Dog Heatstroke in Arizona: First Aid Before Veterinary Care
Share
Arizona heat can overwhelm a dog quickly. Dogs rely heavily on panting to lose heat, and short-nosed breeds, older dogs, overweight dogs, and dogs with heart or airway disease can be at increased risk.
Warning signs
Signs of heatstroke can include excessive panting, heavy drooling, weakness or drowsiness, confusion, vomiting or diarrhea, abnormal gum or tongue color, unsteadiness, collapse, or loss of consciousness.
Begin cooling while arranging veterinary care
Move the dog out of direct heat and into shade or a comfortably cool environment. Begin cooling with room-temperature or cool water and airflow from a fan when available.
Avoid immersing the dog in cold or ice water. Current veterinary first-aid guidance favors controlled cooling rather than extreme cold.
Go to a veterinary hospital
Heatstroke is an emergency. Cooling should begin promptly, but veterinary evaluation is still necessary even if the dog appears to improve.
Cooling is first aid. It is not the end of treatment.
