Phrase I developed for muscular pooch (4-3)
I believe the answer is:
shar-pei
'muscular pooch' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'phrase i developed' is the wordplay.
'developed' indicates anagramming the letters.
'phrase'+'i'='phrasei'
'phrasei' anagrammed gives 'SHAR-PEI'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for shar-pei that I've seen before include "Chinese dog breed" , "Chinese dog; I phrase (anag.)" .)
