Studies of dog bite injuries have reported that:
The median age of patients bitten was 15 years, with children, especially boys aged 5 to 9 years, having the highest incidence rate
The odds that a bite victim will be a child are 3.2 to 1. (CDC.)
Children seen in emergency departments were more likely than older persons to be bitten on the face, neck, and head. 77% of injuries to children under 10 years old are facial.
Severe injuries occur almost exclusively in children less than 10 years of age.
The majority of dog attacks (61%) happen at home or in a familiar place.
The vast majority of biting dogs (77%) belong to the victim's family or a friend.
When a child less than 4 years old is the victim, the family dog was the attacker half the time (47%), and the attack almost always happened in the family home (90%).
