Heart Failure or Lung Disease
Because the heart is not getting enough blood, dogs with these one of these two conditions will often pant to obtain more oxygen. If your pet has been diagnosed with one of these conditions already, talk with your vet about how potential treatment options and what you can do at home to make your pet more comfortable. If your pet has never been diagnosed, it's important to make a call to the vet for a checkup. Make sure to express your concerns over excessive panting so that this can be addressed in the physical exam or other recommended tests.
