Plain-English summary
A dog living on a sheep farm in the Cotswolds, UK, experienced a violent sneezing fit and expelled a live larva from a sheep nasal botfly, which is unusual for dogs. The dog had been infected with the larvae for several months, but there were few noticeable symptoms, possibly due to ongoing treatment for another health issue. This case marks the first known instance of a nasal botfly infestation in a dog in the UK. The dog was identified and treated at a veterinary school, highlighting the importance of recognizing unusual parasites.

Abstract
In March 2011, a dog on a sheep farm in the Cotswolds, UK, expelled a mature live third-stage larva of the sheep nasal botfly, Oestrus ovis, after a violent and traumatic sneezing episode. The dog had been infected with first-stage larvae deposited by an adult fly the previous autumn; larval development had progressed throughout the winter and spring with few apparent clinical signs and possibly masked by ongoing immunotherapy for an unrelated condition. Identification of the parasite at the Liverpool School of Veterinary Science was made from a submitted puparium, the "chrysalis" stage to which the larva had progressed within days of its expulsion from dog's nose. To the authors' knowledge this is the first report of nasal botfly infestation of a dog in the UK.
