Why Is My Puppy Throwing Up?Why Is My Puppy Throwing Up?


It can be scary when your puppy starts vomiting. You immediately worry, “why does my puppy keep throwing up?” While it’s normal for puppies to occasionally vomit, ongoing vomiting could signal an underlying health issue.

In this article, we’ll cover the most common reasons puppies vomit and when to see the vet. We’ll also give tips for caring for a vomiting puppy at home.


Common Causes of Puppy Vomiting

Puppy vomiting can occur for many reasons. Here are some of the most frequent causes:

Dietary indiscretion

Puppies are prone to eating things they shouldn’t. Ingesting non-food items, rotting debris in the yard, or rapid food changes can irritate the digestive tract and cause vomiting.


Intestinal parasites like roundworms, hookworms, coccidia or giardia can infect puppies and cause vomiting, diarrhea, or gas.

Viral or bacterial infection

Viral infections like parvovirus or distemper can cause severe vomiting. Bacteria like salmonella or clostridium may also be culprits.

Car sickness

Motion sickness while riding in the car can trigger vomiting in puppies prone to it. An empty stomach and anxiety worsen it.


Eating too much food too fast is a common cause of vomiting in puppies. Their eyes are often bigger than their bellies!

Allergies or food intolerance

An adverse reaction to ingredients in food or treats may cause gastrointestinal upset and vomiting in some puppies.

Blockage or foreign object

Ingesting toys, rocks, sticks or other items can obstruct the intestinal tract and cause vomiting.

Medication reaction

Certain medications, like dewormers, may initially cause vomiting or nausea as a side effect.

When to See the Vet for Puppy Vomiting

If your puppy has vomited once but seems otherwise normal, home monitoring may be okay. But contact your vet promptly if:

  • Vomiting is persistent or projectile
  • Puppy seems lethargic, has diarrhea, or won’t eat
  • Vomit contains blood or a strange color/smell
  • Puppy’s abdomen is tender or distended
  • Vomiting lasts over 24 hours
  • Puppy has a high fever
  • Dehydration occurs (dry gums, sunken eyes)
  • Vomiting is combined with other severe symptoms

Puppies can deteriorate quickly, so when in doubt, call your vet. Severe vomiting or vomiting along with concerning symptoms warrants an exam.

Caring for a Vomiting Puppy at Home

If your puppy has mild vomiting, here are some tips for caring for them at home:

Withhold food – Rest the stomach by taking away food and treats for 6-12 hours. Offer small sips of water.

Avoid medications – Don’t give any OTC meds unless specifically recommended by your vet.

Offer bland diet – After fasting, try serving boiled chicken and rice in small amounts 3-4 times daily.

Prevent dehydration – If vomiting continues, use an oral rehydration solution to replenish fluids.

Watch for improvement – The bland diet and rest should help vomiting resolve within 12-24 hours. If not, call your vet.

Clean up messes – Use an enzymatic cleaner to fully remove traces of vomit and prevent reingestion.

Document episodes – Note time, description of vomit, and events prior to help your vet.

With a little TLC and vet guidance, puppy vomiting often resolves on its own. But severe, recurring cases will need medical treatment.


When to Switch From Puppy Food to Adult Food

Seeing your puppy vomit can be alarming. While occasional vomiting is normal, ongoing episodes could mean an underlying problem. Contact your vet if vomiting persists, contains blood, or is accompanied by other concerning symptoms. They can determine if your puppy needs supportive care or specific treatment. With prompt attention, your puppy will likely be back to their playful selves in no time!
