In many states dog bites are a strict liability on the owner of the dog. This means that the owner is responsible for any damages done by the dog whether or not the owner was directly at fault.

The injured person may not be able to collect any damages if the dog's owner can prove that the injured person was trespassing or provoking the dog causing it to bite.

If you were bitten by a dog or other animal at the fault of the owner contact a personal injury lawyer.
