Mornings often seem to be hectic. From getting yourself ready for work to caring for the rest of your family and getting everyone out the door, there's a lot to do in a limited time. But if your dog throws up in the morning each day, your routine can quickly change, and you may find yourself worried about just what's going on with your dog. With a few potential causes to this issue, there are some ways that you can help to keep your dog from vomiting so frequently.

Dog throws up in morning

If your dog throws up in the morning before eating breakfast and on an empty stomach, then the cause of the vomiting may be stomach bile. The Whole Dog Journal states that dogs often vomit when their stomachs are empty for too long, and the stomach bile has likely caused irritation. In these cases, they vomit up bile and foam early in the morning before their first meal.

There are a couple of ways to solve this issue. You can feed your dog smaller, more frequent meals throughout the day to keep food in her belly. You may also want to give her a dry snack, like some dry kibble or a dog treat, just before bed, and again first thing in the morning.


Eating grass

If there's grass in your dog's vomit each morning, then you may have just found the cause of the issue. Focus on preventing your dog from eating grass for a week and see if your dog's vomiting decreases.

Eating too quickly

If your dog is vomiting after every meal, there may be another cause: Eating too quickly. According to PetSafe, dogs who bolt down their food swallow air at the same time, and that upsets their stomachs and causes them to vomit soon after they've finished a meal. Bolting food carries another health hazard besides vomiting; it can cause bloat, which can put your dog's life at risk.


To combat this issue, you may want to separate your dog from other pets during feeding time to reduce stress. You can try feeding smaller, more frequent meals throughout the day, or invest in a "slow feeder" bowl designed to slow down your pet's eating.

Dog food allergies

According to The Whole Dog Journal, even dog food may prompt vomiting. If your dog is vomiting after every meal, the ingredients in the food could be prompting the stomach upset. It's possible that your dog is allergic to an ingredient in the food, such as chicken, wheat, or soy.


Try switching your dog's food to another brand with different ingredients, but be sure to make the change gradually, since a sudden change in food can also cause stomach upset. You may also want to experiment with giving your dog a probiotic. Finding the right food can take some time and persistence on your part.

Additional causes

Sudden diet changes, stress, and even a medication's side effects may cause a dog to vomit in the morning. If you notice other symptoms along with the vomiting, such as lethargy, diarrhea, or loss of appetite, then it's time to take your dog to the vet.


According to VetStreet, there are several medical issues that can cause dog vomiting at night or in the morning. These potential causes include liver disease, toxins, pancreatitis, and parasites. Each of these issues can be quite serious, so please consult your vet if you can't get to the root of your dog's vomiting on your own.
