Canine tip (7)
I believe the answer is:
pointer
I believe this is a double definition.
'canine' is the first definition.
(pointer is a kind of dog)
'tip' is the second definition.
(I've seen this in another clue)
(Other definitions for pointer that I've seen before include "stick used for instruction?" , "Dog; cursor" , "Tip; dog" , "Hint (for a dog?)" , "Suggestion" .)
