Why is the puppy vomiting white foam? Puppies vomiting white foam may just eat bitter food, or it may be caused by indigestion, poisoning, gastroenteritis, infectious diseases, parasites, etc. For this situation where the puppy vomits white foam, if the puppy vomits foam only once or twice a day and is in good spirits, you can first observe the dog's vomiting by fasting food and water, and then deal with it. However, if the vomiting symptoms continue to worsen or the vomiting frequency is frequent, you need to go to the pet hospital for examination and treatment in time.

1. Eating bitter food

Dogs like sweet food. If they eat bitter food, their salivary glands will be stimulated to secrete a large amount of mucus, resulting in vomiting of white foam. In this case, the dog generally does not have abdominal contractions, and the main reason is that there is a lot of white foam in the mouth, which is normal. The owner can use mouthwash to rinse the dog's mouth, and it usually recovers in a few minutes.

2. Indigestion

If your dog eats too fast, or eats cold, spicy, and difficult-to-digest food, he may suffer from vomiting due to indigestion. In this regard, the owner needs to change the dog's digestible food and feed the dog some pet-specific probiotics to help digestion.

3. Poisoning

If the puppy is vomiting white foam and is accompanied by convulsions, conjunctival cyanosis, etc., it is likely to be poisoned. At this time, it is recommended that the owner promptly remove the saliva from the puppy's mouth to prevent the puppy from developing aspiration pneumonia or suffocation due to coughing, and then promptly send the puppy to a nearby pet hospital for first aid.

4. Gastroenteritis

If the puppy accidentally eats expired, spoiled or human food, it will irritate the gastrointestinal tract and cause acute gastroenteritis, which will cause vomiting, foaming and diarrhea. At this time, you need to take the dog to the pet hospital for examination in time, and then fast and water infusion treatment.

5. Infectious diseases

Because the puppy is still young and has not yet been vaccinated, when vomiting white foam occurs, infectious diseases should be considered, such as canine distemper, parvovirus, coronavirus, etc. It may also be accompanied by symptoms such as diarrhea, high fever, cough, lethargy, and loss of appetite. In this regard, it is recommended that owners conduct a parvoantigen test on their dogs. After diagnosis, timely symptomatic treatment is required.

6. Parasites

If the dog has not been dewormed recently, you need to consider that the white foam in vomiting may be caused by parasites. In particular, roundworms can migrate from the intestines to the stomach, and vomiting symptoms will occur when the parasites mechanically stimulate the stomach wall. Owners can observe carefully and if they find parasites in their dog’s vomit or feces, they need to deworm them as soon as possible.
