Dog finally gets bed and leash (7)
I believe the answer is:
scottie
'dog' is the definition.
(Scottie is an example)
'finally gets bed and leash' is the wordplay.
'finally' suggests the final letters.
'bed' becomes 'cot' (cot is a type of bed).
'and' means one lot of letters go next to another.
'leash' becomes 'tie'.
The last letter of 'gets' is 's'.
's'+'cot'+'tie'='SCOTTIE'
(Other definitions for scottie that I've seen before include "Breed of terrier" , "Type of terrier" , "Dog" , "animal" .)
