The vomitus often contains old, partially digested blood. Anemia and weight loss are frequently found. Tumors in the pyloric canal region often cause gastric outflow obstruction.
Adenocarcinoma is the most common malignant tumor of the stomach, Benign tumors such as leiomyomas and polyps also occur.
The diagnosis is made by gastroscopy and biopsy of the tumor.
Surgical treatment involves removing the part of the stomach containing the tumor. The prognosis for dogs with benign tumors is excellent. Malignant tumors are difficult to cure.
