Is your dog puking in the morning? This happens from time to time, but frequent vomiting necessitates immediate medical attention. It is normal for dogs to vomit, but the colour of the vomit may vary from time to time, which can be concerning for most dog owners. It can be clear, yellow, red, or even brown, but each colour has a different meaning.

So, why does my dog vomit first thing in the morning? There are several reasons for this, but a dog with an upset stomach is a bad dog. Your dog’s vomiting in the morning is caused by an upset stomach. Dogs who are fed once a day may vomit in the morning because there are long periods between meals, which can cause bile vomiting.

You are right to be concerned about your dog as a dog owner. Today, in this article, I will discuss all of the possible causes of your dog throwing up and how to resolve this troubling issue.

Why does my dog throw up yellow bile in the morning?

If you notice that your dog’s vomit is yellow in colour, it usually contains bile or digestive fluid that foams and contains bile produced by the liver. This yellow foam usually indicates that its stomach is empty and the bile is irritating the stomach. This can cause stomach pain in your dog.

This could be due to a variety of factors such as having an empty stomach for an extended period of time, eating grass, or having food allergies. This is concerning and should be addressed by every dog owner for the sake of their canine companion.

However, if your dog throws up all the time, you should consult with your veterinarian as soon as possible to rule out any medical issues that could be serious.

Why does my dog vomit in the morning?

1.Empty Stomach

Dogs frequently vomit when they have an empty stomach for an extended period of time due to stomach acids causing discomfort and irritation. Affected dogs typically vomit bile and foam in the early morning hours but otherwise appear normal.

2.Eating Grass

If you notice your dog vomiting after eating grass, he is suffering from Nutritional Deficiency. When dogs eat unusual and non-food items (such as grass), it indicates that your dog is not getting enough vitamins, minerals, fibre, or chlorophyll. This causes vomiting.

It is critical that you keep your dog away from grass in public parks and along roadsides—anywhere that may have been treated with chemical pesticides, herbicides, or exposed to environmental toxins and/or fertilisers.

3.Eating Too Quickly

If your dog eats too quickly for any reason, such as excitement for food, it can result in vomiting in the morning due to not properly chewing the food while eating.

Worryingly, a dog’s fast eating can result in choking, gagging, vomiting, and an even more serious disease known as Gastric Dilation (colloquially known as canine bloat).

4.Food Allergies

If your dog vomits after every meal, you’re probably feeding him something he’s allergic to, such as chicken or soy. It’s possible that your dog is allergic to one or more of the ingredients in the food.

Food intolerances in your dog’s system can cause discomfort and irritation, resulting in an upset stomach. It may cause diarrhoea and vomiting.

5.Drinking Too Much Water

If your dog drinks contaminated water, he may vomit. Bacteria, blue-green algae, and parasites in dirty water can upset your dog’s stomach and make him sick.

6.Medical Cause

Certain diseases can cause vomiting in the early morning. In dogs, bilious vomiting syndrome (BVS) causes vomiting caused by bile buildup irritating the stomach lining. When the dog’s stomach is empty, bilious vomiting usually occurs in the morning or late at night.

How to stop my dog from throwing up in the morning?

1.Change Your Dog’s Food

If your dog is frequently vomiting after every meal, changing his food may be beneficial because he may be allergic to some of the ingredients in his food, which is causing the vomiting.

Don’t make drastic changes to your dog’s food; instead, make gradual changes because a sudden change in food can cause an upset stomach.

2.Consult Your Veterinarian

Don’t make drastic changes to your dog’s food; instead, make gradual changes because a sudden change in food can cause an upset stomach.

If your dog is vomiting and exhibiting symptoms such as loss of appetite, diarrhoea, or body pain, you should seek the advice of your veterinarian as this could indicate potential toxicity in your dog’s system.

3.Small Meal Before Bedtime

Another way to keep your dog from vomiting is to give him a small meal or a treat before bedtime. This way, he won’t sleep on an empty stomach and will be less likely to vomit in the morning.

This should help settle the stomach and, in the long run, solve the problem because acid production will be reduced.

4.Buy A Slow Feeder

You can buy a slow feeder if the vomiting is occurring due to his habit of eating fast because of any reason. A slow feeder will not only avoid vomiting but also help your dog to eat his food slowly with more chewing.

You can buy a slow feeder for your dog on Amazon which is of good quality and has a reasonable price.

Some of the recommendations are:


This will help prevent vomiting early in the morning. Famotidine and omeprazole are common over-the-counter antacids used in dogs to treat bilious vomiting. They usually only need one dose per night to avoid the joys of early morning vomit piles.

However, it is important to note that not all early morning vomiting is caused by a buildup of stomach acid, so please consult your veterinarian before assuming antacids are the appropriate treatment.

6.Reduce Time Between Meals

Reduce the time between meals and make sure your dog gets at least two meals per day, with the second meal served after 7 p.m. When dogs are only fed once a day, the stomach may remain empty for an extended period of time, resulting in bilious vomiting syndrome.

When you should be concerned about your dog throwing up?

If your dog is throwing up more often then you should consult your veterinarian. 

If an examination of your dog’s vomit reveals potential toxicity, seek immediate veterinary attention. You should also seek medical attention if your dog vomits multiple times in one day or for more than 24 hours in a row.

If your dog exhibits these symptoms, you should take him to the vet.

Symptoms may include:

  • Frothy yellow vomit
  • Vomiting usually occuring in the morning or late at night
  • Depression
  • Lethargy
  • Drooling
  • Licking his lips
  • Lack of appetite
  • Concentrated urine, pale gums, sunken eyes, and loss of skin elasticity are signs of dehydration

Can stress cause a dog to vomit?

We all deal with stress from time to time, but did you know your dog can feel the effects as well? Stress can make your dog sick, resulting in vomiting. Dogs cannot communicate with you, but they show signs of stress and illness. Vomiting indicates that something is wrong with your dog’s health and should be addressed as soon as possible.
