Dogs in Illinois take the second-biggest bite out of State Farm’s claim expenses nationally, accounting for the most bites and total payouts nationally after California. Florida, meanwhile, has among the most costly incidents on average. For the first time, the nation’s biggest home and auto insurer released the top 10 states for dog bite claims and the amounts paid out as a result of chomping pooches. Illinois – the nation’s fifth most populous state -- ranks second in the number of dog-bite insurance claims and highest total payouts, after population-leading California.
