Guide to Dog Gastritis
"Dog gastritis is a general term used to
describe a condition where the lining of the
stomach becomes irritated and inflamed. The most common cause is a food
from eating something your dog shouldn't such as grass. The irritant,
such as the grass or infection inflames the lining of the stomach
(gastric mucosa), causing the release of of mediators that cause the
secretion of acids and a change in the way the stomach functions. This
alerts the center of the brain that stimulates the vomiting reflex.
There are two
types of gastritis, acute gastritis (comes on suddenly) and chronic
gastritis (vomiting that lasts more than 7 days).
In most cases, the patient will recover in 1 to 3 days after
treatment as outlined below. If veterinary care is needed, the
Vet will provide anti-vomiting medications, and medications to protect
the gastrointestinal system. If ulcers are present (lesions or
wounds on the stomach wall) they are treated with H2 receptor
antagonists. The patient prognosis is based on the cause of the
