Arranged some day to get a dog (7)
I believe the answer is:
samoyed
'a dog' is the definition.
(Samoyed is an example)
'arranged some day' is the wordplay.
'arranged' indicates anagramming the letters.
'some'+'day'='someday'
'someday' with letters rearranged gives 'SAMOYED'.
'to get' acts as a link.
(Other definitions for samoyed that I've seen before include "Siberian dog" , "one barking" , "Dog similar to chow" , "Sled dog" , "not setter!" .)
