Metabolic Acidosis
Metabolic acidosis is characterized by increased acid production due to metabolism or the reduced excretion of acids. It is relatively common in dogs, and it is most often secondary to another more serious condition. Conditions such as diabetic ketoacidosis, renal failure, or respiratory dysfunction and poisoning are primary conditions that contribute to metabolic acidosis, and each must be treated in order to restore the pH balance to appropriate levels. Treatments may include dialysis, medication, or the administration of oxygen.
Getting Too Excited
Does your dog seem to hyperventilate any time you have company? Does she pant irregularly when she knows you are going to the dog park or out for a walk (activities that she regularly enjoys)? It is possible that your dog hyperventilates simply because she gets overly excited at the thought of doing something she enjoys. There is no treatment for this type of hyperventilation; however, your vet can prescribe medication if the hyperventilation presents a significant problem. Note that it is always best to rule out a respiratory ailment, heart problem, or other infection that could be causing the hyperventilation.
Stress
While dogs can hyperventilate because of sheer happiness, they can also hyperventilate because of fear and/or stress. Thunder, fireworks, loud noises – all these can illicit hyperventilation in your dog. Usually, hyperventilation is not the only symptom your pet will exhibit when stressed. Dogs exhibiting stress will often whine or cry, yawn repetitively, pace, tremble, or hide in addition to hyperventilating. Rarely, dogs experiencing stress will break housebreaking habits and lose control of their bladder or bowels. Stress can be caused by the aforementioned situations, but trips to the vet or dog groomer or strange visitors can also frighten your dog. Your vet can prescribe medications to help them deal with anxiety.
Other Breathing Difficulties
If all other possibilities for hyperventilation have been ruled out, it is possible your dog is suffering from other ailments such as overheating, pain, Cushing’s disease, anemia, or laryngeal paralysis. Overheating due to heatstroke can cause a dog to pant rapidly, imitating hyperventilation. Pain, like stress or excitement, can also cause excessive panting. Cushing’s disease causes the adrenal glands to excrete excessive cortisol, which can cause heart ailments. Brachycephalic dogs may also exhibit excessive panting or seem to be hyperventilating due to their elongated soft palate. Brachycephalic dogs should never be allowed to get overly hot or exercise excessively due to their abnormalities which already predispose them to breathing difficulties.
No matter the cause of your dog’s excessive panting, you should always have her examined by a vet to rule out possible life-threatening ailments.
