The Doberman Pinscher was developed in Germany during the late 19th century, primarily as a guard dog. His exact ancestry is unknown, but he's believed to be a mixture of many dog breeds, including the Rottweiler, Black and Tan Terrier, and German Pinscher.
In some cases the symptoms may not be visible and the condition can manifest and become acute. Gastritis affects many people and this condition can get acute as a person ages. If left untreated, erosive gastritis can lead to other health complications. It can also cause bleeding in the stomach leading to ulcers. This can lead to cancer in some patients, especially those who have a thin stomach lining.
Acute gastritis is usually caused by an irritant or infection, and can result in an acute upset stomach, but usually settles quickly with simple treatments when the cause is removed. Chronic gastritis is a condition in which the stomach lining is damaged long-term, often due to infection by H. pylori. Chronic gastritis does not usually cause indigestion or pain, but severe damage may result in anemia due to vitamin B12 deficiency.
