Can Dogs Eat Their Own Vomit

Yes, dogs can eat their own vomit without causing harm to their health. While it may seem unappealing to humans, this behavior is natural for dogs as they have evolved to clean up their environment and prevent the spread of parasites. However, consistent vomiting could be a sign of an underlying health issue, and if this is the case, it’s important to consult a veterinarian to address the problem.

Can Dogs Eat Their Own Vomit

As unpleasant as it may sound to us humans, some dogs will eat their own vomit from time to time. While this behavior may catch pet parents off guard, it’s actually not uncommon in the canine world. In this blog post, we delve into the reasons why dogs eat their own vomit and discuss what, if any, precautions should be taken in response to this behavior.

Why Do Dogs Eat Their Own Vomit?

There are several reasons why dogs eat their own vomit, which can range from natural instincts to health issues.

Natural Instincts

Dogs are opportunistic feeders, and their ancestral wild counterparts would eat whatever they could find to survive. Eating their vomit can be linked back to their instincts to clean up their surroundings and prevent the spread of parasites. Moreover, regurgitation, which is different from vomiting, is often practiced by mother dogs to feed their puppies by regurgitating semi-digested food.

Hunger or Boredom

Some dogs may eat their vomit because they’re hungry or bored. A dog that isn’t receiving enough dog food or mental stimulation might resort to eating its vomit as an extra meal or to alleviate boredom. Be sure to provide a balanced diet, regular exercise, and mental stimulation to keep your pup content.

Digestive Issues or Health Problems

Dogs may also eat their vomit if they’re experiencing digestive issues or other health problems. Eating too quickly, food intolerances or allergies, and gastrointestinal issues can all lead to vomiting, and your dog may eat their vomit in an attempt to re-digest their food. If you’re concerned about your dog’s health or notice an increase in vomiting frequency, consult your veterinarian.

Precautions and Preventative Measures

While eating their vomit might be natural for dogs, it’s still a good idea to take some precautions and implement preventative measures to mitigate the behavior.

Monitor Your Dog’s Diet

Paying attention to your dog’s diet can help prevent vomiting in the first place. Make sure your dog is eating a high-quality, balanced dog food, and avoid overfeeding them. Additionally, refrain from giving them foods that are known to cause digestive issues in canines.

Feed Smaller, More Frequent Meals

If your dog is prone to eating their own vomit or tends to gulp down their food quickly, consider feeding them smaller, more frequent meals. This can help reduce the likelihood of vomiting due to gastrointestinal issues caused by rapid food consumption.

Improve Mental Stimulation

By providing your dog with regular exercise, engaging toys, and interactive playtime, you can help keep them mentally stimulated and less likely to engage in undesirable behaviors such as eating their vomit.

Keep a Close Watch and Clean Up Immediately

If your dog does vomit, try to clean up the mess as quickly as possible. This can help mitigate the temptation for your dog to eat their vomit and prevent the behavior from becoming a repeated pattern.

When to Seek Veterinary Attention

While eating vomit is a normal behavior for dogs, it’s essential to monitor your dog closely and consult a veterinarian if you notice any concerning signs or an increase in vomiting frequency. Some potential red flags that warrant a visit to the vet include:

  • Persistent vomiting or diarrhea
  • Weakness or lethargy
  • Loss of appetite
  • Signs of pain or distress
  • Blood in the vomit

Remember, your veterinarian is your best resource for understanding your dog’s health and addressing any specific concerns related to their wellbeing.

Understanding the Difference Between Vomiting and Regurgitation

While the two might seem similar, vomiting and regurgitation are different processes that can occur in dogs. Understanding the differences can help you determine the cause and take appropriate action to address your dog’s health.


Vomiting is the forceful expulsion of stomach contents through the mouth, usually accompanied by signs of discomfort or distress in your dog. Vomiting can have many causes, including dietary indiscretion, gastrointestinal issues, infection, or a toxic substance ingestion.


Regurgitation is the passive, effortless expulsion of swallowed food or liquid from the esophagus before it reaches the stomach. This process can happen with little to no warning and may appear as if your dog is simply “spitting up” their food. Regurgitation can occur due to esophageal issues, eating too quickly, or other underlying health problems.

Recognizing Potential Dangers of Eating Vomit

While it’s generally safe for dogs to eat their own vomit, there are specific situations in which consuming vomit may pose a risk to their health.

Foreign Objects

If your dog has swallowed a foreign object, such as a toy or a bone, and vomited it up, it’s essential to prevent them from eating the vomit and potentially swallowing the foreign object again. This can lead to obstruction or injury in their gastrointestinal tract.

Toxic Substances

If your dog has ingested a toxic substance and vomited it up, eating their own vomit can result in the re-ingestion of the toxin. In such cases, it’s crucial to keep a close watch on your dog, clean up the vomit immediately, and seek veterinary attention for proper treatment.

Final Thoughts

Although it can be unpleasant to witness, it’s usually safe for dogs to eat their own vomit. As a responsible pet owner, it’s essential to monitor your dog’s health, take necessary precautions and preventative measures, and consult a veterinarian if you’re concerned about their wellbeing. By doing so, you can help ensure a happy, healthy, and well-cared-for canine companion.
