Why Is My Puppy Throwing Up?

Vomiting is a common symptom of many illnesses, but most often it means something else is wrong. Make sure to check your pet’s mouth and nose for anything unusual, such as blood or mucus. Also, be aware that some medications may cause your dog to vomit. Your vet might want to examine him thoroughly first to make sure there isn’t something else going on.

Vomiting is a protective response intended to protect your dog from poisoning. It’s triggered by a special part of the brain called the CTX. Vomiting is completely different than being ill. Your puppy is throwing up because he’s feeling poorly. He might also be showing signs of pain.

While vomiting may be a sign of a serious illness, it also indicates other things such as diarrhea, constipation, or even indigestion. For example, if your dog vomits after eating, he could be experiencing indigestion. 


Knowing what caused your dog’s vomiting is vital to finding the right treatment.

Heatstroke occurs when your dog overheats and loses water. 

Intestinal parasites can also be the cause of vomiting. Some common types include Giardia coccidia roundworms, whipworms, and tapeworms.

Dogs suffering from gastritis or gastroenteritis should receive supportive care by administering fluids and electrolytes intravenously. Antibiotics are also commonly used to treat infections caused by bacteria.

Gastrointestinal obstructions happen when you swallow something sharp or get your hands on some other object that gets lodged in your throat. You can also suffer from hemorrhagic gastroenteritis, which causes sudden, severe bleeding in your digestive system. Finally, there are ulcers, which occur when your stomach acids erode away at the lining of your esophagus and stomach.

Pancreatitis happens when your dog’s pancreas gets inflamed. This causes him to lose his appetite and produce too much digestive juice.

Most commonly, the cause is “dietary indiscretions” – eating something nasty!

Yellow, White, or Brown Vomit: What The Different Colors Mean? 

Vomiting occurs when something goes wrong with the digestive system. Food can get stuck in the stomach or intestines, causing nausea, vomiting, diarrhea, abdominal pain, headache, dizziness, weakness, fatigue, fever, chills, sweating, confusion, loss of appetite, and even shock.

Vomiting is a very active process that causes muscles to contract and the entire body to tense. When dogs vomit, you’ll often see food coming out of the mouth or nose, along with bile or other fluids from the digestive tract.

Yellow vomit indicates that your puppy has ingested something toxic. Call your vet if there is concern about the color. White or foamy vomit may indicate irritation or illness.

Your dog may be sick if he vomits dark brown or black substances.

The blood may come out of any organ in the body, but most often from the stomach, esophagus, or upper intestines. If you notice blood in your dog’s bodily fluids, you should take your dog to see your veterinarian as soon as possible.

What You Can Do

With regard to vomiting, there’s a lot more going on than simply having something “wrong” with your dog. Vomiting can be caused by a variety of things including food sensitivity, parasites, intestinal worms, or even cancer.

A dog that throws up isn’t necessarily ill or in need of immediate veterinary care. Feeding a bland diet and/or anti-nausea medications can help control symptoms. Serious conditions often require more intensive treatment, including hospitalization, intravenous fluids, and sometimes surgery.

Fluid therapy may be required if the vomiting is due to dehydration.

To help ease your pet’s discomfort, give them nothing but water for 24 hours. After that, continue to feed them regular meals and make sure to clean out their feces regularly.

Your dog may be having problems digesting a particular food. To figure out what’s wrong, start by eliminating all other foods from their diet. Then, take note of any vomiting or diarrhea.

Dogs with chronic vomiting may need more help than home care alone can provide. Consult your vet about the best ways to address your dog’s problem. If the vet rules out underlying causes, treatment can be as easy as a diet change. Home-cooked meals can help dogs feel better during times of illness.

When Should You Call Your Vet?

If your dog vomits repeatedly without producing anything else, contact your vet immediately. A clinical examination checks your dog over by examining him/her and asking questions. Blood tests, urine tests, X-rays, or an ultrasound may be performed to help diagnose any problems. Treatment will depend on what is causing the problem. Surgery may be needed to remove anything lodged inside the intestines.


Puppies should be fed small meals frequently throughout the day. If you’re worried about your dog eating too much, start with smaller portions than usual, and work your way up as needed.

Dogs should never eat things they aren’t supposed to eat. Chocolate, macadamia nuts, and onions are among the foods that dogs should avoid.

Also, try to avoid giving him any treats or foods that contain caffeine. Be sure to read labels carefully before making any changes to your dog’s diet. You may want to consult your veterinarian about what types of diets are most suitable for your dog.

Your dog may have other underlying issues related to anxiety that could be causing him to throw up after eating. You can help him by showing him how much you care about him and continuing to give him lots of attention and affection. 

Dogs sometimes regurgitate after meals for no apparent reason. If you suspect your dog might be suffering from gastric reflux or other health issues, call your veterinarian immediately. Once the vet knows more about your dog, he’ll decide how to proceed. He’ll probably want to take a sample of your dog’s feces to check if there are any parasites or worms. Sometimes he’ll need to perform a physical exam.
