What Colour Vomit is Concerning?

Red or Dark Brown: If you notice red or dark brown vomit, it could indicate the presence of blood. This could be due to various reasons such as gastrointestinal bleeding, ingestion of foreign objects, or other internal issues. It's important to seek veterinary attention promptly.

Yellow or Green: Vomit that is yellow or green could suggest the presence of bile. Bile is a digestive fluid produced by the liver, and excessive vomiting of bile could indicate issues with the dog's digestive system or liver.

Blue or Green: These colors could suggest that your dog has ingested something toxic. Certain chemicals or poisons can cause vomiting with unusual colors.

Remember, symptoms such as lethargy, diarrhea, loss of appetite, or changes in behavior should also be taken into consideration when assessing your dog's health.

However, It doesn't matter what color the vomit is. If it becomes frequent or is accompanied by other symptoms, it's worth checking with a vet.

What to Give a Dog for Upset Stomach and Vomiting?

1. Medications

Over-the-counter medications and dosages can vary based on the dog's weight and health status.

Here are some common antiemetic drugs that might be prescribed for dogs:

  • Cerenia (Maropitant): Cerenia is one of the most commonly prescribed antiemetic drugs for dogs. It is effective in preventing vomiting caused by a variety of factors, including motion sickness, chemotherapy, and various medical conditions. It comes in both injectable and oral forms.
  • Metoclopramide (Reglan): Metoclopramide is another antiemetic drug that works by enhancing the movement of the stomach and intestines. It can be used to manage vomiting and to aid in motility disorders of the gastrointestinal tract.
  • Ondansetron (Zofran): Ondansetron is a medication often used to manage vomiting and nausea associated with chemotherapy. It is sometimes used off-label for dogs, but its use should be determined by a veterinarian.
  • Dolasetron (Anzemet): Dolasetron is another medication that can be used to manage vomiting, particularly in cases of chemotherapy-induced nausea and vomiting.
  • Dimenhydrinate (Dramamine): While not a prescription medication, dimenhydrinate is an over-the-counter medication sometimes used to manage motion sickness in dogs. Its use should be discussed with a veterinarian to determine the appropriate dosage.
  • Cimetidine: Helpful for the gastrointestinal movement, neutralizing gastric acid
  • Acepromazine: Acepromazine is an anti-nausea and sedative medication that might be used in some cases, although it's not primarily an antiemetic. It can help calm anxious dogs and reduce the risk of vomiting due to anxiety or motion sickness.

2. Bland Diet

After the fasting period, you can start feeding your dog a bland diet. A common option is boiled white rice and boiled, skinless, boneless chicken in equal parts. This is easy on the stomach and can help firm up the stool. You can also consider using commercial bland diets formulated for upset stomachs, which are available at pet stores and veterinary clinics.

3. Hydration

Make sure your dog has access to clean and fresh water at all times. Dehydration can worsen the situation, so encourage your dog to drink.

Tips for Encouraging Your Dog to Drink Water

  • Ice Cubes: Some dogs find ice cubes fun to play with and lick. You can add ice cubes to their water bowl to make it more enticing, especially during hot weather.
  • Water Fountain: Some dogs are attracted to running water. Consider using a water fountain designed for pets, as the sound and movement of the water can encourage them to drink.
  • Flavor Enhancers: In consultation with your veterinarian, you can add a small amount of low-sodium chicken or beef broth to your dog's water to make it more appealing. 

Vomiting in Dogs When to Worry?

While occasional vomiting might not be a cause for immediate concern, there are certain situations where you should be vigilant and consider contacting a veterinarian:

  • Vomiting persists for more than 24 hours
  • Blood in your dog's vomit
  • Lethargic, weak
  • Dry gums, sunken eyes, and decreased skin elasticity
  • Ingested something toxic
  • Diarrhea, fever, abdominal pain

How to Treat and Prevent Vomiting in Dogs?

The vet may recommend blood tests, X-rays, ultrasounds, or other diagnostic procedures to identify the underlying cause of the vomiting.

If your dog is dehydrated from vomiting, the veterinarian may administer fluids intravenously or subcutaneously to rehydrate them.

In some cases, the vet might recommend a brief fasting period to give the digestive system time to settle down.

In severe cases, surgery might be required if there is a physical obstruction or other serious gastrointestinal problem.

Schedule regular check-ups and deworming with a vet.

Here is a general guideline for deworming dogs:

  • Puppies: Puppies should be dewormed starting at two weeks of age, and the process should be repeated every two weeks until they are around 8 weeks old. After that, they should be dewormed once a month until they reach six months of age.
  • Adult dogs: Once a dog reaches six months of age, a regular deworming schedule is typically recommended every three to six months, depending on the risk factors in their environment and lifestyle.
  • Pregnant and nursing dogs: Pregnant dogs should be dewormed before giving birth to reduce the risk of transmitting worms to the puppies. Nursing dogs should also be dewormed to prevent the transfer of worms through their milk.

The specific deworming medication can vary depending on the type of worms that need to be treated. Common deworming medications for dogs include:

  • Pyrantel pamoate: Effective against roundworms and hookworms.
  • Fipronil: Effective against scabies mites, adults, larvae, ticks, fleas, lice, and eggs.
  • Albendazole: Effective against various types of worms, including roundworms, hookworms, whipworms, and certain protozoa.
  • Milbemycin oxime: Effective against heartworms, roundworms, hookworms, and whipworms.
  • Abamectin B1: Effective against heartworms, intestinal worms, and some external parasites.

Is It Bad If a Dog Eats Its Own Vomit?

In most cases, if a dog eats a small amount of their own vomit, it's not necessarily harmful. Dogs have a natural tendency to scavenge and may ingest their own vomit out of curiosity or instinct. While a small amount of a dog's own vomit is unlikely to cause immediate harm, it's important to maintain good hygiene. Vomit can carry bacteria and viruses, so it's best to clean up the area promptly to reduce the risk of infection.

Is Dog Vomiting Blood An Emergency?

Yes, if your dog is vomiting blood, it is considered a medical emergency. Vomiting blood, known as hematemesis, can be a sign of serious underlying health issues, such as gastrointestinal bleeding, ulcers, or ingestion of a foreign object. 

Why is My Dog Throwing Up Blood But Acting Normal?

While it's concerning to see a dog vomiting blood, they may appear normal between episodes if the bleeding is intermittent or if the blood is coming from a relatively minor issue, such as irritation in the throat or mouth. However, it's crucial to have your dog examined by a veterinarian to identify the underlying cause, as even minor bleeding can be a symptom of a more significant problem.

How to Clean Dog Vomit Carpet?

To clean dog vomit from a carpet, follow these steps:

Remove as much of the solid material as possible using gloves and a plastic bag.
Blot the area with paper towels to absorb excess liquid.
Mix a solution of equal parts white vinegar and water or use a pet-safe enzymatic cleaner.
Apply the solution to the affected area and let it sit for a few minutes.
Blot the area again with clean paper towels until the stain and odor are removed.
Rinse the area with clean water and blot dry.

Why is My Dogs Vomit Yellow?

Yellow vomit in dogs can be due to various reasons, including the presence of bile. Bile is a digestive fluid produced by the liver and stored in the gallbladder. If a dog vomits yellow or greenish-yellow material, it may indicate that the stomach was empty, and the bile is being expelled. However, persistent yellow vomit can also be a sign of gastrointestinal issues, so it's essential to consult with a veterinarian for proper evaluation.

Why do Dogs Eat Grass and Vomit?

Dogs may eat grass for various reasons, including stomach upset or discomfort. Eating grass can induce vomiting and may help them remove something irritating from their stomach. However, if your dog frequently eats grass and vomits, it's essential to address the underlying cause, which could be dietary, medical, or behavioral.

Will Vinegar Kill Dog Vomit Fungus?

Vinegar has some antifungal properties and can help clean and disinfect areas contaminated by vomit. However, it may not effectively kill all types of fungi or spores. To thoroughly clean and disinfect areas contaminated with dog vomit, it's advisable to use a pet-safe enzymatic cleaner or a disinfectant recommended by your veterinarian.

Do Dogs Vomit When in Heat?

Vomiting is not a typical symptom of a dog being in heat (estrus). Dogs in heat primarily experience changes in their reproductive cycle, such as behavioral changes, swollen vulva, and a bloody discharge. Vomiting in a female dog may be due to other health issues and should be evaluated by a veterinarian.

How Long to Wait to Feed Dog After Vomiting?

After a dog has vomited, it's generally recommended to withhold food for at least 12 to 24 hours to give their stomach a chance to settle. Offer small sips of water during this time to prevent dehydration. If the dog does not vomit again during this period, you can gradually reintroduce a bland diet (e.g., boiled chicken and rice) in small portions. If vomiting continues or worsens, consult with a veterinarian.


The Dog Vomit Color Chart serves as a valuable reference tool for dog owners to better understand potential health issues their furry companions might be experiencing. However, it's crucial to remember that vomiting can have numerous causes, ranging from minor to severe. If you're ever in doubt or concerned about your dog's well-being, don't hesitate to seek professional veterinary advice. Regular check-ups, a balanced diet, and a watchful eye over your dog's behavior can go a long way in maintaining their health and happiness.
