In this research 32 dogs were studied for oesophageal spirocercosis. Microscopic and macroscopic examinations revealed that 8 dogs (25%) were infected with spirocercosis. Oesophageal granulomas in infected animals vary from 3mm to 4cm in size and a total of 28 S. lupi granulomas were recorded in infected dogs. Most of these granulomas were found in distal part of oesophagus. There were no signs of neoplastic changes and aortic aneurism among infected dogs. Microscopic examinations of central part of parasitic granuloma showed presence of parts of nematodes surrounded by neutrophils. The results of study showed that prevalence was significantly more in male dogs than the female dogs (P<0.05). However, the incidence had no significant variation with age and season (P>0.05).
