Normal Breathing in Dogs

Dogs have a normal respiratory rate somewhere between 20 and 34 breaths per minute. When a dog’s breathing normally, he won’t appear stressed or anxious. Breathing will be relaxed and easy.

It’s important to understand that each dog and dog breed is different, so what’s normal for one dog may be different in another dog. For this reason, it’s good to pay attention to your dog’s normal breathing, so you’ll be able to quickly recognize when he’s developed a breathing problem

Fast Breathing and Panting in Dogs

Let’s take a look at some of the most common causes of breathing hard and panting:

1). Exercise: panting after strenuous exercise is a way for dogs to cool themselves off. Canines don’t sweat like we do; instead, dogs use panting as a way to cool themselves off. If your dog is panting hard after running or playing, he’ll have a content look on his face, he won’t appear to be stressed. He’ll appear relaxed and happy.

2). Emotions: intense feelings and emotions can cause heavy panting in dogs, especially if they’re feeling stressed, depressed, afraid or anxious. However, even happy emotions and positive forms of excitement can cause a dog to breathe or pant fast.

3). Panting due to the heat: if the weather’s hot, your dog will pant. During hot weather, your dog’s body temperature increases, causing the body’s systems to help cool it down. Panting, with an open mouth, cools your dog off by evaporative cooling. The wet surfaces of your dog’s mouth help to lower his core temperature.

4). Heatstroke: is a medical condition that occurs when the body’s core temperature goes above the normal temperature. For a dog, a normal body temperature is around 103° F. If a dog’s temperature reaches up to 106° F, he could be suffering from heat stroke (also called heat exhaustion). This is a very dangerous condition which can lead to dogs collapsing, developing convulsions, vomiting and diarrhea, etc.

5). Pain: is another cause of heavy breathing and panting in dogs. Dogs that are panting hard and experiencing pain will looked stressed and may be restless, trying to find the most comfortable position possible. They may also tremble and shiver. Pain can be caused by arthritis, orthopedic conditions, abdominal pain, cancer and many other conditions.

6). Running a fever: heavy breathing or panting may also be caused if your fur baby’s developed a fever. There are many medical conditions that can cause a fever including infections such as abscesses, fungal or urinary tract infections, tick diseases, and more.

7). Overweight or obese: being overweight or even obese can cause your dog to breathe hard or pant. It takes extra effort to move that excess weight around. Your dog could even develop lowered lung function due to being overweight or obese.

8). Age: older dogs may breathe harder and pant. Just like us, dogs can develop lung issues and circulation problems as they age, making it harder to breathe and oxygenate their blood.

9). Medications: certain medications can cause dogs to pant or breathe harder. Steroids, such as prednisone, are known for causing this type of side effect. Opioid painkillers are also known for this unpleasant side effect in dogs.

10). Doggy Alzheimer’s: older dogs can develop a form of cognitive dysfunction sometimes referred to as “Doggy Alzheimer’s.” One sign of this condition is restlessness, panting episodes, not being able to sleep or get comfortable, etc. Dogs with this condition may even forget how to get out to potty, they may not remember verbal cues, etc.

11). Neurological problems: some neurological problems can cause heavy breathing or panting in dogs. Sometimes heavy, fast breathing may come before a seizure or due to a mass on the brain. You may also notice your dog falling down, or generally having trouble getting around.

12). Metabolic disorder: panting can also be caused by a metabolic disorder called Cushing’s Disease. This disorder is generally caused by an endocrine disorder, but can also be caused by corticosteroid medications. This medical problem causes a build-up of too much cortisol in a dog’s system. The dog may show signs such as panting, drinking a lot more water than usual, increased urination, hair loss and more.

13). Giving birth: a female dog may pant heavily after giving birth. After all, it’s hard work to bring a litter of little lives into the world. The momma dog may feel stressed, hot, along with mild contractions—all of which can lead to heavy breathing and panting.

14). Poisons: if your dog has been exposed to toxins and poisons in his food or environment, this could be the cause of his heavy breathing and panting. Dogs will eat almost anything—including things that aren’t good for them. Eating things they shouldn’t can cause these and other problems, including vomiting and diarrhea.

15). High blood pressure: another common cause of panting in dogs is high blood pressure. Dogs, in general, don’t develop high blood pressure like their pet parents. Instead, elevated pressure can be caused by an underlying medical condition such as kidney problems, Cushing’s disease, diabetes, etc.

These are some of the most common causes of hard breathing and panting in dogs. Even so, you may have some questions about your dog in combination with other symptoms. Next, we’ll look at some of the most common questions people ask about panting and fast breathing in their fur babies.
