Offer on property w/ dog bite record lawsuit?

[Cynthia Archuleta]

The property i'm looking into shows a dog bite on the records in recent history. My question is, if the person that was bit chooses to sue, am i not involved since it happened prior to my acquiring, or are you still open to risk. Do i need some clause added in closing. Indemnification? Anyone in Wisconsin deal with prior litigation or litigation potential and how did you protect yourself? Lawyers chime in. Thanks!
