  1. Nigel Harcourt‐Brown

    Nigel Harcourt‐Brown qualified from Liverpool in 1973. He runs a busy four‐person first‐opinion and referral practice in Harrogate, in partnership with his wife, seeing dogs, cats, rabbits and birds. He was awarded an FRCVS in 1995 for his thesis entitled ‘Diseases of the pelvic limb of birds of prey’, and is a past recipient of the Melton award and William Hunting award. His main interests are surgery and endoscopy.


RHINOSCOPY is a useful technique in the investigation of dogs with chronic unilateral or bilateral discharge. It allows the clinician to examine the nasal cavity directly and obtain diagnostic samples of tissue in a selective manner, and it can also be used to assess the progress of treatment. An article in the last issue reviewed the anatomy of the dog's nose, described how to perform rhinoscopy and illustrated the normal endoscopic appearance of the nasal passages (In Practice, April 2006, pp 170–175). This article discusses a number of conditions commonly associated with nasal discharge in dogs. Some of the typical endoscopic features of each are illustrated to assist the practitioner in the diagnosis of these, often challenging, cases.
