Needle for example for canine? (7)
I believe the answer is:
pointer
I believe this is a double definition.
'needle for example' is the first definition.
(something with a sharp point)
'canine?' is the second definition.
(pointer is a kind of dog)
'for' acts as a link.
(Other definitions for pointer that I've seen before include "Arrow" , "Guide" , "Smooth-haired game-dog" , "Dog < or horse or" , "Signpost - dog" .)
