Off course, land without a dog (9)
I believe the answer is:
scoundrel
'dog' is the definition.
(both can mean a dishonourable person)
'off course land without a' is the wordplay.
'off' indicates anagramming the letters.
'without' is a deletion indicator.
'course'+'land'='courseland'
'courseland' with 'a' removed is 'courselnd'.
'courselnd' is an anagram of 'SCOUNDREL'.
(Other definitions for scoundrel that I've seen before include "Rat" , "Villain" , "Person that's low" , "Red consul may be a rogue" , "Disreputable type" .)
