Respiratory system infection, heart disease, pulmonary edema, ascites, etc. can cause dogs to have shortness of breath and keep panting. It is recommended that owners take their dogs to the hospital for examination to determine the specific cause, and then consult a doctor for medication.

Why does my dog keep panting?

If your dog keeps panting, it may be caused by hot weather or strenuous exercise. At this time, take your dog to a cool place and rest for a while to recover. Dogs are different from humans in that their sweat glands are only distributed on their noses and paws. When it is hot, dogs need to breathe, pant and stick out their tongues to dissipate body heat and maintain a constant body temperature.
