Turned up, had a look round, rather puggish (4-5)
I believe the answer is:
snub-nosed
'rather puggish' is the definition.
'turned up had a look round' is the wordplay.
'turned up' becomes 'snub' (snub can mean short and turned up at the end).
'had a look round' becomes 'nosed'.
'snub'+'nosed'='SNUB-NOSED'
(Other definitions for snub-nosed that I've seen before include "Retrousse" , "With a short, upturned hooter" , "With a slightly turned-up hooter" .)
