Seeing your dog shaking and panting can be distressing, especially if the symptoms appear suddenly or without an obvious cause. These behaviors may be signs of pain, anxiety, overheating, or even a serious medical condition.
We outline the common causes of dog shaking and panting, what you can do at home, and when to seek veterinary help.
Dog Shaking and Panting — Why It Happens
Dogs shake and pant when they’re anxious, in pain, overheated, or suffering from illness. Panting helps regulate body temperature, but when combined with trembling, it can signal distress. This combination is common in dogs experiencing fear, fever, or systemic illness.
Common Causes of Dog Shaking and Panting
Anxiety or Stress
Many dogs shake and pant in response to loud noises, separation anxiety, vet visits, or travel.
You might notice dilated pupils, pacing, or clingy behavior. These are signs your dog is overwhelmed or scared.
Calming aids, routine, and desensitization training can help manage anxiety over time.

Pain or Injury
Dogs may tremble and pant if they’re in pain—whether from arthritis, dental problems, abdominal discomfort, or internal injury.
Even if no injury is visible, internal discomfort can cause these symptoms.
Panting is the body’s response to pain, and shaking may indicate the dog is trying to mask or process that pain.
Fever or Infection
An elevated body temperature due to an infection or illness can lead to full-body trembling and excessive panting.
Look for additional signs like reduced appetite, lethargy, or warm ears and paws.
Fever is a symptom of many diseases and should always be investigated by a vet.
Heatstroke or Overheating
If your dog is shaking and panting after exercise or being outside on a warm day, it may be overheated.
Heatstroke is life-threatening. You may also notice drooling, weakness, vomiting, or collapse.
Move your dog to a cool area immediately and seek veterinary care if symptoms don’t quickly improve.
Cushing’s Disease
Cushing’s disease (excess cortisol production) causes chronic panting, muscle weakness, shaking, and increased thirst and urination.
Older dogs are more prone to this condition, and it often develops slowly over time.
Blood tests are required to diagnose Cushing’s, and treatment options vary by case.
What to Do If Your Dog Is Shaking and Panting
Stay calm and observe your dog carefully. Look for signs of injury, heat exposure, or environmental stress.
Move your dog to a quiet, cool place with fresh water available.
Avoid sudden movements or loud sounds that may worsen anxiety.
If symptoms are mild and resolve within an hour, monitor your dog closely for recurrence.
Do not administer human medications unless directed by a vet.
When to Call or Visit Your Vet
Contact your veterinarian if your dog:
Is shaking and panting for more than 30–60 minutes
Shows signs of pain, lameness, or abdominal bloating
Has a fever, vomiting, or diarrhea
Is disoriented, confused, or collapses
Is very old, very young, or has underlying health conditions
These signs could indicate heatstroke, poisoning, or internal issues that need urgent care.
