The reasons why Corgi spits out dog food:

1. He doesn’t like this dog food. If you suddenly change a new dog food to your Corgi and your Corgi vomits the food, it is probably because he doesn't like the taste of the new dog food and will spit it out after a few bites.

2. Eating too fast. If a Corgi eats too quickly, it will cause reflux symptoms.

3. Gastrointestinal diseases. When a Corgi suffers from gastrointestinal disease, he will become particularly uncomfortable, lose his appetite, and may vomit dog food.

4. I’m full. If the owner does not control the amount of food, and the Corgi is very hungry at this time, it will keep eating until it fills itself up, and it will also vomit dog food at this time.

5. Infectious diseases. If Corgi is infected with infectious diseases such as parvovirus and canine distemper, he will also vomit dog food.
