Dog shows arranged some day (7)
I believe the answer is:
samoyed
'dog' is the definition.
(Samoyed is an example)
'arranged some day' is the wordplay.
'arranged' is an anagram indicator (letters rearranged).
'some'+'day'='someday'
'someday' is an anagram of 'SAMOYED'.
'shows' acts as a link.
(Other definitions for samoyed that I've seen before include "Dog - someday (anag)" , "one barking" , "not setter!" , "[HOUND] ?" , "Breed of white dog from Siberia - May's ode (anag)" .)
