Firefighters were called on to free a horse after the panicked animal had got itself stuck inside a trailer.
The service's technical rescue unit attended the incident, on the road between Wistow and Kibworth Harcourt, at just after 11am today.
Crews used cutting gear to free the distressed animal.
A spokesman for the fire service said: "We don't know quite how it happened but the horse somehow got itself stuck, half in and half out, through the observation window.
"It was panicking and a vet had to be called out to oversea the rescue."
He added: "The team removed the side of the horsebox to free the horse, which was then checked over by the vet.
"A representative from the RSPCA was also in attendance but, fortunately, the animal was unhurt.
"We left the incident as it was being transferred to another horsebox to resume its journey."
A mile-long stretch of road was closed by police while the incident was dealt with.
It was reopened by 1.30pm.
