Dog Sneezing and Shaking: Causes and When to See a Vet
If your dog is sneezing and shaking at the same time, it can be unsettling. These two signs together may point to several different causes, ranging from mild allergies to conditions that need prompt veterinary attention.

Quick Answer
Sneezing paired with shaking can be caused by a fever, an allergic reaction, a nasal foreign body, anxiety, or exposure to a toxin. Many causes are treatable, but some require prompt veterinary care. Monitor your dog closely for additional signs such as lethargy, swelling, or difficulty breathing, and contact a veterinarian if the combination persists or worsens.

Common Causes of Sneezing and Shaking Together
Several different issues can produce both sneezing and trembling in a dog. The combination is worth noting because it narrows the list of possible explanations compared to either sign alone.
Fever
A fever can cause dogs to shake or tremble as their body temperature rises. If an infection is also affecting the nasal passages, sneezing may occur at the same time. Respiratory infections, such as kennel cough or canine influenza, are sometimes associated with both signs.
Signs that fever may be involved include:
- Warm ears and paws
- Lethargy or reluctance to move
- Reduced appetite
- A warm, dry nose (though this is not a reliable indicator on its own)
A rectal temperature above 102.5 degrees Fahrenheit (39.2 degrees Celsius) is generally considered elevated in dogs. If you suspect a fever, a veterinary examination can confirm it and help identify the underlying cause.
Allergic Reaction
Environmental allergens such as pollen, dust mites, or mold spores can irritate a dog's nasal passages, leading to repeated sneezing. In some cases, the irritation or discomfort may also cause the dog to shake, particularly if the reaction is widespread.
Allergic reactions may also cause:
- Itchy skin or paw chewing
- Red, watery eyes
- Rubbing the face on surfaces
- Redness or swelling around the muzzle
Mild seasonal allergies are common and often manageable, but sudden or severe reactions should be evaluated by a veterinarian.
Nasal Foreign Body
A grass awn, seed, or small object lodged in the nasal passage can cause persistent, forceful sneezing. The discomfort from a foreign body may also lead to head shaking or generalized trembling.
Signs of a nasal foreign body include:
- Sneezing that is sudden in onset and persistent
- Pawing at the nose or face
- Nasal discharge from one nostril, which may contain blood
- Head tilting or rubbing the nose on the ground
A foreign body typically requires veterinary removal. Attempting to extract it at home can push the object deeper or cause injury.
Anxiety or Stress
Stress and anxiety can produce physical signs in dogs, including trembling or shaking. If a stressful event coincides with environmental irritants, a dog may sneeze and shake simultaneously.
Common stress triggers include:
- Loud noises such as fireworks or thunder
- Changes in routine or environment
- Visits to unfamiliar locations
- Separation from owners
If anxiety appears to be the primary cause, the sneezing is usually mild and resolves once the stressor is removed. However, persistent anxiety may benefit from a behavior-focused discussion with a veterinarian.
Toxin Exposure
Exposure to certain toxins, such as some household chemicals, plants, or medications, can produce a range of signs including sneezing, trembling, and in more serious cases, seizures or collapse.
Additional signs of toxin exposure may include:
- Excessive drooling
- Vomiting or diarrhea
- Confusion or disorientation
- Pale gums
If toxin exposure is suspected, contact a veterinarian or a pet poison control service immediately. Time can be a critical factor.
When to Contact a Veterinarian
Some situations involving sneezing and shaking require urgent veterinary attention, while others can be monitored briefly at home.
Contact a veterinarian promptly or seek emergency care if you observe:
- Difficulty breathing, open-mouth breathing, or noisy breathing
- Swelling around the face, muzzle, or throat
- Pale, blue, or very dark gums
- Collapse, inability to stand, or severe lethargy
- Known or suspected toxin exposure
- Sneezing that produces blood
- Seizures or severe tremors
Schedule a veterinary appointment if:
- The sneezing and shaking persist for more than 24 hours without improvement
- Your dog appears uncomfortable but is otherwise alert and eating
- There is mild nasal discharge without other emergency signs
- You notice a gradual onset of signs over several days
At-home monitoring may be appropriate for a short period if:
- Your dog is alert, eating normally, and behaving typically otherwise
- The signs are mild and intermittent
- There are no additional signs of illness
Keep a brief log of when the sneezing and shaking occur, what your dog was doing at the time, and any other signs you notice. This information can be helpful during a veterinary visit.
Frequently Asked Questions
Can allergies cause a dog to shake?
Yes. Allergic reactions can cause generalized discomfort or itchiness that leads to shaking or trembling. If the allergen also irritates the nasal passages, sneezing may occur at the same time.
Should I take my dog to the vet if they are sneezing and shaking?
It depends on the severity and duration of the signs. If the combination is mild, brief, and your dog is otherwise acting normally, a short period of at-home monitoring may be reasonable. If the signs persist beyond 24 hours, worsen, or are accompanied by emergency indicators such as difficulty breathing, contact a veterinarian promptly.
Can a nasal foreign body cause trembling?
Yes. The discomfort of a foreign object in the nasal passage can be significant, and some dogs may tremble or shake their head in response. Pawing at the nose and one-sided nasal discharge are common accompanying signs.
How can I tell if my dog has a fever?
The most reliable method is taking a rectal temperature with a digital thermometer. A temperature above 102.5 degrees Fahrenheit (39.2 degrees Celsius) is considered elevated. Warm ears or paws alone are not a dependable indicator.
