Bird dog caught, also leashed (8)
I believe the answer is:
cockatoo
'bird' is the definition.
(I know that cockatoo is a type of parrot)
'dog caught also leashed' is the wordplay.
I cannot quite see how this works, but
'caught' could be 'c' (cricket abbreviation) and 'c' is located in the answer.
'also' could be 'too' (synonyms) and 'too' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cockatoo that I've seen before include "Parrot native to Australia and Indonesia" , "White parrot" , "Illegal Aussie look-out man" , "Australian parrot" , "Lightly coloured crested parrot" .)
