How to Tell if Your Dog is Nauseous

Nausea in dogs can be a distressing experience for both pets and their owners. Just like in humans, dogs can feel nauseous due to various reasons, such as consuming something toxic, gastrointestinal issues, or even being car sick. As a responsible pet owner, it is crucial that you recognize the signs of nausea in your dog to provide them with proper care and prevent potentially serious health conditions. If you’re wondering “how to tell if my dog is nauseous?”, here are some of the most common symptoms you should look out for.

Vomiting and Regurgitation

One of the most apparent indicators of nausea in dogs is vomiting or regurgitation. Vomiting involves the forceful ejection of stomach contents through the mouth, while regurgitation is more of a passive release of undigested food from the esophagus. If your dog has been vomiting frequently and showing signs of discomfort, it might be an indication of nausea. Keep in mind that occasional vomiting may not always be a cause for concern, but frequent vomiting warrants a visit to the vet to determine the underlying cause.

Lethargy and Weakness

When a dog is nauseous, they may become lethargic or weak due to a lack of appetite, dehydration, or discomfort. Suppose you notice that your dog is much more tired than usual and exhibits a general lack of interest in their usual activities. In that case, it could be a sign that they’re experiencing nausea.

Excessive Salivation

Nausea can cause excessive salivation in dogs, leading to drooling. If you notice an unusual amount of drooling accompanied by other symptoms such as vomiting or loss of appetite, it could be a sign of nausea.

Loss of Appetite

A nauseous dog may show a decreased appetite or even an inability to keep food down. If your dog is refusing to eat, especially if they’re usually very enthusiastic about their meals, it’s essential to monitor them for signs of nausea and consult your veterinarian.

Lip-smacking or Gagging

Dogs experiencing nausea may try to alleviate their discomfort by lip-smacking, swallowing repeatedly, or gagging. If you observe your dog engaging in these behaviors, particularly in conjunction with other symptoms, it could be a sign of nausea.

Whining and Restlessness

Nausea can cause discomfort in dogs, resulting in whining, pacing, or restlessness. Pay attention to your dog’s body language and vocal cues to determine whether they’re experiencing nausea.

Unusual Body Postures

A nauseous dog may exhibit specific body postures, such as an elongated neck or hunched back, or stand with their head hanging low. These positions might help your dog feel more comfortable while combating their nausea but can also be a sign that they’re not feeling well.

What to Do If Your Dog is Nauseous

If you suspect that your dog is experiencing nausea, it’s essential to visit the veterinarian as soon as possible to determine the underlying cause. The vet may recommend a specific treatment plan depending on the cause of your dog’s nausea, such as dietary changes, medication, or even hospitalization for severe cases.

In the meantime, you can help your nauseous dog by providing a quiet and comfortable environment to rest. Keep your dog hydrated by offering them small amounts of water and avoiding any food until they have stopped vomiting.


Recognizing the signs of nausea in your dog is vital for their well-being and health. Paying close attention to their behavior, appearance, and appetite will help you determine whether they’re experiencing nausea or other health issues. Always consult with your veterinarian for professional advice and treatment if you suspect your dog is nauseous.
