Why do flat-faced dogs overheat?

Dogs are not able to sweat like humans and they rely heavily on panting to regulate their body temperature. Brachycephalic dogs have shorter muzzles and as a result, air-flow is restricted in and out of their mouth. This essentially makes it harder for them to effectively exchange hot air for cool, and they can easily overheat. Some of these dogs also have narrow nostrils (nares) making it even harder to draw in air to pant, putting them at greater risk of heat exhaustion. Brachycephalic dogs can be quite variable in terms of the degree of shortness of their muzzles and this means that some brachycephalic dogs will cope relatively well in the heat but others may find even a slight increase in temperature a challenge.

All brachycephalic dogs are at higher risk of overheating than dogs with a normal-length muzzle, but how acute this is can vary from dog to dog. The dogs with the flattest faces, shortest noses, and narrowest nostrils are those that will find heat the most challenging and so that will be in the most danger from exertion during summer walks. Being overweight can be far more serious, and impact on the dog’s breathing as well as comfort, and ability to stay cool. On very hot days, all dogs should be walked outside of the hottest times, which generally means early morning or in the late evening when the sun has gone in a while since. This is especially important for brachycephalic dogs, as even a level of heat that most dogs would be fine with as long as their exercise was moderate can be dangerous for a brachycephalic dog just walking along at a sedate pace. Flat-faced dogs don’t tend to be the most energetic ones and their general pace and natural activity levels tend to err on the side of slow and sedate, meaning they tend to need fewer walks and these at a more relaxed pace than most other dogs. However, what constitutes exertion is different for every dog; a slow canter around the park might not even increase the heart rate of the average springer spaniel, but for an English bulldog, they might not even make it all the way around and maintain healthy respiration without needing to stop several times to rest and recover.

Brachycephalic dogs are more likely to overheat because they often already struggle to breathe, even at rest. Effective panting is essential for cooling, as dogs cannot sweat like humans. Over a third of brachycephalic dog owners have previously reported their pet struggled with “heat regulation”. Most of the breeds at higher risk of heatstroke are brachycephalic. Brachycephalic dogs had twice the odds of suffering heatstroke than dogs with an average muzzle.

The poor ability of these types of dogs to keep themselves cool by panting because of their abnormally flattened faces means that they are at huge risk of heatstroke in hot weather. Due to their flattened skull shapes, flat-faced dogs do not have the naturally longer nose that helps other types of dogs to lose heat during panting, meaning flat-faced breeds often struggle more than other types of dogs to lose heat effectively. Dogs don’t sweat like humans do; instead the main way they cool themselves down is by panting. The limited breathing abilities of some flat-faced dogs means they often struggle to cool themselves down and ineffective panting in these dogs only further exacerbates their breathing difficulties. These problems are exacerbated in hot weather and especially if the dogs are exercised.

Brachycephalic dogs are the cute, personable breeds such as Bulldogs, Pugs, Pekingese and Boston Terriers. Their short noses and flat faces are an extreme disadvantage in hotter temperatures because the dog’s primary mechanism for beating the heat is panting, and these dogs do not pant efficiently. Panting is a form of evaporative cooling, and air must easily flow for the process to work. The shorter faces of brachycephalic dogs make them look adorable, but they create big problems for airflow. These dogs suffer from brachycephalic airway syndrome (BAS), which causes inefficient breathing and, therefore, inefficient cooling. Each of these structural problems interferes with how quickly air can pass to the lungs. If evaporation is the way a system cools, and little air is passing through, the system quickly overheats. Dogs can easily suffer from heat exposure, but brachycephalic dogs have the highest risk for heat exhaustion and heat stroke.

Brachycephalic dogs face a higher risk of heat-related issues due to their distinctive respiratory tract structure, making them more prone to heatstroke – a severe, potentially fatal condition. Their shortened skull structure impairs regular breathing, making cooling down through panting – a vital thermoregulation mechanism – more challenging. During hot weather or intense exercise, these breeds might struggle to reduce body temperatures, leading to heatstroke. These breeds, like Bulldogs and Pugs, have shorter noses and elongated soft palates, complicating their breathing process and making it harder for them to regulate body temperature. Their shortened airways restrict airflow, increasing their susceptibility to overheating and heatstroke compared to other breeds.

A lean and fit body helps with heat dissipation and allows for better air circulation, reducing the risk of overheating.

Dogs pant to cool down – without a nose, panting is simply less effective. In fact, brachycephalic dogs may even generate more heat simply gasping to breathe than they lose by panting. It’s likely that brachycephalic dogs overheat due to their intrinsically ineffective cooling mechanisms. The Chow Chow and the Golden Retriever, which were also at high risk, have thick double coats which limit effective cooling in hot weather, because the coat traps warm air against the body to prevent effective cooling from the skin. Many of the breeds that were at increased risk were flat-faced meaning that they had a ‘brachycephalic’ skull with a shortened head, flat face and short nose. The Bulldog, an extreme flat-faced breed, was 14 times more likely to develop heatstroke than Labrador retrievers, whilst flat-faced dogs in general were twice as likely. Dogs are unable to regulate their body temperature as well as humans do, so as the weather warms up, we need to be alert to the signs of heat stroke.
