A cat and a dog LR confused with second clue (7)
I believe the answer is:
ragdoll
'a cat' is the definition.
(I know that Ragdoll is a type of cat)
'a dog lr confused with second clue' is the wordplay.
'confused with' is an anagram indicator.
'second clue' becomes 'l' (2nd letter of 'clue').
'a'+'dog'+'lr'='adoglr'
'adoglr' anagrammed with 'l' makes 'RAGDOLL'.
'and' acts as a link.
(Other definitions for ragdoll that I've seen before include "cat" , "Toy made with scraps of cloth etc" .)
