Canine pest (4)

I believe the answer is:

flea

'canine pest' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for flea that I've seen before include "Member of a circus?" , "Small blood-sucking insect" , "Jumping, biting insect" , "high-jumper" , "little pest" .)

I've seen this clue in the Newsday and the Newsday.com.
