Dog Vomiting


When a dog throws up —whether it’s acute vomiting or a one time occurrence— it can understandably make dog owners feel concerned, even if the cause is not life-threatening. And because the causes for vomiting can range from everyday occurrences like food intolerance and motion sickness to more serious reasons like underlying issues with your dog’s health, you should know when it requires medical attention, as well as how to help them and what not to do.

Is your dog vomiting?

First, it’s important to establish whether your dog is or isn’t vomiting. Regurgitating and vomiting are two different physiological processes that often look the same to people when it comes to their dogs.

When a dog regurgitates, they passively expel food from their esophagus —meaning food that didn’t go all the way down to their stomachs and therefore has not been digested. When they vomit, on the other hand, they are actively and forcefully ejecting stomach contents. Once you’re sure your dog vomited or has a vomiting bout, it’s important to identify the cause.

Why is your dog vomiting?

For dog parents, it can be alarming whenever their furry kids show signs of being sick. And since vomiting is a common symptom of many illnesses and health issues, it can cause owners to panic.

However, dog vomiting can just be a sign that they ate something they weren’t supposed to, caught a bug from another dog at the park, or that a car ride didn’t sit quite well with them. And if your dog is otherwise healthy, you shouldn’t jump to conclusions and land at the worst possible scenario, as owners often do.

Below are just some of the most common causes for dog vomiting, which range from mild and easily treatable to serious and life-threatening conditions.

Common causes for dog vomitin

Serious causes for dog vomitin

Motion sickness

Diet changes (switching to a new dog food can cause them to have an upset stomach or food allergies, which could result in vomiting. 

Dietary indiscretions (feeding them something they shouldn't eat)

Intestinal parasites

Viral infections (parvovirus, distemper etc.)

Bacterial infections

Ingesting foreign objects

Early signs of heatstroke

Gastrointestinal issues (inflammatory bowel disease, inflammation of the stomach, ulcers, etc.) 

Intestinal obstructions or blockages

Liver disease


Kidney failure 


The cause of your dog’s vomiting will be best identified by a licensed veterinarian, as they will perform different tests (x-rays, biopsies, blood tests, etc) to diagnose and properly treat them. However, if you want to help alleviate your dog or know if they can wait to visit the vet or if you have to take them to the ER, there are signs you can look for, starting with how your dog’s vomit looks.

Some veterinary clinics and veterinarians have designed vomit color charts that owners can use as a reference when they don’t know exactly what they’re looking for. As a rule of thumb, blood in vomit and in any bodily fluid is cause for concern.

When should you take your dog to the vet?

There are certain things that can tip you off when your dog’s vomiting warrants a visit to the vet. If your dog vomits and exhibits other symptoms not associated with the vomiting, they will probably need a veterinarian to treat them. These could be indicative of something like a mild and treatable infection or a more concerning condition. Some symptoms and behaviors you should watch out for include:

Chronic vomiting

Weight loss

Loss of appetite

Irregular urination
