How to Prove Negligence in a Dog Bite Case

Ronald S. Weiss, Attorney & Counselor Aug. 5, 2025

Dog bite incidents are, many times, devastating incidents that leave victims with physical injuries, emotional trauma, and mounting medical bills. For victims in Ohio and Michigan, pursuing a legal claim for compensation typically revolves around proving negligence. This process can be complicated, but with the right legal guidance, you can pursue the justice you need.  

At Ronald S. Weiss, Attorney & Counselor, serving clients in both Michigan and Ohio, we understand the challenges dog bite victims face, and we are committed to explaining the key legal considerations required to establish negligence in these cases.  

Understanding Negligence in Dog Bite Cases  

Negligence is a legal concept that involves proving that the dog owner, or another responsible party, failed to act in a reasonable manner, leading to your injury. Dog bite laws vary between Ohio and Michigan, so it’s essential to understand the relevant statutes in each state.  

Both Ohio and Michigan follow a strict liability rule for dog bite cases. This means that a dog owner can be held liable if their dog bites someone without provocation, regardless of whether the dog exhibited any previous signs of aggression. In any case, strong evidence and legal arguments are required to demonstrate negligence and establish the liability of the responsible party.  

Elements Required to Prove Negligence  

To prove negligence in a dog bite case, you (the plaintiff) will need to establish the following elements clearly and convincingly in court or during settlement discussions.  

1. Duty of Care  

You must be able to show that the responsible party owed you a duty of care. This duty often falls on the dog owner, who has an obligation to make sure their dog does not pose a threat to other people. For example, a dog owner has a duty to leash their dog in public areas or control them within the confines of their property.  

Your attorney can help identify the specific responsibilities imposed by state law or local ordinances, as these can significantly influence the owner’s duty of care. For instance, leash laws in many Ohio and Michigan communities mandate that dogs must be under control at all times. Failure to adhere to these laws can establish a violation of duty.  

2. Breach of Duty  

You must demonstrate that the dog owner breached their duty of care. This typically means showing that the owner was careless or negligent in managing their dog. Common breaches include allowing a dog to roam without a leash, failing to erect proper fencing on their property, or ignoring prior signs of aggressive behavior in their pet.  

Your attorney can help you gather proof such as eyewitness testimonies, surveillance footage, or prior records of the dog’s aggressive incidents to establish that the owner failed to act responsibly.  

3. Causation  

Causation is a critical component of proving negligence. Essentially, you must provide evidence showing that the owner’s breach of duty directly caused your injury. For example, if an owner failed to properly secure their property, and the dog escaped and bit someone, this establishes causality.  

However, the defense may attempt to argue that other factors led to the injury. Your attorney will meticulously investigate your case to counter such arguments and make sure the connection between the negligence and the injury is irrefutable.  

4. Damages  

You must provide a clear account of the damages you have suffered as a result of the bite. Damages can include physical injuries, medical bills, lost wages, emotional trauma, and ongoing pain and suffering.  

Your attorney will work closely with medical professionals, financial experts, and psychologists to compile strong documentation of your losses. By clearly presenting the financial and emotional toll of the incident, you can establish a stronger argument for pursuing full compensation for your injury. 

The Importance of Gathering the Right Evidence  

Proving negligence in a dog bite case requires a combination of strong legal strategy and compelling evidence. Some of the key types of evidence you should include when filing a claim for compensation include the following: 

  • Medical records: Provide documentation of the injuries you sustained during the attack, along with details about any ongoing treatments. This can support your claims of physical and emotional damage.  

  • Photographic evidence: Provide photos of the wounds, the location of the incident, or the dog in question to visually highlight the severity of the event.  

  • Eyewitness testimony: Include statements from people who observed the attack or any prior behavior exhibited by the dog and who could be instrumental in providing testimony about the owner’s negligence.  

  • Animal control reports: Submit records from animal control authorities that show any past complaints or incidents involving the dog.  

  • Expert opinions: If necessary, your attorney can connect you with veterinarians, animal behaviorists, or safety experts who may be able to provide testimony to verify the dog’s temperament or the owner’s failure to control it adequately.  

Common Defenses Used by Dog Owners 

It’s also important to prepare for defenses the dog owner might use. Some common tactics include arguing that the victim provoked the dog or trespassed on the owner’s property. Both Michigan and Ohio laws take such factors into account, which could potentially reduce or negate the owner’s liability.  

It's essential to consult with an experienced attorney who can anticipate these defenses and work to dismantle them with thorough evidence and effective legal arguments. For example, at Ronald S. Weiss, Attorney & Counselor, we work hard to challenge claims of provocation by examining the circumstances leading up to the bite and making sure the victim’s actions were reasonable and lawful.
