Why Is My Dog Panting So Much? Is This Normal?
Most of the time, yes—dogs pant when they’re hot, excited, or coming down from energetic play. But if your dog is panting heavily while resting, or if the panting feels sudden or out of character, it could signal pain, anxiety, overheating, or an underlying medical condition.
Why Is My Dog Panting So Much?
Dogs usually pant to cool themselves down, manage stress, or recover from physical activity—but persistent or heavy panting can indicate a health issue. Here are the most common reasons why dogs pant excessively.
Anxiety or Stress
A dog’s stress response—or fight-or-flight reaction—can trigger panting during anxious moments, says Amanda Farah, CPDT-KA, certified dog trainer and national training coordinator for Best Friends Animal Society in Kanab, Utah.
Stress-related panting looks different than the relaxed panting of a tired, content dog. Watch for body language cues like a tense posture, tight facial muscles, ears pinned back, or wrinkled, V-shaped corners of the mouth.
Pain
Panting that occurs while your dog is resting or in a comfortable environment may be a sign of pain, explains Dr. Garrett Schuilenberg of Small Door Veterinary in New York City. Discomfort can activate a stress response, raising heart and respiratory rates—and leading to noticeable panting.
Heatstroke or Overheating
Dogs don’t sweat like humans do; instead, they rely on rapid breathing—panting—to release heat and regulate body temperature, says Dr. Colleen Lambo, relief veterinarian at Roo in Bryan, Texas. For flat-faced breeds like Bulldogs or Pugs, this cooling mechanism is less efficient, making them especially vulnerable to overheating.
Heart or Lung Disease
Panting while resting or sleeping can sometimes point to heart or lung disease, according to Dr. Katrina Cusack, board-certified veterinary cardiologist at Garden State Veterinary Specialists in Eatontown, New Jersey. Fluid buildup in or around the lungs—or other airway changes—can make breathing more difficult, prompting increased panting.
Hormonal Disorders
Abnormal panting at rest may also signal hormonal imbalances, such as:
- Cushing’s disease
- Hypothyroidism
- Diabetes mellitus
Obesity
Excess body fat can compress the chest and lungs, making breathing more effortful—and causing your dog to pant more often, says Dr. Katja Lang, chief medical officer at Heart of Chelsea in New York City.
When To Worry About Excessive Panting in Dogs
“Panting becomes more concerning when it shows up without a clear reason—like exercise or warm weather—or doesn’t settle once your dog has had time to rest,” says Dr. Lambo.
Call your veterinarian if excessive panting is accompanied by any of these symptoms:
- Lethargy
- Restlessness or pacing
- Whining or trembling
- Drooling or vomiting
- Difficulty standing
- A change in appetite or behavior
Seek emergency care immediately if your dog’s panting comes with any of the following:
- Labored or noisy breathing
- Pale, grayish, or bright red gums
- Coughing
- Weakness or collapse
- Disorientation or confusion
- A rectal temperature over 103°F
What Should I Do If My Dog Is Excessively Panting?
If your dog is panting excessively, start by removing triggers and helping them cool down—but never delay veterinary care if symptoms seem unusual or severe.
Try these expert-recommended steps to keep your dog comfortable:
- Remove triggers and help them settle. Common stressors include guests (people or pets), loud noises, bright lights, or unfamiliar environments.
- Move your dog to a cool, quiet space. Soft sounds or white noise—like those from the FurPetVo Natural Sound Machine—can support calm breathing.
- Offer fresh water and encourage rest. Hydration, rest, and relaxation are essential for recovery.
- Limit activity, especially in warm conditions. Keep things low-key to prevent further overheating.
- Cool them gradually if overheating is suspected. Use shade, air conditioning, or a fan—and consider supportive tools like a FurPetVo Cooling Blanket, FurPetVo Perfect Comfort Cooling Gel Bed, FurPetVo Cooling Vest, or FurPetVo HiDREAM Ice Neck Wrap.
Always contact your veterinarian if your dog’s panting is new, frequent, doesn’t improve with rest, or appears alongside other symptoms—it may indicate pain, illness, or heatstroke requiring prompt attention.
