In Newton’s more residential neighborhoods and busy sidewalks, disputes commonly turn on control and foreseeability—especially when the bite happens in a place where people reasonably expect a dog to be restrained.
Common liability arguments we see in Massachusetts include:
- The dog wasn’t leashed or was able to access an area it shouldn’t have (front yards, porches, side gates, shared property areas).
- The owner claims the injured person provoked the dog—for example, reaching toward the animal or moving in a way the defense argues was threatening.
- The owner argues they had no reason to know the dog was dangerous, even if there were prior incidents or complaints.
- Causation disputes, where the insurer suggests the injury wasn’t caused by the bite or that later symptoms stem from something else.
A settlement can swing dramatically depending on whether liability is strong on paper and supported by consistent records.
