What is heatstroke?
With the recent heat wave it’s very important to be aware of the signs of heat stroke!
Heatstroke is a state of hyperthermia (elevated core body temperature above the normal range) resulting in heat injury to tissues. Heatstroke occurs when heat generation exceeds the body's ability to lose heat.
What are the main predisposing factors for Heatstroke?
A warm/hot, humid environment with inadequate ventilation
(e.g. due to weather conditions or animals being left in an unventilated room or car)
Inadequate shade
Inadequate drinking water
Excessive exercise
Be aware of the symptoms and look out for the signs in your pet.
These include:
Panting which increases as heatstroke progresses
Drooling, salivating
Agitation, restlessness Very red or pale gums
Bright red tongue
Increased heart rate
Breathing distress
Vomiting Diarrhoea (possibly with blood)
Signs of mental confusion, delirium
Dizziness, staggering
Lethargy, weakness
Muscle tremors
Seizures
Collapsing and lying down
Little to no urine production
Coma
HEATSTROKE IS A VERY SERIOUS, LIFE THREATENING CONDITION: IT CAN CAUSE DAMAGE TO YOUR PET'S INTERNAL ORGANS, SOMETIMES TO THE POINT WHERE THEY STOP FUNCTIONING AND CAN BE RAPIDLY FATAL - IT REQUIRES URGENT TREATMENT.
Preventing heatstroke
The good news is that you can help to prevent heatstroke by ensuring your pets are kept in appropriate environmental conditions and being aware of the symptoms so action can be taken swiftly.
