Many residents assume a calculator can translate medical bills into a fairly predictable payout. In practice, insurers in Illinois often focus on three things first:
- Whether the dog owner had reasonable control at the time of the incident (leash, fencing, supervision, and whether the dog had access to public-facing areas).
- Whether the injury is documented and consistent across medical notes, photos, and timelines.
- Whether the circumstances create a dispute about fault—for example, whether the bite happened near a walkway, during a delivery drop-off, or after the dog was provoked.
That’s why two people with similar bite locations can see very different outcomes: not because the calculator is “wrong,” but because the evidence and fault story are different.
