What should I do if my dog has diarrhea and vomits white foam?

Diarrhea and vomiting white foam in dogs may be caused by gastroenteritis, parasite infection, infectious diseases, poisoning, and other reasons. I recommend that owners first observe a fasting period. If the dog does not vomit or have diarrhea again, there should be no major problems, and you can consult a pet doctor for medication treatment. However, if the dog's condition worsens, accompanied by decreased appetite, depression, sleepiness, and other symptoms, you should immediately take the dog to a pet hospital for inspection. Otherwise, continuous diarrhea can lead to dehydration in the dog, and in severe cases, it can even pose a threat to its life.

Gastroenteritis

When a dog has gastroenteritis, the most obvious symptoms are diarrhea and vomiting. In the early stage, the dog's excrement is mostly a liquid with a foul smell. In the later stage, there will be blood and foam in the feces, which may also be mixed with mucus. Generally, a dog with gastroenteritis cannot recover on its own, so it is necessary to take the dog to the pet hospital for IV treatment in time, or else the dog's condition will worsen.

Parasite Infection

It is necessary to give dogs an internal deworming every three months and an external deworming every month. If the dog is not dewormed on time, the dog's internal parasites will cause diarrhea and vomiting white foam. Owners can pay attention to observe the dog's vomit and diarrhea to see if there are parasites. If there are parasites, it confirms an internal parasite infection, and it is necessary to deworm the dog promptly.

Infectious Diseases

If a dog is not fully immunized and has symptoms such as depression, loss of appetite, and fever, it may be infected with infectious diseases such as canine parvovirus and canine distemper. These diseases often show symptoms such as vomiting and diarrhea in the early stage. The mortality rate of these infectious diseases is high, so it is best to take the dog to the pet hospital for inspection and treatment in time.

Poisoning

If a dog accidentally eats toxic substances, such as pesticides containing organic phosphorus or isoniazid, it may cause poisoning, leading to symptoms such as diarrhea and vomiting white foam. In addition, if a dog accidentally eats highly irritating liquids, such as 84 disinfectant, it can also cause intestinal reactions such as vomiting white foam. If the dog's symptoms are severe, you must take it to a pet hospital for inspection and treatment in time.
