What is going on when a dog vomits and has diarrhea?

Dog vomiting and diarrhea may be caused by infectious diseases, gastritis, parasite infections, and other reasons. First, if the dog is young and has not been vaccinated, the possibility of infectious diseases should be considered. It is best to go to a pet hospital for testing, or buy test papers to test the dog at home, to rule out infectious diseases. Secondly, if infectious diseases are ruled out, it is possible that gastritis is causing the problem. Treatment includes using antibiotics, gastroprotectants, and probiotics. Additionally, if parasites are seen in the dog's vomit and feces, the possibility of a parasite infection should be considered.

Infectious diseases

When a dog shows symptoms of vomiting and diarrhea, and its vaccines have not been fully administered, it is suspected to be caused by infectious diseases, such as coronavirus, parvovirus, and distemper virus. These infections will cause vomiting and diarrhea, accompanied by depression, loss of appetite, fever, and coughing. If your dog shows these symptoms, take it to a pet hospital immediately to diagnose and avoid delays in treatment.

Gastritis

A dog with gastritis will also exhibit obvious vomiting and diarrhea, and even bloody stools. This may be due to the food usually fed or caused by the dog eating something it shouldn't. To deal with this, the owner can stop feeding the dog and giving it water for a period of time to see if the situation improves. If it does, slowly introduce softened dog food in small amounts. If there is no improvement, it is recommended to go to the pet hospital for diagnosis and treatment as soon as possible.

Parasite infection

If the owner has not given the dog regular deworming for a long time, the dog may vomit and have diarrhea after becoming infected with parasites. This may also be accompanied by a decrease in appetite and gradual weight loss. Sometimes, worms can be seen in the vomit and feces. To deal with this, the owner should take the dog to a pet hospital for a fecal examination to identify the specific parasite species. Then, use appropriate internal deworming drugs for treatment. To prevent dogs from becoming infected with parasites, owners should regularly deworm their dogs. Internal deworming should be done every three months, and external deworming every month.
