Man and dog following saint (7)
I believe the answer is:
bernard
'saint' is the definition.
(I've seen this before)
'man and dog following' is the wordplay.
'man' becomes 'Ber'.
'and' says to put letters next to each other.
'dog following' becomes 'nard' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ber'+'nard'='BERNARD'
Can you help me to learn more?
(Other definitions for bernard that I've seen before include "Sainted dog for the mountains" , "Saint - - , dog" , "St - - , dog" , "Saintly dog and department store brand" .)
