Dogs that are panting while shaking their jaws can be alarming because these symptoms may indicate a medical condition.
While panting is a normal cooling mechanism, jaw trembling alongside rapid breathing is usually not typical behavior and should be closely monitored.
We outline the common causes of panting and jaw shaking in dogs, what you can do at home, and when to seek veterinary help.

Dog Panting and Jaw Shaking — Why It Happens
Dog panting with jaw shaking often points to stress, pain, or an underlying medical issue affecting the mouth or nervous system. It can occur when a dog experiences dental pain, oral irritation, nausea, or neurological tremors.
Sometimes, anxiety or chills can trigger this involuntary jaw movement, especially if accompanied by rapid breathing or tension.
Panting may also indicate that the dog is trying to cool down or cope with discomfort. While mild, occasional jaw trembling can be harmless, frequent or persistent episodes require veterinary attention to rule out oral infections, seizures, or systemic illness.
Dog Panting and Jaw Shaking: Common Causes
Pain or Discomfort
Panting accompanied by jaw shaking often signals pain. Dogs may shiver or tremble their jaws when experiencing internal discomfort, oral pain, or injury.
Other signs include reluctance to eat, whining, or unusual body posture. Identifying pain early is essential to prevent escalation and to ensure your dog receives proper care.

Anxiety or Stress
Anxious dogs may pant and shake their jaws simultaneously. Stressful situations, like thunderstorms, car rides, vet visits, or separation, can trigger trembling alongside heavy panting.
Watch for accompanying signs like pacing, whining, drooling, or attempts to hide. Providing a calm environment and reassurance can help alleviate mild stress-related symptoms.
Dental or Oral Issues
Oral health problems, including tooth decay, gum disease, or infections, can cause jaw shaking and panting.
Pain or discomfort in the mouth can make it difficult for a dog to close its mouth or eat comfortably.
Other indicators may include bad breath, bleeding gums, or difficulty chewing. Regular dental care and prompt veterinary attention for dental issues are vital for overall health.
Fever or Illness
Illness or fever can cause dogs to pant and exhibit tremors in the jaw. Infections, inflammatory conditions, or systemic illnesses may lead to shaking and rapid breathing as the body attempts to regulate temperature and stress.
Additional signs can include lethargy, vomiting, diarrhea, or changes in appetite. Veterinary evaluation is necessary to diagnose the underlying illness.
Neurological Disorders
Neurological conditions may cause involuntary jaw trembling and panting. Disorders affecting the nervous system, such as seizures, nerve damage, or brain inflammation, can manifest as jaw shaking, muscle tremors, or rapid breathing.
Observe for other neurological signs such as disorientation, imbalance, or abnormal eye movements. Early veterinary intervention is crucial for proper diagnosis and treatment.
Poisoning or Toxins
Exposure to toxins can result in panting and jaw tremors. Ingesting poisonous substances, such as certain plants, human medications, or household chemicals, can affect the nervous system and cause trembling.
Other symptoms may include drooling, vomiting, diarrhea, or lethargy. Immediate veterinary care is essential to prevent severe complications or fatal outcomes.
What to Do If Your Dog Is Panting and Jaw Shaking
Ensure your dog is in a safe, comfortable space away from stressors. Provide fresh water and allow them to rest without disturbance.
Monitor the frequency and severity of the panting and jaw shaking. Keep a record of when the symptoms occur, how long they last, and any triggers.
Gently examine your dog’s mouth for obvious dental issues or injuries. Avoid forcing your dog’s mouth open, as this could cause pain or stress.
Offer calm reassurance and minimize environmental stress. Speak softly, pet gently, and maintain a quiet environment to reduce anxiety-induced panting or trembling.
Assess your dog’s overall health by observing appetite, energy levels, bowel movements, and signs of discomfort. Share this information with your veterinarian to aid in diagnosis.
When to Call or Visit Your Vet
Seek veterinary attention immediately if you notice:
Persistent or worsening panting and jaw shaking without obvious cause
Signs of severe pain, including vocalization, restlessness, or reluctance to move
Difficulty eating, drinking, or swallowing
Vomiting, diarrhea, or other signs of systemic illness
Seizures, disorientation, or abnormal behavior
Suspected ingestion of toxins or poisonous substances
