Panting during the day as you are playing with your dog or if the sun is hot can seem relatively normal, but what about during the night when your dog is trying to sleep? Today, our Montecito vets share some of the reasons why your dog may be panting at night and when you should worry.
When your dog is panting it is usually them trying to regulate their body temperature since they do not sweat as we do. Panting at night, however, is a different matter - especially when there is no obvious reason for the dog's distress.
What Are Some Reasons For Panting in Dogs?
There are a number of circumstances wherein your dog panting is no cause for alarm, such as after a long walk in humid weather, an energetic play session, or excitement. Panting and restless behavior (e.g. pacing) in mild or ideal weather conditions or during the night when it is cooler could be a sign of something more serious. Some of the potential reasons for excessive panting could include:
- 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 issues impact your dog's ability to breathe, making it hard for them to receive the oxygen their bloodstream needs to carry throughout their body. A dog with respiratory issues might pant heavily or struggle to breathe after even light exercise. If you notice your canine companion's tongue is no longer a healthy pink but instead blue, purple, or grey, head to the vet immediately for treatment; your dog may be experiencing 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 Might My Dog Be Panting 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.
Should I Bring My Dog to See a Vet?
If your dog exhibits symptoms of excessive nighttime panting, pacing, or other anxious behaviors get in touch with your vet to find out whether your dog should be seen by them. If you spot any signs of heatstroke in your dog, immediately take them for urgent veterinary care during clinic hours, or treatment after hours at a nearby emergency veterinary hospital. Your veterinarian will examine your canine companion, perform any necessary diagnostic and treatment procedures, and work with you to help your dog feel better today and tomorrow.
