Yellowish fluid vomiting in puppies

Yellowish fluid vomiting in puppies can be attributed to two main causes:

Physiological yellow fluid vomiting, such as when a puppy has been hungry for a long time, causing excessive stomach acid secretion, thus leading to vomiting of yellow fluid.
Vomiting due to disease, such as infectious diseases like parvovirus, distemper, and coronavirus infections, as well as parasite infections and gastroenteritis.

If the puppy has a good appetite, there is usually nothing to worry about, and attention to diet can be sufficient. However, if the puppy persistently vomits yellow fluid and shows symptoms like poor spirit, loss of appetite, etc., it is necessary to consider disease causes and seek medical attention promptly.

Hunger for a long time

If a puppy is hungry for a long time, excessive stomach acid secretion can lead to vomiting of yellow fluid, which usually occurs in the morning. In this case, the owner needs to adjust the dog's diet promptly and try not to let the dog remain hungry for an extended period. Establishing a good eating habit can help alleviate this situation. If the owner feeds the dog on a regular schedule daily, the condition will gradually improve.

Infectious diseases

If a puppy hasn't been vaccinated, vomiting yellow fluid could be due to infectious diseases such as parvovirus, distemper, or coronavirus infections. This usually occurs along with symptoms like a depressed spirit, loss of appetite, diarrhea, and vomiting. If these symptoms are observed, it is recommended to immediately take the puppy to a pet hospital for examination and treatment, as viral bacterial transmission is fast and can cause significant damage to the puppy.

Parasite infections

If a puppy hasn't undergone deworming or hasn't followed a regular deworming schedule, infections from intestinal parasites like roundworms, tapeworms, and filarial worms can cause gastrointestinal disorders, leading to vomiting of yellow fluid. In some cases, the puppy may even vomit the parasites. The owner can observe the dog's vomit and feces to check for parasites. If found, it is necessary to consult a pet doctor promptly and choose an appropriate deworming medication for the dog.

Gastroenteritis

If a puppy vomits yellow fluid continuously for several days, it is likely to have contracted gastroenteritis. mild cases may involve vomiting once, but severe cases can lead to continuous vomiting for several days, along with a gradual decrease in appetite and even complete loss of appetite. Common causes of gastroenteritis in puppies include overeating, food poisoning, parasite infections, bacterial infections, and viral infections. It is recommended that the owner take the puppy to a pet hospital promptly to identify the specific cause based on the puppy's condition and examination results, then use anti-inflammatory drugs and eliminate the underlying cause.
