His leg chewed in transport with dogs (6)
I believe the answer is:
sleigh
'transport with dogs' is the definition.
(vehicle which may be pulled along by dogs)
'his leg chewed' is the wordplay.
'chewed' is an anagram indicator.
'his'+'leg'='hisleg'
'hisleg' anagrammed gives 'SLEIGH'.
'in' is the link.
(Other definitions for sleigh that I've seen before include "Vehicle suitable for snow" , "vehicle drawn by reindeer" , "13 ac's transport" , "Toboggan" , "Vehicle for transport over snow" .)
