Vomiting in Dogs

While there can be many reasons why your pup experiences an upset stomach, some are more serious than others. Today, our Fairhaven vets talk about vomiting in dogs, why your dog is throwing up, and what you can do to help.

Why is my dog vomiting all of a sudden?

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

Almost every dog owner understands that while vomiting in dogs is an unpleasant thing to witness and can be distressing it is your pet’s way of emptying their stomach of indigestible material to prevent it from remaining in their system, or from reaching other areas of their body.

Causes of Vomiting in Dogs

Several things can cause a dog to vomit, and sometimes even healthy dogs will fall ill for no apparent reason and recover quickly.

It’s possible your pooch could have eaten too quickly, dined on too much grass, or eaten something their stomach simply doesn't agree with. This type of vomiting may be a one-time occurrence and not be accompanied by any other symptoms. So, vomiting in dogs isn't always a reason 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 failure
  • Liver failure
  • Pancreatitis
  • Change in diet

When is vomiting in dogs a veterinary emergency?

Most dogs will vomit on occasion. If your dog vomits once or even twice, shows no other symptoms, and then returns to normal, there is likely nothing to worry about. (Although we still recommend calling your vet to let them know).

That said, in some cases, vomiting can be a clear indication of a serious medical issue that needs urgent care. Contact your vet right away if you see any of these signs:

  • 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/dry heaving with nothing coming up
  • Vomiting blood
  • Chronic vomiting
  • Continuous, repeated, or recurring vomiting
  • Vomiting accompanied by bloody diarrhea
  • Seizures
  • If vomit appears foamy, or bright green (See below for details)

Chronic Vomiting in Dogs

If your dog has been vomiting frequently or it has become a long-term or chronic issue, this is cause for concern, especially if you’ve noticed symptoms including 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 does the appearance of your dog's vomit indicate?

Depending on the cause, your dog's vomit could be clear, yellow, green, red, or brown and the consistency could be anywhere from foamy or watery to semi-solid. So what do all those characteristics mean? 

That said, here is what some types of vomit indicate in dogs:

  • Bright green or team vomit could mean that your pup has ingested rodent poison. Immediate veterinary care is essential! Contact our emergency vets right away or for further advice call the ASPCA poison control hotline at 1-888-426-4435.
  • Black or brown vomit that looks a bit like coffee grounds can indicate poisoning (this is a medical emergency), ulcers, intestinal blockage, viral conditions, tick-borne diseases, or cancer.
  • Bright red vomit can be a sign of gastritis, ulcers, Inflammatory bowel disease (IBD), foreign body ingestion (contact your vet immediately), trauma (injured stomach, hit by car), clotting issues, heat stroke, parvovirus, or inflammation of the stomach.
  • Light brown could mean that your dog has ingested chocolate (emergency care is required), swallowed mud or dirt, has an intestinal blockage, or has been eating poop.
  • Foamy or white vomit can be a sign of bloat or GDV (contact an emergency vet immediately)

If you are taking your dog to the vet due to vomiting take a sample of the vomit with you for your veterinarian to examine. Why this may seem yucky it can save time (and maybe even your dog's life) when determining the cause of your dog's vomiting.

What To Do If You Suspect Your Dog Has Ingested a Toxin

The best thing to do if you are concerned about excessive vomiting (and diarrhea) in dogs, or if you suspect that your dog has ingested a toxic substance, is to immediately contact your veterinarian or emergency vet, or call the ASPCA Animal Poison Control Center for more advice. 

Do not induce vomiting in dogs unless under the specific guidance of a veterinarian.

How to Settle Your Dog's Stomach When It's Not an Emergency

If you believe that your dog's vomiting is not caused by anything serious there are a couple of things you may want to do to help ease your pup's upset tummy. Of course, we recommend that you still call your vet to let them know what's happening, your vet knows your dog best and could offer suggestions on how best to handle your dog's tummy troubles. That said, many vets recommend the following approaches for mild gastric upset in dogs.

  • Skip your dog's next meal then provide a smaller portion for the following meal. If your dog does not vomit again return to normal feeding.
  • Provide your dog with a light on-the-stomach GI formula dog food from your vet's office to help ease them back to normal eating.
  • Make your dog a light meal of cooked chicken and boiled rice and feed in small portions.
  • Provide your dog with plenty of fresh water to stay hydrated.  
  • If your dog is not back to normal within 24 hours call your vet to book an examination for your pup.
