Condition making a horse trot strangely (4,6)

I believe the answer is:

sore throat

'condition' is the definition.
(sore throat is a kind of condition)

'a horse trot strangely' is the wordplay.
'strangely' indicates an anagram.
'a'+'horse'+'trot'='ahorsetrot'
'ahorsetrot' is an anagram of 'SORE THROAT'.

'making' acts as a link.

(Another definition for sore throat that I've seen is " Inflammation affecting speech".)

I've seen this clue in The Telegraph.
