As our loyal companions age, it’s not uncommon for dog parents to encounter the distressing issue of vomiting in old dogs. While it might be a simple case of a mild stomach upset, in older dogs, it can often signal something more serious. Understanding the causes and knowing when to seek veterinary advice is key to managing your dog’s health effectively.

Vomiting vs. Regurgitation: Know the Difference

Vomiting is the forceful expulsion of stomach contents, involving the contraction of stomach muscles. Regurgitation, on the other hand, is a more passive process where non-digested food comes back up from the esophagus or mouth. Identifying whether your dog is vomiting or regurgitating is crucial as each has different causes and treatments.

Common Causes of Vomiting in Senior Dogs:

  1. Gastrointestinal Issues: This can range from infections, and inflammation, to food intolerances.
  2. Liver and Kidney Diseases: These can lead to toxin buildup, causing nausea and vomiting.
  3. Pancreatitis: An inflamed pancreas, often due to dietary factors, can lead to vomiting.
  4. Neoplasia (Cancer): Tumors in the digestive tract can obstruct food passage, causing vomiting.
  5. Other Factors: Include ingestion of foreign objects, certain medications, heatstroke, or car sickness.

How Often Is It Happening?

Pay close attention to the frequency of vomiting. A single episode may not be alarming, but repeated or chronic vomiting, especially if accompanied by lethargy or other symptoms, should raise concern.

Identifying Dehydration

Dehydration is a serious risk with vomiting. Check your dog’s gums; they should be wet and slippery. Another method is the skin tent test – the skin should snap back immediately when pinched. Lethargy and loss of interest in food or drink are also signs of dehydration.

Age Matters

Age plays a crucial role. For puppies, even a single vomiting episode can be serious. In older dogs, the reasons can be more complex due to their less resilient nature.

When to Call the Vet

Seek immediate veterinary care if:

  • There is blood in the vomit.
  • Your dog attempts to vomit without expelling anything.
  • There are signs of bloating or a swollen abdomen.
  • You suspect ingestion of something toxic.
  • Your dog shows signs of pain, fever, or has pale or yellow gums.

Diagnostic Tests Your Vet May Recommend:

  • Fecal tests
  • Blood tests
  • X-rays
  • Ultrasound
  • Endoscopy
  • Biopsy

Initial Treatment Steps

  1. Withhold food for 24 hours but provide small amounts of water.
  2. Introduce a bland diet like boiled chicken and rice.
  3. Gradually transition back to regular food, as advised by your vet.

Ongoing Management

  • For intestinal worms, administer prescribed dewormers.
  • In case of dehydration, your vet might administer fluids intravenously or subcutaneously.
  • Antibiotics may be necessary if bacterial infection is suspected.

Importance of Accurate Diagnosis

Before administering anti-emetics or other medications, a proper diagnosis is essential. Follow your vet’s recommendations closely.

Quality of Life for Your Senior Dog

While some conditions like kidney or liver disease may require ongoing treatment, you can work with your veterinarian to maintain the highest quality of life for your senior dog.


Understanding what makes an old dog vomit and recognizing when to seek veterinary care are crucial steps in ensuring the well-being of your aging companion. With attentive care and prompt action, you can help your furry friend navigate their golden years with comfort and dignity.
