Certain kennels benefit hot dog! (6,5)
I believe the answer is:
basset hound
'dog' is the definition.
(I know that basset hound is a type of hound)
'certain kennels benefit hot' is the wordplay.
I cannot quite understand how this works, but
'benefit' could be 'asset' (I've seen this in another clue) and 'asset' is found in the answer.
'hot' could be 'h' (common abbreviation eg on taps) and 'h' is found in the answer.
'certain' could be 'bound' (as in the phrase 'it's bound to be') and 'bound' is present in the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for basset hound that I've seen before include "Sturdy hunting dog" , "breed" , "Long-eared hunting dog" , "one that hunts, naturally" .)
