==Diagnosis==

Diagnosis of gastric motility disorders is usually made once other causes of vomiting have been ruled out. The normal gastric emptying time of a dog is 10-12 hours. Therefore, a dog that vomits an undigested meal more than twelve hours after feeding should be strongly suspected of having a gastric motility disorder if an outflow obstruction and inflammatory disease have been excluded.

Contrast radiography may support a diagnosis of a gastric motility disorder:

*Retention of a barium meal for more than 10 hours

*Half of the animal's daily caloric requirement should be fed as canned food mixed with 5% by weight of barium sulphate. Radiographs are taken every hour until the stomach is empty. This amount of food is normally emptied by the stomach in 5-8 hours. If food is still present after this time, a motility problem is suggested.
