Why is My Dog Nauseous?

Just like humans, our canine friends too can suffer from bouts of nausea, leading to discomfort and often, a loss of appetite. Understanding what could be causing your dog’s upset stomach can help you seek the right treatment and provide much-needed relief for your furry friend.

Causes of Nausea in Dogs

Many factors can contribute to nausea in dogs. These range from simple overeating or eating something disagreeable, to more serious health concerns, such as gastrointestinal diseases, liver disease, or even cancer.

  • Dietary Indiscretion: Dogs are known for their voracious appetites and curious nature. Unfortunately, this also means they often ingest things they shouldn’t, such as garbage or spoiled food, foreign objects, toxic plants, or even chemical substances. Any of these can cause nausea.
  • New Foods or Treats: Sometimes, a sudden diet change or introducing new treats without a transition period can upset a dog’s stomach, leading to nausea.
  • Motion Sickness: Dogs may suffer from motion sickness during car rides or other forms of travel. Just like humans, the movement can overwhelms their sense of balance and result in feeling nauseated.
  • Parasites or Viruses: Dogs that have worms or have contracted viral infections, such as Parvovirus, may frequently vomit or show signs of nausea.
  • Serious Health Conditions: Chronic diseases like kidney or liver failure, infections, ulcers, or pancreatitis can also cause recurring feelings of nausea.

Signs of Nausea in Dogs

So, why is my dog nauseous and what are signs of nausea in dogs? Identifying nausea in dogs can be tricky as they can’t verbally communicate their discomfort. However, some typical signs can hint at an uneasy tummy. These may include excessive salivation, swallowing excessively, lip-smacking, drooling, vomiting, lack of energy, loss of appetite, and behavioral changes. If your dog exhibits these symptoms, particularly prolonged vomiting and lethargy, you should seek immediate veterinary care.

Prevention and Treatment

Depending on the cause, the treatment may involve dietary changes, administering medication, or more serious interventions like surgery (in cases of ingested foreign objects).

For mild cases, fasting your dog for 12 to 24 hours (under supervision of a vet) can help their stomach settle. Providing a bland diet, including boiled chicken and rice, can soothe their tummy and ease symptoms.

Prevention is often the best medicine. Regular de-worming, feeding a consistent, balanced diet, and avoiding table scraps can help keep your dog’s stomach in top shape. Additionally, minimize their access to non-food items that they might ingest out of curiosity.

Lastly, remember that persistent or severe symptoms of nausea warrant a visit to your veterinarian. With their expertise, they can diagnose the underlying cause and provide appropriate treatment options, ensuring your furry friend’s quick recovery and continued health.


In summary, dogs can get nauseous due to various reasons ranging from a simple upset stomach to complex health conditions. It is critical to understand these reasons and monitor the symptoms to provide your dog with the best possible care.
