More than 4.5 million people are bitten by dogs each year in the United States, and more than 800,000 receive medical attention for dog bites, according to the U.S. Centers for Disease Control (CDC). At least half of those bitten are children. Here are more dog bite facts: Almost 1 in 5 people bitten by dogs require medical attention. Children are the most common victims of dog bites and are far more likely to be severely injured. Most dog bites affecting young children occur during everyday activities and while interacting with familiar dogs. Any dog can bite: big or small, male or female, young or old. Even the cuddliest, fuzziest, sweetest pet can bite if provoked. Remember, it is not a dog's breed that determines whether it will bite, but rather the dog's individual history and behavior.
