Dog knocked over front of hen house? (5)
I believe the answer is:
pooch
'dog' is the definition.
(I know that pooch is a type of dog)
'knocked over front of hen house?' is the wordplay.
'knocked over' says the letters should be written in reverse.
'front of' becomes 'h' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hen house?' becomes 'coop' (I've seen this in another clue).
'h'+'coop'='hcoop'
'hcoop' back-to-front is 'POOCH'.
Can you help me to learn more?
(Other definitions for pooch that I've seen before include "one of our best friends" , "Dog (colloq.)" , "Doggy" .)
