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.

Underlying causes of vomiting should be addressed first.
Underlying causes of vomiting should be addressed first.
Drugs that promote gastric peristalsis/motility may be administered once a diagnosis of a gastric motility disorder has been reached. Several drugs have been proposed and may include:
*Cisapride (30 minutes before each meal)
**reduces tachygastria
**increases tone and amplitude of gastric contractions
**relaxes the pyloric canal
**increases contraction in the proximal small intestine
*[[Macrolides and Lincosamides|Erythromycin]]
**acts on smooth muscle motilin receptors to increase gastric contractility
*Metoclopramide
**increases gastric peristalsis

==Prognosis==
Animals that respond well to medical management have a good prognosis. Those who respond poorly to medical treatment have a poor prognosis.
