Call dog another animal entirely (8)

I believe the answer is:

ringtail

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

'another animal entirely' is the definition.
I can't tell whether this definition defines the answer.

'call dog' is the wordplay.
'call' becomes 'ring' (telephone call).
'dog' becomes 'tail' (synonyms).
'ring'+'tail'='RINGTAIL'

Can you help me to learn more?

(Other definitions for ringtail that I've seen before include "Sort of cat" , "Type of cat" , "Sleepwalker" , "Possum" , "creature" .)

I've seen this clue in The Times.
