What are the reasons why a dog keeps panting?

There are several main reasons why a dog keeps panting:

Fever: When a dog has a fever, their body temperature rises, causing them to pant continuously.
Pain: Pain can cause a dog to pant as a way to alleviate themselves.
Seeking oxygen: Some dogs with narrower respiratory tracts may pant heavily to seek oxygen.
Heat: When it's hot, dogs pant to increase their heat dissipation.
Cardiopulmonary issues: Dogs with heart or lung problems may pant due to difficulty breathing.

When a dog keeps panting, it's essential for the owner to pay close attention to the dog's condition and monitor their temperature. It's best to seek medical attention promptly to diagnose the cause.

Fever:

When a dog has a fever, their nose is often wet. If the dog's nose becomes dry, and their paws are warm, it indicates a fever. The dog needs to be taken to a veterinary hospital for inspection and treatment.

Pain:

Pain can cause excessive anxiety in dogs, leading them to pant to relieve themselves. Check the dog's skin surface for wounds or swelling. If found, promptly tend to the wounds to prevent them from worsening.

Seeking oxygen:

Some dogs with narrower respiratory tracts may pant heavily to seek oxygen, such as Pugs, French Bulldogs, or Boxers. Their flat faces make it less efficient for them to pant, making them more susceptible to heatstroke or overheating. It's recommended to avoid vigorous exercise for these dogs.

Heat dissipation:

Dogs don't have sweat glands in their skin, so they rely on panting to dissipate heat. When it's hot, dogs pant to increase heat dissipation. In summer, it's important to help dogs cool down to prevent heatstroke. However, it's not suitable to lower the temperature in a cold air-conditioned room.

Cardiopulmonary issues:

Dogs with heart disease may pant continuously due to difficulty breathing. Clinical symptoms include heavy breathing, pale or purple mucous membranes, avoiding intense exercise, and abnormal heart sounds.

Additionally, when a dog's lungs are infected with bacteria, they may pant due to rapid breathing. Clinical symptoms include coughing, thick phlegm in the throat, increased oral secretions, rapid breathing, and cyanosis. If a dog exhibits these abnormalities along with continuous panting, it's essential to take the dog to a veterinary hospital for inspection and treatment.
