Although panting is normal for dogs on hot days or while playing fetch, excessive panting at night can be concerning. Nighttime panting can be an indication that something is wrong, in addition to causing you and your dog sleepless nights. Our Port Jefferson vets talk about why your dog pants at night, and when to go to the vet.
Panting in Dogs
Panting is a completely normal bodily process for dogs, just like sweating is for humans, and it assists them in regulating their body temperature. Panting in the middle of the night is another story, especially when there is no obvious cause for the dog's distress.
Why is my dog panting so much at night?
There are several situations in which your dog's panting is not cause for concern, such as after a long walk in humid weather, an active play session, or excitement. Panting and restless behavior (for example, pacing) in mild or ideal weather, or at night when it is cooler, may indicate something more serious. Excessive panting could be caused by several factors, including:
- Cushing’s Disease. This is when the bloodstream has a buildup of too much cortisol. Along with panting, other symptoms of Cushing's Disease in dogs include an increase in thirst, increased hunger, frequent urination, hair loss, and a pot-bellied appearance. This issue is commonly seen in senior dogs and is often one of the reasons for abnormal heavy panting.
- Respiratory disease. Respiratory problems make it difficult for your dog to breathe, making it difficult for them to get the oxygen their bloodstream needs to carry throughout their body. Even light exercise can cause a dog with respiratory problems to pant heavily or struggle to breathe. If your dog's tongue is no longer a healthy pink but instead blue, purple, or grey, take him to the vet right away for treatment; he may be suffering from oxygen deprivation.
- Heart disease. Excessive panting and coughing can be a symptom of heart disease or failure, which can majorly impact your dog's ability to breathe. In these cases, you may notice your dog panting heavily after walking for a short distance.
- Heatstroke. Heatstroke in dogs is a serious issue and can have fatal consequences if left untreated. Heatstroke in dogs is more likely in temperatures over 106°F (41°C) and causes heavy panting, which leads to dehydration. High temperatures are especially hard on short-nosed breeds like pugs, but you must never leave a dog of any breed alone in a car in warm weather, as they can overheat or suffer from heatstroke quickly.
Why does my dog pant at night?
Below are some other common causes of panting and restlessness in dogs during the night:
- Stress or anxiety. This can be caused by upsetting events like loud thunderstorms or fireworks, or issues like separation anxiety.
- Environmental issues. Puppies and senior dogs have a harder time coping with high nighttime temperatures, and dogs with untreated allergies often have disrupted sleep.
- Pain or Discomfort. Dogs experiencing pain from an injury or a condition such as arthritis may exhibit nighttime panting and/or pacing behaviors. (e.g. injury, arthritis, allergies)
- Canine Cognitive Disorder (dog dementia). Dogs affected by this disorder often have disturbed sleep-wake cycles and may exhibit excessive panting and restlessness.
When should my dog see a vet?
If your dog shows signs of excessive nighttime panting, pacing, or other anxious behaviors, contact your veterinarian to see if your dog needs to be seen. If you notice any signs of heatstroke in your dog, take him to an urgent veterinary clinic during business hours or an emergency veterinary hospital after hours. Your veterinarian will examine your dog, perform any diagnostic and treatment procedures that are required, and collaborate with you to help your dog feel better today and tomorrow.
