You probably have a first-aid kit at home for your family—but what about your family pets？You need to be ready if your furry friend faces an emergency at home. What's more，as the weather gets warmer，more pet owners take their pets with them when they leave the house—on vacation，to the park，jogging，hiking and even swimming. That can be fun for you and your pet，but there's a chance that your pet will get hurt there，as well. So，it's important to know some of the basics of first aid for your pet if necessary.

If your pet is exposed to long periods of heat and sunlight，she will be easy to get heat exhaustion（衰竭）or heatstroke. Signs of heat exhaustion are breathless，anxiousness，dry gums and red skin most easily seen on the ears.

If either of these occurs，cool the pet right away and，as always，get her to the vet（兽医）.Put the animal in a shaded or air-conditioned area，and wet the body with cool water. Rubbing isopropyl alcohol（异丙醇）on the belly and fanning the area will help drive away the heat. If a pet is suffering from heatstroke，don't try to give her water. Get her to the vet immediately.

If you see an animal that's been hit by a car，or you hit one accidentally，first be cautious of all oncoming traffic before trying to reach the animal. Approach carefully. Even a severely injured animal can bite you.

As someone helps with directing traffic, cover the animal with a blanket or towel. If the animal cannot stand on her own, there's a good chance that there are neck, back or head injuries, so try to gently transfer the animal to a flat surface. Then transport that flat surface to the nearest vet. Picking up or hand-carrying the animal may worsen the injuries.
