Why Dogs Throw Up After Eating

Quick Eating due to Anxiety

Although most pet parents assume that a dog vomiting after eating may have a sensitivity to the food, it isn't necessarily the case. Anxiety or fear may be the driving force to why a dog throws up after eating. Does your dog compete with other dogs in the house for food? Their sense of territory can make them eat faster, which may overload their stomach and decrease the amount of saliva normally swallowed with the food that acts as a buffer. Just like us, nervousness and stress can make your dog feel queasy and increase acid in the stomach.

When dogs eat too quickly, they don't take the time to chew the larger pieces of kibble. They also ingest a significant amount of air, both of which can come back up by regurgitation or by vomiting. If possible, feed your anxious dog in a secluded area, without any other animals around. Start with small meals and gradually build back up to a normal-sized dinner.

There can be other underlying issues associated with a dog's anxiety that can affect their ability to keep food down. Has there been changes in the house that might have disrupted their routine? Have you moved recently or changed your work schedule? Changes like this can make your dog anxious, which can affect the digestive system. If you suspect that something like this could be why your dog is throwing up after eating, continue to show your love. Give praise, pet and play with them, and reassure them that everything is okay. Slowly, over time they will adapt to the changes and get back to their old self. It is still important to monitor eating habits to make sure that there isn't a larger issue at hand–if it is happening more than once every few weeks, you should consult your veterinarian. Vomiting due to other health concerns is more common than due to anxiety.

He Loves the Taste

Similar to anxiety eating, your dog may eat too fast if they love the taste of the food. There's nothing wrong with enjoying a meal, but you want to be sure your dog gets all the nutrition they can get without it coming back up.

One way to reduce this tendency is by feeding smaller portions until you notice their intake has naturally slowed down. Another option is to serve your dog's meals spread out on a large flat plate or baking sheet. This forces your dog to take longer to locate and ingest each piece, reducing the chances of vomiting after eating. There are also special dog food puzzle toys that require dogs to work a little harder to get the food out. Just be sure to monitor they still eat all of the food, and doesn't get frustrated by the new meal delivery system.

He Recently Ingested Grass

While dogs may eat grass for a variety of reasons with no adverse effects, dogs that aren't feeling well for other reasons may eat grass and vomit, possibly removing whatever made them sick. Once your dog vomits the grass and food, they should feel better and shouldn't need any additional medical care, if it’s just a simple upset stomach. Remember to keep your dog hydrated and watch closely to ensure vomiting doesn't persist, and that there is nothing else wrong.

If your dog simply cannot stop vomiting after eating food and grass, see your vet or emergency clinic as soon as possible. There could be something else wrong and whatever the cause, quick attention will make your dog feel better.
