Recent statistical studies on dog attacks have shown the potentially catastrophic nature of the injuries that can result from these attacks. Homeowners insurers paid out $882 million in liability claims related to dog bites and other dog-related injuries in 2021. Each day, nearly 1,000 people are treated in hospital emergency departments for nonfatal dog bite-related injuries. In 2018, nearly 27,000 people underwent reconstructive surgery as a result of being bitten by dogs. Approximately 4.5 million dog bites occur each year in the United States. There was an 86% increase in dog bite-related hospitalization stays between 1993 and 2008 in the United States. The average cost of a dog bite-related hospital stay was $18,200, about 50% higher than the average injury-related hospital stay. Dog attack victims suffer over $1 billion in monetary losses annually. JAMA reports this estimate to be as high as $2 billion.
