The temperature within a car can increase expeomtentoally for every minute a dog is inside their life is at risk. The greatest concern is the risk of heatstroke.

Heatstroke is a life threatening emergency and any dog experiencing it should be taken to see a veterinarian immediately.

Signs of heatstroke include;
•shade seeking
•difficulty breathing
•panting
•bright red tongue
•weakness
•depression
•vomiting or diarrhoea
•coma
•shock

With Heatstroke cases the sooner a dog is seen the better the outcome. The vet will cool Whitie, provide shock doses of fluid therapy, provide oxygen, and treat complications such as heart and kidney failure.

The psychological affects would be fear, anxiety and pain. All Of which can cause long term damage to the mental health of a dog.
