Understanding Dog Bite Laws
What is Strict Liability?
In strict liability states, a dog owner is legally responsible for injuries caused by their dog regardless of whether they knew the dog was dangerous. The victim only needs to prove that the defendant owned the dog, the dog bit them, and they were legally allowed to be where the bite occurred.
What is the One-Bite Rule?
The one-bite rule (also called the “first bite free” rule) means owners may not be liable for the first bite if they had no reason to believe their dog was dangerous. However, once an owner knows their dog has bitten before or shown aggressive behavior, they can be held liable for future incidents.
Common Defenses
- Provocation: The victim teased, tormented, or abused the dog
- Trespassing: The victim was illegally on the owner’s property
- Comparative Negligence: The victim’s own actions contributed to the injury
- Assumption of Risk: The victim knowingly accepted the risk (e.g., veterinarians)
What to Do After a Dog Bite
- Seek medical attention immediately, even for minor wounds
- Document the incident with photos of injuries and the location
- Get owner information including name, address, and insurance details
- Report the bite to local animal control
- Consult an attorney to understand your legal options
Frequently Asked Questions
Can I sue if a dog bites me?
Yes, in most cases. Your ability to recover damages depends on your state’s laws. In strict liability states, you can typically sue without proving the owner knew the dog was dangerous. In one-bite states, you may need to prove prior knowledge or negligence.
What damages can I recover?
Victims may recover medical expenses, lost wages, pain and suffering, emotional distress, and scarring/disfigurement damages. Some states also allow punitive damages for particularly egregious cases.
Does homeowner’s insurance cover dog bites?
Most homeowner’s and renter’s insurance policies include liability coverage for dog bites. However, some insurers exclude certain breeds or dogs with bite history. Always check your policy.
What is the statute of limitations for dog bite claims?
Most states allow 2-3 years to file a personal injury lawsuit, but deadlines vary. Consult with an attorney promptly to ensure you don’t miss any deadlines.
Are certain breeds more dangerous?
While some studies suggest certain breeds are involved in more bite incidents, any dog can bite regardless of breed. Many states have moved away from breed-specific legislation, focusing instead on individual dog behavior and owner responsibility.
