“Why Is My Dog Breathing Heavy While Resting?” Causes and What to Do

Milo, a gorgeous Border Collie, has been breathing heavily lately, even though he’s resting. He otherwise seems fine, but it’s still strange, as he never did that in the past.

Don’t worry, Milo is fine now, but this situation is common. If it happens to your puppy, there’s no need to google the question, “Why is my dog breathing heavy while resting?” Read this quick guide instead. 

Understanding your dog’s resting respiratory rate is crucial, and monitoring it can help unravel underlying health issues. We’ll tell you about this, the causes, and how the Maven Pet Health Monitor can track the rest respiratory rate and detect subtle changes automatically. 

What Is Normal Resting Respiratory Rate in Dogs?

Before worrying about your dog breathing fast but not panting, you need to understand its resting respiratory rate. The rate is the number of breaths your pooch makes per minute. The normal rate for pet wellness is 10 to 35 breaths, while the exact number depends on your dog’s age and size. 

If your puppy takes more than 35 breaths, this is an increased and abnormal resting respiratory rate. It’s crucial to visit your vet so they can uncover the underlying cause. 

At the same time, you can use the Maven Pet Health Monitor to monitor the rate automatically instead of making your own evaluations, which can be daunting and complicated. 

The device tracks the respiratory rate and continuously compares it to your dog’s unique baseline. It will also notify you of any changes so you can discuss with your vet the reasons for your dog breathing heavily through the nose.

Why Is My Dog Breathing Heavy While Resting?

There are many causes for your dog’s heavy breathing. We can separate them into normal and concerning causes. 

Here are the normal causes:

  • When the dog is dreaming or in REM sleep, brief increases in the breathing rate are common. 
  • Mild anxiety or excitement can lead to increases in the resting respiratory rate. 

As for the concerning causes, here’s what you need to know:

  • Respiratory issues — Various respiratory issues can be the cause, like an infection or allergies. However, you’ll likely see other symptoms, too, like coughing, night restlessness, and nasal discharge. 
  • Heart conditions — If the underlying cause is a heart condition, symptoms like lethargy and decreased activity are also likely.
  • Overheating or heatstroke — In the case of a heat stroke or your pooch overheating, it’s crucial to take immediate action and monitor for changes. AVMA has a few suggestions for keeping your pet safe from overheating in warm weather
  • Discomfort or pain — Whenever your dog is in pain, it will likely start breathing more heavily than usual. In such cases, the Maven Pet’s ability to detect behavioral and activity level changes can be of great assistance.

Besides these, there are various other reasons for a dog breathing heavily while resting, and it might be worth knowing about them, even though you should still rely on your vet to determine what’s wrong with your pup. 

It’s worth noting that the reasons for an older dog breathing heavy while sleeping are not always easy to find.  

When Should You Worry About Heavy Breathing?

You shouldn’t start worrying, but you should start acting as soon as you notice one or more of these red flags:

  • Persistent rapid breathing during rest
  • Coughing, wheezing, and nasal discharge
  • Blue-tinged gums (cyanosis)
  • Unusual lethargy
  • Loss of appetite

The Maven Pet smart collar can greatly help here as it will help you act on time. It will track patterns like prolonged inactivity or night restlessness. 

These behavioral patterns can point to potential health concerns that must be addressed soon to keep your puppy healthy.
