Signs of overheating pets include excessive panting, drooling, difficulty in breathing, vomiting, diarrhea, increased heart rate, bright red gums, confusion, loss of consciousness, and collapse.
When your dog is having a heat stroke, immediately remove it from the hot environment and give it plenty of water to drink but without forcing it. Apply icepacks on its back or soaked towel to cool it off and proceed to your vet as soon as possible.
Treatments include intravenous fluid therapy to replenish lost fluids and minerals. The vet will also look for possible kidney failure, neurologic disorders, abnormal clotting, variations in blood pressure, and unusual levels of potassium and sodium.
An important thing to remember in preventing heat strokes is making sure that your dog is in a well-ventilated area with enough shade and drinking water. Also, when traveling, make sure never to leave your pet unattended and alone inside the car for a long time.
