What causes breathing difficulties in dogs?

There are many different reasons your dog may be having difficulty breathing.

Fortunately, the particular way that your dog is breathing often will give clues as to the cause of the issue. In fact, it’s always a good idea to try to capture a video of your dog’s breathing issue if you can (otherwise you may find yourself acting it out in the vet’s office!).

The following lists include the most common reasons for various types of breathing difficulties in dogs:

Laboured Breathing (Excessive Effort)

  • Heart disease (enlarged heart +/- congestive heart failure)

  • Paroxysmal Breathing (aka reverse sneeze syndrome)
  • Bloated or fluid filled abdomen (ie: dogs with a twisted stomach)
