This diagram says it all. Dogs thermoregulate by panting. Brachycephalic breeds, i.e. Bulldogs, Pekingese, Pugs, are at tremendous risk for heat stroke on even a warm day.
Once they start panting, if they cannot cool down in a timely manner, they pant harder, they get hotter, and then they pant harder, and then they get hotter..... And then fluid fills their lungs and their brains herniate.
Please pay attention to your pets. If you would like a consultation to help your bulldogs breathe better, please call Family Pet Clinic of Redondo Beach for a Brachycephalic Obstructive Airway Syndrome consultation with me.
