This can be diagnosed when dogs seen eating something that irritates, acute gastritis usually inferred from the history and physical examination are met. Abdominal radiography and clinical data indicate pathology if animals are sick or if there is suspicion of other diseases. If vomiting still lasts 1-2 days after being given fluids and symptomatic therapy, the diagnosis of the above might be true. Acute gastritis shows symptoms that vary in accordance with its cause (e.g. foreign bodies, intoxication). History and physical examination are both necessary. Pet owners should keep an eye on and if the conditions are worsening or no improvement in 1-3 days should do blood tests, urinalysis and serum biochemical.

The principle of treatment is making dogs not to eat and drink for 24 hours to control the vomiting. If vomiting continues, or if the animal becomes depressed because of anti-vomiting, they can be given parenterally. When feeding begins amounts of water can be given frequently in small amounts. If animals drink without vomiting, some soft food can be given.
