Anemia is a condition is which the red blood count is below average in the body. Because these cells transport oxygen to tissues in the body, and this little amount of oxygen is not enough, dogs will pant to make up for the loss. Dogs with anemia can live very long and healthy lives, but it is important that if signs are shown, your pet is diagnosed as soon as possible. If your dog's panting is found to be caused by anemia, you will need to discuss treatment options with your vet, including changes in diets and medication. Untreated anemia may lead to a need for a blood transfusion, so it is important to express your concerns with your vet as soon as you notice distressing symptoms.
