WCIA-TV News (July 29) – After a dog died of heatstroke recently in Danville, Dr. Caroline Tonozzi, chief of the small animal emergency and critical care service at the University of Illinois Veterinary Teaching Hospital, was asked what owners can do to address signs of heat distress in their pets. She recommends using lukewarm or cool water to pour over your dog. You can also soak towels in water and put them on the dog. However, your top priority should always be contacting a veterinarian.
