State, South Dakota" , "Small N. American wolf" , "Small wild dog" .)
