What child doesn't love to pet a cute dog in the park? Unfortunately not all dogs want to reciprocate with a happy lick on the face. Some bite.

In fact, according to the National Association for Human and Environmental Education more than four million people in the U.S. are bitten by dogs. About 60 percent of those bitten are children younger than 13 years old.

Dog bites aren't always from strange dogs. Dog bites can happen in the home, when you least expect it. Jaci Duffina's son, of Temple, Texas, was just 3 years old when he was bitten by her sister-in-law's cocker spaniel. Fortunately, the bite left only a small laceration.

Although not all dog bites can be prevented, understanding man's best friend can significantly reduce the chance of your child being bitten.
