Vomiting in Dogs

Vomiting is common in dogs and can be acute (sudden onset), or chronic (occurs over a period of time). This page looks at the signs, the possible causes, when to see a vet, and the general care of dog vomiting.

Dog vomiting is a symptom that is, to a certain extent, quite normal. It is the immune system's way of expelling harmful foreign substances from the body. If your dog vomits once in a while but does not show any other signs of health problems, there is probably nothing to worry about. However, if your dog suddenly develops bouts of vomiting which don't seem to stop, or if the dog is suffering from chronic vomiting, a thoroughly examination is called for.

Signs of A Dog About To Vomit

Puppy There are telltale signs which show that a dog is going to vomit.

One sign is that the dog tends to lick her mouth incessantly maybe because she drools before vomiting.

Another sign is you can see obvious contraction of the stomach muscles, very often accompanied by heaving, and sometimes gagging.

Even before any of these signs are showing, when my dog Hana feels like throwing up, she always comes to me with a "sick look" on her face and her tail is way down between her legs. Her body looks stiff - perhaps due to upset stomach. So if we are observant, we most likely can tell that a dog is going to vomit.

When to See a Vet and Diagnosis of Vomiting in Dogs

If your dog suffers from chronic vomiting, or if she shows any of the following symptoms, take her to the veterinarian right away:

  • If the dog is vomiting more than 2-4 times a day.
  • If the vomit is foamy.
  • If there is blood in the vomitus.
  • If the vomitus is foul-smelling.
  • If the dog is weak or dehydrated*.
  • If the dog's belly is bloated.
  • If the dog is restless or panting, or seems to be in pain.
  • If the dog has a fever.

*To check for dehydration, pick up some skin on the back of your dog and let it drop. If the skin does not return to its original position immediately, it means dehydration.

Be prepared to answer some of these questions at the vet:

  • When did the vomiting start?
  • Did the dog vomit food or just bile?
  • Was the dog gagging or retching with no substances?
  • Has there been a recent dietary change?
  • Have you fed your dog fatty foods or table scraps?
  • Have there been recent environmental changes, e.g. have pesticides or herbicides been used in the yard? Is there a possibility that the dog has ingested rat poison, or some plants that may be poisonous to dogs?

Diagnostic tests may include:

  • An abdominal x-ray - to see if there is intestinal obstruction or bloat.
  • Blood work - to rule out poisoning, kidney or liver diseases, or pancreatitis, etc.
  • Fecal sample - to check for intestinal parasites.

Some Ways to Prevent Vomiting in Dogs

Depending on the cause of vomiting, here are some measures that can be taken to prevent vomiting in your dog:

  • If your dog often vomits in the morning or before eating and the expelled substance is a clear yellow or brownish fluid, it may mean that she has an upset stomach caused by excessive stomach acids. Feeding your dog more frequent meals in smaller portions may solve the problem.
  • If you feed your dog once a day, and your dog gulps down the food very fast because she is hungry, it is more likely that she will vomit after eating. Try feeding her several smaller meals - she may feel less hunger and may eat slower.
  • As anxiety is a cause for vomiting in dogs, make sure that your dog has no stress or anxiety in her life! For example, many dogs feel threatened and experience anxiety if they have to eat in the presence of other dogs. Therefore, letting your dog enjoy her meals in a quiet, non-threatening environment can remedy this vomiting cause.

Managing a Vomiting Dog

If your dog has mild, acute vomiting but is otherwise fine, try fasting her for 24 hours.

After 4 to 8 hours of fasting, you can give her some broth.

If she can keep the broth down, offer her a bit more food after another 8 hours. You can add a bit of well-cooked meat, and some well-cooked grains such as oatmeal or rice to the broth.

If your dog starts vomiting again, resume just feeding her broth for another 12 hours or so and try again.

If your dog is suffering from chronic vomiting, it is essential that you take her to the vet for a thoroughly check-up to find out the underlying cause.
