Dog day some managed coolly (7)

I believe the answer is:

samoyed

I'm a little stuck... Click here to teach me more about this clue!

'dog' is the definition.
(Samoyed is an example)

'day some managed coolly' is the wordplay.
'day some' anagrams to 'SAMOYED'.
However, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for samoyed that I've seen before include "Dog - someday (anag)" , "Some day (anag) - dog (from Siberia?)" , "Arctic dog" , "Dog similar to chow" , "Breed of white dog from Siberia - May's ode (anag)" .)

I've seen this clue in The Hindu.
