Don't go near or try to feed a strange animal. It's better to enjoy these animals at the zoo, in books, or on the Internet . To keep animals such as bears or wolves away from your campsite, keep it clean. Don't leave anything that is scented, such as deodorant or toothpaste, out in the open. Keep food packed away so that if Yogi the Bear does come along, he won't smell it and eat your dinner.
Scent is very important to animals in the wild because they use their sense of smell to hunt.
Most importantly, when you're in the wilderness, remember that you're on the animals' turf and you should respect their home as if it were your own. For specific medical advice, diagnoses, and treatment, consult your doctor.
