Vomiting in Dogs: Causes & When to Worry

Many factors could cause your dog to begin vomiting. Today, our Los Angeles vets provide some information about vomiting in dogs, what to do if your dog begins vomiting, and how to induce vomiting in dogs if necessary.

Why Dogs Vomit

Vomiting is a common sign of an irritated stomach and inflamed intestines, or gastrointestinal upset in dogs.

While vomiting in dogs is an unpleasant and distressing experience for almost every dog owner, it is your pet's way of emptying their stomach of indigestible material to prevent it from remaining in their system or reaching other areas of their body.

Causes of Vomiting in Dogs

Several things can cause vomiting and diarrhea in dogs, and sometimes even a healthy pup will fall ill for no apparent reason and recover quickly.

It's possible that your dog ate too quickly, ate too much grass, or ate something that upset their stomach. This type of vomiting may occur only once and be unaccompanied by other symptoms. So, vomiting in dogs isn't always a cause for concern.

That said, potential causes of acute vomiting (sudden or severe) can be related to diseases, disorders, or health complications such as:

  • Heatstroke
  • Ingestion of poisons, toxins, or food
  • Bloat
  • Reaction to medication
  • Bacterial or viral infection
  • Kidney or liver failure
  • Pancreatitis
  • Change in diet

When To Worry About Vomiting in Dogs

Vomiting may be cause for some concern and constitute a serious veterinary emergency if you see any of these signs:

  • Seizures
  • Chronic vomiting
  • Continuous vomiting
  • Bloody diarrhea/vomit
  • Vomiting in conjunction with other symptoms such as lethargy, weight loss, fever, anemia, etc.
  • Suspected ingestion of a foreign body (such as food, objects, children’s toys, etc.)
  • Vomiting a lot at one time
  • Vomiting with nothing coming up

Chronic Vomiting

If your dog has been vomiting frequently or if it has become a long-term or chronic problem, you should be concerned, especially if you have noticed symptoms such as abdominal pain, depression, dehydration, blood, poor appetite, fever, weakness, weight loss, or other unusual behaviors.

Long-term, recurrent vomiting can be caused by:

  • Cancer
  • Liver or kidney failure
  • Uterine infection
  • Constipation
  • Intestinal obstruction
  • Colitis

As a cautious pet owner, it’s always best to prioritize safety and caution when it comes to your pup’s health. The best way to learn whether your dog’s vomiting is normal or not is to contact your vet.

What To Do If Your Dog Won't Stop Vomiting

Based on your pup's medical history and recent activities, your veterinarian will need your assistance in determining the cause of the vomiting. You may be able to provide vital information that will assist your veterinarian in determining the source of the problem and effectively treating it.

How to Induce Vomiting in Dogs

Panicked owners frequently Google "how to induce vomiting in dogs." Toxins cause gastrointestinal distress, but they can also cause serious harm when absorbed into the bloodstream and then into the tissue. The goal of decontamination is to remove the toxin from the body before it becomes absorbed. Toxicity may be avoided if vomiting is induced before the toxin is absorbed by the intestines.

That said, dog owners should know that inducing vomiting at home is not advised except under extreme circumstances!

In addition, this should always be done under the guidance of a licensed veterinarian. Before taking this action, call your primary veterinarian or a veterinary poison control center for advice.

Deciding whether your pooch should be induced at home depends on what and how much your dog has consumed, and how much time has passed - there's a chance that the substance or amount consumed wasn't toxic, so inducing vomiting wouldn't be necessary.

Though vomiting can safely bring most toxins up, a few will cause more damage by passing through the esophagus a second time by moving through the GI tract. These include bleach, cleaning products, other caustic chemicals, and petroleum-based products.

Also, if 3% hydrogen peroxide (the only safe home substance that can be used to induce vomiting in dogs) is incorrectly administered, it can enter the lungs and cause significant problems such as pneumonia.

If your dog has a pre-existing health condition or there are other symptoms, inducing vomiting may result in other health risks. If induced vomiting is necessary, having a qualified veterinarian induce vomiting in-clinic is preferable.

When Not to Induce Vomiting

Vomiting should never be induced in a dog that is:

  • Having a seizure or recently had a seizure
  • Lethargic
  • Unresponsive or unconscious
  • Already vomiting

What to Do if You Suspect Your Dog Has Ingested a Toxin

If your pet has ingested a toxin, the best thing you can do is contact your veterinarian and/or poison control right away. This way, our Tucson emergency veterinarians can immediately advise you on whether you should bring your pet in or if you can or should induce vomiting at home.
