No pet owner wants to ever think about their canine companion having cancer. However, research shows that one in every three dogs has cancer within their lifespan. If identified early, approximately half of most dog cancer can be treated. Hence, it is of utmost importance to learn the common symptoms of cancer in canines. That being said, many diseases, not only cancer, can have the same symptoms, and these symptoms can differ depending on the form of cancer.

Here, we cover more about dog vomiting and whether or not it could be a sign of cancer. Read on to find out more!

What is vomiting in dogs?

Vomiting in dogs is not necessarily a sickness but a sign that points to an underlying condition such as dog cancer. It begins with nausea, then retching and dry heaves before vomiting.

The first sign that your pet is nauseated is excessive drooling. Retching lets your pet expel intestinal and gastric content, debris, fluid, and food out through the mouth. On top of that, vomiting may lead to acid-base balance upset, electrolyte depletion, and perhaps, pneumonia.

On the other hand, don’t mistake regurgitation for vomiting. Regurgitation is the ejection of things from the esophagus. Usually, regurgitation happens when the item expelled from the dog’s mouth is indigestible food overlaid in mucus.

What’s more, your pet can regurgitate without retching and nausea. It happens when they consume too much water or food.

Why is my canine companion vomiting?

Vomiting can be caused by a number of reasons, though the most common one is that they consumed something wrong, from garbage and fabrics to a carcass and toys. While this list is worrying, it’s not a big deal since they should be okay after throwing up.

Other reasons why your dog could be vomiting include:


  • Acid reflux
  • Change in diet
  • Drinking or eating fast
  • Cancer
  • Intestinal parasites
  • Some viruses
  • Side effects from medication
  • Liver failure
  • Bacterial infections
  • Pancreatitis
  • Bloat
  • Poisons and toxins

Even though vomiting could be a sign of canine cancer, it’s very rare. However, if your pooch is also losing weight fast, his vomiting should be a cause for concern.

So, when should you worry after your pet begins vomiting?

When your dog vomits once or twice, it’s rarely a reason to be worried. Nevertheless, if he continues vomiting more than three times a day or vomits once daily for several days, it’s time to begin worrying and consult your veterinarian.

Here’s when you should call a veterinarian:

  • Your pooch vomits 4 to 5 times daily
  • The pet vomits continuously for several days
  • Your pooch is attempting to throw up, but nothing comes out
  • The vomit contains blood
  • There are other signs of sickness other than vomiting

Another reason to be worried is when your pet looks sick or has different symptoms. Here are the other signs to look out for:

  • Dehydration
  • Losing weight
  • Diarrhea
  • Swollen or distended abdomen
  • Pale gums
  • Abdominal pain

Vomiting for dogs with cancer

As mentioned previously, vomiting is not a common dog cancer symptom, though it should be a cause for alarm if a pet with cancer vomits. This might be because of all the torture cancer puts his body through. Nonetheless, it could also be a cancer medication side effect.

So, if your pet with cancer throws up, think of any diet changes or any other adjustments that were recently made:

  • Is he taking new medicine?
  • Did you switch his diet or integrate a different supplement?
  • Or did he recently begin chemotherapy?

These are among the common reasons why a dog with cancer could be vomiting. Talk to your vet about these concerns.

Nevertheless, if your pet is already taking anti-nausea medicine, he should not be vomiting. Hence, whatever the cause for his vomiting is, it overrides his medication.

Home remedies for dog vomiting

  • Reducing the amount of food he consumes lets his digestive tract recover. All the same, don’t leave him starving and avoid overfeeding him also.
  • Additionally, ice chips can reduce dehydration as a result of throwing up
  • You can also incorporate ginger in his meals as it features carminative properties, which offer stomach relief. That being said, most pets don’t like the taste of ginger; therefore, it would help if you blend it with coconut milk. Another clever way is to use ginger powder and honey on a slice of bread.
  • Switch to a bland diet; plain meat, plain chicken, or white rice will do.
  • Add chicken broth to your pet’s diet, as it will come in handy in countering dehydration. It would be best to prepare it at home since the store-bought versions could have harmful additives.

Diarrhea and throwing up are the two most common issues that lead a pet parent to consult a veterinarian. Pooches usually enjoy eating all the things they should be avoiding, which could result in stomach problems. But, if your pet isn’t vomiting at a severe rate, you can deal with their symptoms at home.
