Summers in the Seacoast can be beautiful, but for pets, especially dogs and cats, rising temperatures bring serious risks. One of the most dangerous and time-sensitive conditions we see in the ER at Port City Veterinary Referral Hospital is heat stroke.

What is Heat Stroke in Pets?

Heat stroke is a form of hyperthermia, when a pet’s body temperature rises dangerously high and they can no longer cool themselves efficiently. Dogs and cats primarily release heat through panting and limited sweat glands in their paws, making them more vulnerable than humans.

Common Signs of Heat Stroke:

• Excessive panting or drooling

• Lethargy or weakness

• Vomiting or diarrhea

• Bright red gums or tongue

• Collapse or unresponsiveness

Breeds at Higher Risk:

Flat-faced (brachycephalic) breeds such as Bulldogs, Pugs, and Persian cats are especially susceptible, as are senior pets, those with heart or respiratory conditions, and overweight animals.

How to Prevent Heat Stroke:

• Avoid walking pets during peak midday heat.

• Always provide cool water and shade.

• Never leave pets in parked vehicles, even briefly.

• Use cooling mats or vests when outdoors.
