Reasons Why Your Dog Is Not Eating But Drinking Water and Vomiting
If your dog is not eating but drinking water and vomiting, it could be caused by a variety of different issues. He may have a gastrointestinal problem, he may have an infection, or he may have a blockage.
In any case, it is important to get the problem checked out as soon as possible.
- Gastrointestinal Issue
If your dog is not eating but drinking water and vomiting, it could be experiencing a gastrointestinal issue. The symptoms of this condition can be serious, and it is important to get your pet to a veterinarian right away. The main symptoms of gastroenteritis in dogs are vomiting and diarrhea. They usually occur after a dog has eaten something that is difficult to digest.
A dog may also experience unexplained weight loss. You need to take your dog to a vet if they experience this problem. During your dog’s treatment, your vet may recommend a bland or prescription diet.
- Intestinal Blockage
If you notice that your dog is drinking water and vomiting, it is a sign that he or she has an intestinal obstruction. There are a number of reasons for this. The cause can be an overgrowth of the stomach lining, a tumor, or a foreign object.
It is very important to get your dog seen by a veterinarian as soon as possible. Your veterinarian will run diagnostic tests to find the cause. This includes blood, urine, and x-rays. In some cases, an abdominal ultrasound may be required. Symptoms of a gastrointestinal blockage include an increase in abdominal pain, unexplained weight loss, or vomiting.

- Parasites
If your dog is not eating and drinking water and is vomiting regularly, it is possible that it has parasites. These parasites can affect your dog’s health and may require medication and treatment from a veterinarian.
The most common type of worm in dogs is a roundworm. Roundworms can live in the intestines of your dog and cause diarrhea. They can also affect the respiratory system. In severe cases, these parasites can make your dog cough. When they move to the lungs, they can also cause pneumonia.
- Foreign Body Obstruction
If your dog is not eating but drinking water and vomiting due to a foreign body obstruction, there are some steps you can take to help improve his condition. It’s important to note that there are several factors at play here.
The good news is that most dogs recover from a blockage on their own, with or without surgery. An endoscope can be used to look inside your dog’s stomach to find the source of the obstruction.
- Bloat
Bloat is a serious medical condition that can be life-threatening to your dog. It can cause severe damage to the stomach and other organs. The symptoms are usually unseen, but it’s important to treat them as soon as possible.
The most common symptom of bloat is a distended stomach, loss of appetite, and vomiting. Dogs with bloat are often given large amounts of intravenous fluids. These fluids help circulate blood to vital organs. A veterinarian will also give your pet medicine to speed up gastric motility.
- Gastroenteritis
Gastroenteritis is a common condition in dogs. It is usually accompanied by diarrhea, vomiting, and abdominal pain. But it can also be a symptom of a more serious illness.
If your dog is exhibiting these symptoms, it is important to take it to a veterinarian immediately. They will then perform a physical examination to rule out other more serious conditions. Depending on the condition, your vet may recommend intravenous fluid therapy.
Home Remedies for Dogs Not Eating but Drinking Water and Throwing Up
If your dog isn’t eating but drinking water, there are several home remedies for this condition that you can try.
- Pepto-Bismol
Pepto-Bismol is an antacid that works by coating the stomach lining. It can help with nausea, upset stomach, and diarrhea. However, it should not be given to puppies. This is because it can cause gastric ulcer disease. You should only give your dog Pepto-Bismol if he needs it.
- Electrolytes
If your dog doesn’t eat but drinks water and throws up, she probably has a dehydration problem. Dehydration is a serious health condition that can result in death if left untreated. To treat a dehydrated dog, you can give your pet water or an electrolyte solution.
- Probiotics
Dogs suffering from loss of appetite, vomiting, or an upset stomach may need to take dog probiotics to help improve digestion. This can reduce the amount of time that your pet will have the problem and increase the effectiveness of its immune system.
- Slippery Elm Bark
If your dog isn’t eating and drinking, and throwing up, there are several home remedies you can use. One of them is slippery elm bark. It’s a safe, natural remedy that can help ease many of your dog’s digestive problems.
