What happens when a dog has an upset stomach?
Expert Answer
If a dog’s stomach is upset, it may show vomiting, diarrhea, abdominal pain, poor appetite, bad breath, and reluctance to move. When the stomach is uncomfortable, the dog may lie on the ground, arch its back, avoid moving, and resist having its belly touched.
If these symptoms appear, first withhold food to avoid further irritating the stomach and adding to the digestive burden.
An upset stomach can be caused by gastritis, a foreign-object blockage, an infectious disease, or parasite infection. It is best to take the dog to a vet promptly to determine the exact cause and begin treatment.
