READING PASSAGE 2
Read the passage carefully and answer the questions below.
I.Pet owners "sometimes judge heat by how they feel, and that's not what we need to do," says Barbara Hodges, a veterinarian and director of advocacy and outreach for the Humane Society Veterinary Medicine Association, located in Davis, California. Animals physiologically deal with heat differently than humans do. To regulate body temperature, we sweat through our skin, head to toe, and the sweat evaporates, cooling our bodies. Dogs and cats sweat only through their paws and noses; rabbits and birds don't sweat at all. Dogs rely on panting as their primary way of cooling down-it allows water to evaporate across their lungs, tongues, and moist surfaces of the mouth.Cats typically groom their fur to keep cool; the saliva evaporates off their fur. While it may be tempting to shave your furry pet in the summer to help them stay cool, don't do it, says José Arce.veterinarian and president of the American Veterinary Medical Association. It may seem counterintuitive, but fur acts as an insulator; it helps keep animals warm in winter and cool in summer. Plus, it protects them from sunbum, something they're as susceptible to as humans.
II. While pets have adaptations to deal with normal summers, they don't cope with extreme heat."says Hodges. Extreme heat. "can overwhelm an animal's thermoregulation, preventing them from shedding that excess heat and eventually leading to heatstroke, which can be fatal," Arce says. All pets are susceptible to heat stroke, but some are at higher risk, Arce says. Brachycephalics-short-headed dogs like pugs, bulldogs, French bulldogs, and Boston terriers-have narrow windpipes and can have trouble exhaling air, which means they may have trouble keeping themselves cool.
