- Type Disease
In this condition, there is a narrowing (stenosis) of the pylorus, the region of the stomach through which food and liquid pass into the small intestine. Affected animals vomit after eating. In the congenital form, pups are born with the condition.
- How Transferred
- What to Look for
In the congenital form, the condition usually becomes apparent at the time of weaning. The main sign is vomiting which begins with the introduction of solid food to the puppies.
Diagnosis is based on clinical signs and contrast radiography (showing that the stomach does not empty normally), or endoscopic examination.
Very mild cases can be treated by feeding small, frequent, highly digestible meals. Other cases require surgery; most dogs do well post-operatively.
- Breeding Considerations
Although the mode of inheritance is not known, it is preferable not to breed affected dogs, or their parents or siblings.
