The dog breeds at most risk of suffering heat stroke

Aussies have been warned to brace themselves for a scorching summer, and as temperatures soar, the risk of heat stroke in dogs escalates.

Heat stroke can severely threaten a dog's health, and certain dogs are more vulnerable due to their physical characteristics and genetic predisposition. 

Unfortunately, many dog owners don't recognise when their dog is overheating, as they will eagerly keep running and playing.

Being aware is the first step to ensure you take the necessary precautions to keep our dogs safe and ensure they enjoy a happy and healthy summer season.

These dogs are more likely to suffer heat-related illness during the hot Australian summer.

Brachycephalic breeds

Those with flat faces and short noses have limited airflow compared to dogs with longer snouts, and their anatomy makes it challenging for them to cool themselves by panting efficiently. This significantly increases their risk of heat stroke.

Senior Dogs

Older dogs, regardless of breed, may have reduced heat tolerance due to age-related physiological changes. Their ability to regulate body temperature diminishes, making them more susceptible to heat stroke.

Puppies

Puppies are especially susceptible to heat stroke as they are very active but don't have the ability to regulate their temperature properly.

Owners of these susceptible breeds must take extra precautions during hot weather. This includes providing plenty of fresh water, avoiding exercise during peak heat, ensuring access to shade, and never leaving them in a parked car or hot room. 

Recognising early signs of heat stress, such as excessive panting, drooling, agitation/ restlessness, bright red gums and laboured breathing is essential, as early intervention can be life-saving.
