Your dog keeps throwing up.  Find out why and how you can help them.

There are many reasons why your dog vomits. For instance, to push out something he should not have swallowed in his stomach.

However, there could be cases where vomiting indicates a serious medical issue. Keep reading to find out why your dog keeps throwing up and how you can help them.

Vomiting vs. Regurgitation

First and foremost, it is vital to differentiate between regurgitation and vomiting. Regurgitation occurs inertly, with foods that are not digested properly, and they come up out of his esophagus without abdominal effort.

Normally, it is an indication of an esophageal issue. Regurgitation should be distinguished from throwing up as the cause and cure for the two cases are different.

Throwing up or vomiting is normally preceded by symptoms of nausea such as licking lips, swallowing extremely, and drooling. Some canines might eat grass as a form of protection for the esophagus as the grass can cover sharp objects such as bone shards.

Throwing up is an active process that takes account of abdominal walling contraction.

Reasons Why My Dog is Throwing Up?

Reasons why my dog is throwing up

The ingestion of an irritating object or substance

Throwing up happens if your beloved canine friend ate something he should not have. This can be rotten food, or perhaps a rock or part of a chewed toy, which aggravates the stomach and intestine as it passes through. Sometimes these things can get stuck in the intestine, which can be an alarming issue.

If this happens, his stomach will be sore. Anything he eats or drinks will come out again, such as Natural Dog Treats. This can be life-threatening, and your dog requires surgery to get rid of the obstruction.

Intestinal parasites

Dogs may throw up if he has a heavy burden of roundworms in the small intestine, as they can interfere with food passage. Often the first indication of a viral infection like parvovirus is vomiting and loss of appetite. If your dog is not vaccinated and begins to vomit, and shows symptoms of depression, call your veterinarian quickly.

Contaminated water

If your pup has been drinking out of puddles outdoors or has been partaking in a community drinking bowl, there may be an imbalance in bacteria that can cause stomach upset.

Additionally, dogs should never drink out of a lake because there may be cyanobacterium or blue-green algae. This can be deadly for your dog. Vomiting may be the first sign of a problem, but more severe cases can result in neurological issues and death.


If your dog is bloated, this can also cause them to vomit randomly. Bloat is also known as gastric dilatation and volvulus and is an acute and life-threatening condition that may require that your dog is hospitalized and treated.

When the stomach fills with air, it can twist itself up, cutting off circulation and causing the dog to go into shock. This is more commonly seen in large breed dogs, including German Shepherds, Great Danes, standard poodles, Labrador Retrievers, and Golden Retrievers.


Pancreatitis can be an acute cause of dog vomiting. If your dog has pancreatitis, it should be on an extremely low-fat diet as it can also lead to diabetes.

Inflammatory bowel disease

Inflammatory bowel disease or IBD can lead to chronic vomiting in dogs. It is often associated with other lower GI symptoms, with vomiting being the primary.

Bilious vomiting syndrome

Bilious vomiting syndrome or BVS is a condition where dogs vomit yellow foam (bile) or froth but nothing else. It is often caused by gastric retention and is easily treated. If you notice yellow vomit, give your dog smaller and more frequent meals and an antacid when needed. Bilious vomiting syndrome most often affects younger dogs, but it can happen to them at any age.

Kennel cough

When dogs have kennel cough, they may start vomiting up undigested food, white foam, or phlegm. It can also cause gagging, eye discharge, and a runny nose. If your dog is suffering from kennel cough, they may be sick for one to three weeks, but the symptoms, including dog vomit, can last up to six weeks. Consult with your veterinarian if you notice your dog becoming ill.

Motion sickness

When does your dog vomit? If you notice they vomit when they get into the car, this could simply be due to motion sickness and isn’t something to worry about. If your dog is prone to motion sickness, withhold food for twelve hours, keep the vehicle cool and quiet, and offer your dog ginger. It is safe for dogs in small doses and promotes healthy digestion.

Food allergy

One of the signs of a food allergy in a dog is digestive disturbance or dog vomit and diarrhea. Skin issues related to an allergy may start between 6 and 24 hours after eating the food, but digestive upset may manifest sooner.

Types of dog throw up

Even if it is unpleasant, it is important to take some time to assess your dog’s puke before cleaning it up.

Foamy vomit can signify that your dog is suffering from gastritis or pancreatitis. Blood present in the vomit could be that your canine is bleeding in its gastrointestinal tract.

Green throw-up can indicate that your pet swallowed some form of poison used to kill rats or cockroaches, which is very risky and perilous.

What do you need to do?

Serious and frequent vomiting needs instant treatment. When your pet exhibits any of the signs mentioned below, you need to call a vet.

  • Frequent throwing up: Pets who throw up often can be debilitated. This is true for old dogs or those who have medical issues.
  • Projectile throwing up: Potentially an indication of a thwarted gastrointestinal tract.
  • Depression and lethargy: Signs that your dog’s entire system is adversely affected.
  • Reduced urination: Reduced production of urine is seen with dehydration
  • Chronic diarrhea: A combination of serious vomiting as well as diarrhea can lead to dehydration
  • Abdominal enlargement or pain: these indications are usually seen with serious causes of throwing up in canines.

Throwing up in puppies

Throwing up in puppies

It may be hard for puppies to tolerate the effects of throwing up too frequently. Puppies may instantly become feeble or die from the benign cause of throwing up if they don’t get an instant cure or treatment. When your puppy is vomiting, immediately go to the vet to assess their condition.

What to give to your dog after throwing up

If your dog has just vomited once and is doing fine, vets will recommend various home treatments such as:

  • Remove all sources of water and food for 6 to 8 hours.
  • When your canine friend doesn’t throw up during that period, give him half a glass of water. When he is accustomed to that, slowly reintroduce lots of water.
  • After 12 hours, and your pet has not shown symptoms of throwing up, give him a small amount of food such as boiled chicken meat with rice. Make sure the chicken doesn’t have any skin or bone. Once he eats this without throwing up, augment the meal’s size and begin mixing in his regular meal.

This process will take about three days. If he starts to vomit again, visit the veterinarian immediately.

When is dog vomiting normal?

There are several different causes for a dog randomly throwing up, especially if your dog is vomiting white foam. Knowing and recognizing the symptoms is important to deal with the problem.

Throwing up is not always an indication of serious illness. If your dog vomits once or twice and is subsequently well, it might not be serious. It could mean they ate their meal too fast and the undigested food is coming up, or something they swallowed simply didn’t agree with them.

However, to play it safe, you should observe your dog for approximately the next 12 hours. Avoid feeding them too much for 24 hours. Begin with small frequent meals of bland food such as chicken or boiled white rice.

On the other hand, if your pup has a sudden onset of repeated throwing up that does not resolve, or if your dog is depressed and there’s blood in the throw-up, you need to contact a veterinarian.

Throwing up more than once or twice a week for a long period can result in nutrient deficiencies and energy shortage. This kind of vomiting tends to be related to conditions like food allergies or inflammatory bowel disease.

If you notice any of the following signs and symptoms, it is best to consult with your vet because it could be pointing to a more serious medical problem.

  • Prolonged and continuous vomiting
  • Chronic vomiting
  • A lot of vomit at one time
  • Fever, weight loss, lethargy
  • Bloody vomit
  • Vomiting, but nothing comes up
  • Bloody diarrhea
  • You suspect they swallowed a foreign object
  • Seizures

Chronic vomiting can signify kidney or liver failure and is often accompanied by other signs such as diarrhea and bad breath. Chronic dog vomiting typically presents with blood, abdominal pain, depression, dehydration, weakness, fever, poor appetite, weight loss, and other unusual symptoms.

On the other hand, acute vomiting can mean intestinal obstruction, cancer, parvovirus, colitis, constipation, liver disease or liver failure, kidney failure, systemic illness, intestinal inflammation, pancreatitis, or a uterine infection.
