Why is My Dog Vomiting, and What Can I Give My Dog For Vomiting?

If you’re a dog parent, nothing can get you worked up like your pet getting sick. If they’re vomiting, it’s undoubtedly a cause of concern in our books. However, your dog vomiting is not always a signal to run off to the vet.

While some causes are definitely stressful, others are quite common and easily go away with some at-home interventions. The tricky part is to differentiate between these causes. 

Lucky for you, in this guide, we’ll discuss dog vomiting and diarrhea information while helping you differentiate between the vomit types and the possible ways to deal with the situation. 

What Is the Difference Between Regurgitation and Dog Vomiting?

Since they’re both different things, your reaction to them should vary too. For that, you need to learn the difference between them. 

First off, regurgitation is a passive process in which your dog throws up the undigested food from its esophagus. Basically, this food never went to the stomach. 

Regurgitation commonly occurs soon after eating, in case your dog was eating too quickly or possibly ate too much. If your pet’s abdomen doesn’t heave during throwing up, it’s a sign of regurgitation. 

On the other hand, vomiting refers to the ejection of food from the stomach. Your dog’s vomit may have partially digested dog food or bile. Most often, the material smells sour and has a characteristic color. 

Dogs normally do two things after vomiting. First, they will want to drink a lot of water since vomiting leaves them dehydrated. However, you should keep the water bowl away since more water means more vomiting. 

Second, your dog could eat grass after vomiting to protect the esophagus. Since grass protects the esophagus from bone shards and other sharp materials, dogs may eat it before vomiting too. 

However, you shouldn’t let them eat too much as it could be problematic. 

When Is Vomiting Not A Cause of Concern?

As a dog parent, you should know that dog vomiting isn’t something uncommon. If your dog is sick or has overeaten, they may throw up the food. Plus, dogs tend to vomit if they eat something disagreeable. 

In such cases, you don’t need to worry, as the vomiting will subside once the issue goes away. 

When Should You Be Worried?

You should start dialing the vet’s number if the following happens:

  • Bloody vomit 
  • Chronic vomiting
  • Vomiting accompanied by other symptoms, such as anemia, weight loss, and fever
  • Bloody diarrhea 
  • Seizures 
  • Vomiting excessively at once

Causes Of Acute Vomiting 

Acute vomiting refers to sudden bouts of vomiting and is often a symptom of one of the following health conditions or lifestyle changes:

  • Bacterial infection 
  • Kidney failure
  • Ingestion of toxins of poison  
  • Pancreatitis
  • Viral infection 
  • Ingestion of harmful foods, like chocolate 
  • Heatstroke 
  • Reaction to a medication 
  • Post-operative nausea
  • Intestinal parasites
  • Obstruction by foreign bodies, like toys, in the gastrointestinal tract 
  • Gall bladder inflammation 

If this happens, you should let the vet diagnose the cause of the problem. Since you spend time at home with your pet, you should do your best to fill in the vet with anything unusual that might have happened. 

For instance, if you notice a disruptive mess around your garbage bin, it’s likely that your pet might have eaten something from there.

Or, if your dog started vomiting after being in a hot car for too long, it could be a sign of heatstroke that you must mention to the vet.

Identifying the Color of Dog Vomit 

Your dog’s vomit color can help identify the cause of the problem. Here are some common colors to look out for. 


Bile imparts the yellow coloration to your dog’s vomit, and it’s a sign that the pet’s stomach was empty at the time. The reason, in this case, could be reflux or acid buildup. 


If you’re worried about the dog vomiting white foam, stomach acid could be the culprit. When the vomit is sloshed around in the body or comes in contact with air, it becomes foamy. 


If the vomit resembles mucus or is slimy, it’s possible due to some form of irritation. Your dog is vomiting mucus to ease the nausea they feel due to the irritant. 


A clear vomit could be due to stomach secretions. It means that your dog is feeling nauseous and is having a hard time even keeping water inside. 


A bloody vomit is always a reason for concern and immediate action. If you notice fresh or clotted blood in your dog’s vomit, rush to a vet. The possible reasons for this could be lack of blood clotting, ingestion of rat poison, tumor, or an ulcer. 

When Should You Take Your Dog To A Vet?

Occasional vomiting is not much to worry about as it subsides instantly. However, if your dog vomits more than once a day or has been vomiting constantly for days, talk to a vet immediately. 

Plus, if you notice other symptoms, like weight loss, blood in vomit, or fever, it’s an indication that you need to call the vet as soon as possible. 

Ignoring your dog’s condition could be fatal in some cases too.
