Me and my dog? (6)
I believe the answer is:
setter
I believe this is a double definition.
'me' is the first definition.
(the person who set this crossword)
'my dog' is the second definition.
(setter is a type of dog)
'and' is the link.
(Other definitions for setter that I've seen before include "Everyman" , "pointer" , "Dog trained to scent game" , "cement, perhaps?" , "Street (anag.)" .)
