Dogs injured assailant (9)

I believe the answer is:

alsatians

'dogs' is the definition.
(alsatian is a kind of dog)

'injured assailant' is the wordplay.
'injured' indicates anagramming the letters.
'assailant' with letters rearranged gives 'ALSATIANS'.

(Another definition for alsatians that I've seen is " AA instals strange dogs".)

I've seen this clue in The Telegraph.
