Table of Contents

It’s distressing to see your canine companion vomit up a meal they just ate. While occasional regurgitation may happen simply from overeating or eating too fast, frequent vomiting of undigested food requires veterinary attention to pinpoint the root cause. This article explores all the reasons your dogs throw up food, from minor to serious, as well as steps to help alleviate their upset stomach.

 Main Reasons Dogs Throw Up Food 

If your dog is vomiting food, bile, or parts of meals hours after eating, the most common culprits involve their:
Diet: Eating expired, rancid, or very fatty foods can induce vomiting. Food allergies or intolerances may also be at play.
Eating Habits: Eating too fast, too much, or taking part in intense physical activity after a meal can all increase vomit risk.
Toxin Exposure: Getting into trash, chemicals, or critters like toads and insects can cause nausea and vomiting.
Foreign Objects: Swallowed toys, clothing items, sticks, or non-food objects may obstruct or irritate the gastrointestinal tract.
Parasites: Intestinal worms, giardia, or coccidia parasitic infections often manifest through gastrointestinal upset.
Viruses: Canine parvovirus and other viral conditions frequently involve nausea and vomiting.
Illnesses: Diseases like kidney failure, liver issues, diabetes, cancer and more can spark sustained vomiting.
So while sometimes minor diet or behavior adjustments may help, frequent regurgitation of food warrants veterinary investigation, especially when paired with other symptoms. Never assume it is harmless, even if your dog acts normal otherwise.

 What Does Vomiting Undigested Food Mean?

When a dog throws up largely undigested food more than 12 hours after eating, this points to an obstruction or significant digestive issues slowing passage time. Possible causes include:
– Foreign body obstruction
– Inflammatory bowel disease
– Severe food intolerance
– Gastrointestinal ulceration
– Pyloric outflow disease
– Certain cancers
Quick veterinary care is crucial, as persistent vomiting can lead to dangerous fluid/electrolyte imbalances. Be prepared to provide your vet details like what your dog ate, when symptoms started, and any other relevant history. This aids in prompt, accurate diagnosis and treatment. Don’t hesitate to seek emergency assistance if your dog seems in distress.

 When to Worry About Dog Vomiting


Occasional vomiting generally doesn’t warrant major concern. But seek prompt veterinary care if vomiting is:
– Frequent or recurrent
– Projectile or extremely forceful
– Bloody or a strange color
– Contains foreign items or weird textures
– Accompanied by symptoms like diarrhea, weakness, pain or lethargy
Especially monitor puppies closely, as dehydration from GI issues can become life-threatening quickly. When in doubt, call your vet, as they can advise next steps for care based on your dog’s overall condition.

What To Do If Your Dog Keeps Throwing Up  

If your dog vomits multiple times, bloody material, or undigested food, urgent veterinary assessment is needed. Additionally, at home:
– Withhold all food/treats for 6-12 hours
– Slowly reintroduce water or bone broth if vomiting persists past a few hours
– Avoid any diarrhea medication without veterinary direction
– Note any Dietary indiscretions or toxin exposure
– Collect a fecal and urine sample if gastrointestinal signs
– Monitor energy levels and hydration status closely
Getting to the root cause via testing helps guide treatment so your dog recovers smoothly. In the meantime, small hydration maintenance is key.

Why Do Older Dogs Throw Up Undigested Food?

For senior dogs throwing up meals long after eating, common age-related culprits include:
– Oral health decay leading to nausea
– Decreased stomach emptying rates
– Insufficient digestive enzymes
– Liver or kidney disease
– Idiopathic gastrointestinal hypermotility
– Insulinoma or other hormone issues
– Prescription medication side effects
Seeing undigested kibble or vegetables is especially concerning in elderly dogs. Catching conditions exacerbating elderly vomiting quickly improves comfort. Medications, diet changes, or addressing underlying illnesses help minimize these unpleasant symptoms.

 Treating the Cause of Vomiting

The best way to treat dog vomiting is by addressing the underlying trigger, which may involve:
– Changing to a hypoallergenic dog food
– Worming or antibiotic medication for infections
– IV fluids or antacids for gastrointestinal ulcers
– Imaging tests and surgery for foreign body obstructions
– Chemotherapy medications if due to cancer
– Insulin or steroids for endocrine pancreatic disorders leading to vomiting
While vomiting can sometimes resolve on its own, determining the origin is essential to prevent complications and relapses. Be proactive by partnering with your vet if stomach issues persist despite symptom treatment. Getting to the root cause saves your dog extensive distress.

When Should I Take My Vomiting Dog to The Vet?

Make an appointment with your veterinarian if your dog shows these vomiting red flags:
– Repeated vomiting more than 2 times per week
Lack of appetite exceeding 24 hours
– Significant lethargy or diarrhea alongside vomiting
– Dark-red blood or unrecognizable substances in vomit
– Undigested food particles 12+ hours after eating
– Weight loss or failure to gain weight
– Vomiting and drinking/urinating excessively
– Projectile vomiting or violent stomach convulsions
– Persistence beyond 48 hours without improvement
Triggers like dietary changes or minor illness can spark some vomiting but it should gradually resolve as your dog recovers. Call the vet if nausea and food regurgitation continue or worsen despite home monitoring. Prompt medication and hydration support make all the difference.
