Small bed and leash for dog (7)
I believe the answer is:
scottie
'for dog' is the definition.
(Scottie is an example)
'small bed and leash' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'bed' becomes 'cot' (cot is a kind of bed).
'and' is a charade indicator (letters next to each other).
'leash' becomes 'tie'.
's'+'cot'+'tie'='SCOTTIE'
(Other definitions for scottie that I've seen before include "Type of terrier" , "Breed of terrier" , "animal" , "Dog" .)
