The present report describes a case of pyloric wall leiomyoma in a shelter dog with a history of vomiting, pica, licking and chewing the walls of the kennel. The clinical, radiological, ultrasound, hematological and blood chemistry examinations showed no abnormalities. A compulsive oral disorder was diagnosed and treatment with behaviour therapy instigated. The compulsive oral behaviours stopped following behaviour therapy, however, the vomiting persisted, suggesting the need to proceed with further diagnostic exams. The ultrasound examination, repeated after 6 months, had revealed the presence of a hypoechoic mass (3.52 cm) in the pyloric-antrum obstructing the gastric outflow. Following gastric dilatation the mass was surgically excised. Histological examination revealed a pyloric leiomyoma. In clinical practice this case highlights the importance of gastrointestinal diseases in the development of behaviour changes related to pica.
