Suiting a solitary person who went mowing with a dog? (3-3)

I believe the answer is:

one-man

I believe this is a double definition.

'suiting a solitary person' is the first definition.

'who went mowing with a dog?' is the second definition.
(ref to nursery rhyme 'One Man Went to Mow')

(Another definition for one-man that I've seen is " (Of show) performed by a single person".)

I've seen this clue in The Guardian.
