Gymnastic animal (5)

I believe the answer is:

horse

'gymnastic animal' is the definition.
(I know that horse is a type of Equidae)

This is the entire clue.

(Other definitions for horse that I've seen before include "drug?" , "Equipment in gym" , "Arab" , "what has croup in the end?" , "eg Shire" .)

I've seen this clue in The Globe and Mail.
