You should go to the hospital for an examination. After the cause is diagnosed, you can choose a specific treatment plan based on the doctor's advice. If vomiting is caused by gastroenteritis, such as gastroenteritis, intestinal obstruction, tumor, etc., surgery is often required for treatment. If your dog vomits out incompletely digested food and eats the dog food back after vomiting it out, it is generally physiological vomiting, similar to rumination.

What to do if a dog vomits:

1. Fasting. If a dog vomits, it means there is gastrointestinal discomfort or indigestion. It should be fasted immediately to avoid Secondary vomiting and diarrhea.

2. When there are hairs in the vomit, comb the dog's hair more often. It doesn't matter if the dog eats grass appropriately. It can induce vomiting on its own. Hair removal cream is not exclusive to cats. Dogs can also eat it.

3. Send to the hospital in time. When a dog vomits seriously, it is 80% due to food poisoning or acute illness, and it needs to be sent to the hospital for physical examination and treatment immediately.
