Wagging tails, perky ears and big sighs - all natural characteristics of dogs that we know and love! Another classic panting - one we often see after a day of running around the park or when the temperature is particularly high. Whilst painting can be normal dog behaviour, sometimes it can be a sign of something more serious. In this article, we’ll be delving into panting in dogs and when it is a cause for concern.

 

What is panting?

When we say ‘panting’ in reference to your dog, we’re referring to when they breathe heavily and loudly, often with their tongue hanging out. 

It often happens after your dog has finished exercising or has been laying out in the sun. It usually subsides after rest or when they’ve cooled down. 

That said, in some circumstances panting can indicate something else, and call for medical intervention.

 

 

Why is my dog panting?

There are many reasons why your dog could be panting:

Cooling themselves down

Dogs sweat a little from their paws and ears but are unable to sweat through their skin like we do. Due to this, they rely heavily on panting to help cool them down when warm. Warm air escapes the body while cooler air is inhaled. Water evaporation adds to the cooling effect. 

When it is warm, you’ll notice your dog pants. This is especially true if they’ve been exercising. This sort of panting is expected and will soon resolve once your dog is cool again. 

 

Over heating

It is important that owners can tell the difference between normal panting when warm and heat stroke. 

Dogs with heat stroke will pant excessively and may also have signs such as:

  • Glazed eyes
  • Red gums
  • Drooling
  • Wobbly walking

While the classic case of heat stroke occurs in those dogs locked in warm cars, dogs can develop heat stroke when outside too. Those most at risk are brachycephalic breeds who are over-weight.


Help keep your dog cool by avoiding the mid-day sun, offering plenty of water and using cool mats. Consider making your pooch a tasty ‘ice pop’ by freezing some wet Pooch & Mutt food inside a Kong. Remember, on a warm summer day you can keep your dog occupied with indoor games and training and don’t have to go on a walk.

 

Nerves, Stress and Anxiety

Panting can be a response to elevated cortisol (the ‘stress’ hormone) levels. Alongside panting, you may notice that your dog is restless, yawns and lips their lick. This sort of panting is something we see all too commonly at the vets. You may also find your dog does it at home if they suffer from separation anxiety or noise phobias. 

For anxious dogs, it is important we try to alleviate their symptoms. This usually means a combination of calming supplements, calming food (such as our Pooch & Mutt Calm and Relaxed) and behavioural modification. Consultation with a veterinary behaviourist is advised so they can address the underlying anxiety and help improve your dog’s quality of life. For very nervous dogs, discuss the possibility of a prescription anxiolytic medicine with your vet.

 


Underlying medical conditions

Sometimes, panting can be a sign of something more. 

Heart disease, lung disease, hormonal disorders and Laryngeal Paralysis can all result in dogs who pant at inappropriate times. 

Similarly, those in pain or who have a fever may also pant. You will notice that these dogs pant even when not warm or stressed. They may also have other signs such as a:

  • Cough
  • Lethargy
  • Wheezy breathing

Generally, these dogs are less able to exercise and cope in the heat.
Any unexplained panting requires veterinary attention. The vet will examine your dog, focusing on their heart and lungs. They may advise that some diagnostic tests are carried out, such as a blood test and chest x-ray.

 

Obesity

Dog’s can pant excessively due being overweight. This will often come after exercise like normal, but be a cause for concern when the activity wasn’t particularly very vigorous like going for a walk or climbing stairs. 

A vet can confirm if your dog is not at the required weight for their age and breed. If they deem them overweight or obese, they will suggest a low-fat diet and exercise to help them drop the weight back to a healthy amount.

 

 

FAQs

Why does my dog pant in the car?

Dogs can pant in the car for a number of reasons. Cars can get particularly warm in the summer due to dark interiors and the small space. If you dog is panting in the car due to heat, be sure to turn on the air conditioner or crack the windows open to a safe height where it allows air to circulate, especially if leaving them in the car.

Nervousness and stress is common for some dogs when it comes to travelling. If your dog is a nervous traveller, this can lead to them panting. Be sure to work on desensitisation training or treating your dog to calming supplements to help them relax during car journeys.

Why is my female dog panting?

A female dog can pant for all the same reasons a male dog does. However, a female dog can pant more during their heat cycle, and when in labour.

Why is my puppy panting?

Puppies can pant for all the normal reasons a dog can including temperature regulation, exhaustion and nerves, stress and anxiety. However, just like older dogs, excessive panting can also mean underlying health conditions. If your puppy is panting and won’t stop, be sure to contact a vet immediately.

Why is my dog panting at night?

It could be that it’s a particularly hot night or they’re sleeping somewhere new for the first time and it’s causing them stress and anxiety. However, if you dog starts panting at night for no particular reason, it could indicate an underlying medical condition or that they are in some pain and discomfort. If your dog continues to pant, be sure to contact your vet immediately.

Why does my dog have foamy saliva?

When your dog pants, you may notice some bubbles or foamy saliva on their tongue or around their mouth. Excessive panting from heat or exercise can make their saliva bubbly, but can also indicate they’re dehydrated or they’re overheated. If you’re worried about their foamy saliva or it appears alongside other concerning symptoms, be sure to contact your vet.
