Dog lead (7)
I believe this is a double definition.
'dog' is the first definition.
(pointer is a kind of dog)
'lead' is the second definition.
(thesaurus)
(Other definitions for pointer that I've seen before include "Dog; cursor" , "Arrow" , "Indicator" , "Gun dog" , "helpful tip!" .)
'dog lead' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for leash that I've seen before include "Line for holding dog" , "Strip for leading, a dog say" , "Line for controlling a dog" , "Strap for holding a dog while walking" , "Restraint for a dog" .)
