Dog Attack Bicycle Accident Lawyer

Based on cases we’ve handled, here are the most frequent bicycle accidents caused by dog attacks:

• Direct collisions. This happens most often on quiet streets when dogs escape from their yards or pull away from their owners. The impact almost always results in a fall, and dog bites may occur during the collision.
• Swerve accidents. When you see a dog rushing towards you, you only have seconds to respond. Many cyclists instinctively swerve away, losing control and colliding with vehicles, curbs, or other obstacles.
• Chase incidents. A dog’s sudden barking, lunging, or chase behavior can startle a cyclist into losing control. These accidents often end in high-speed crashes.
• Multi-dog encounters. With dogs approaching from various directions, there’s usually nowhere safe to turn. Pack behavior can make even a typically calm dog aggressive, and these situations often lead to the most severe crashes.
• Off-leash and unleashed dog incidents. When an unleashed dog runs into a cyclist’s path, the owner’s failure to comply with leash law requirements makes their negligence easier to establish in a legal claim.
• Retractable and extended leash accidents. Even leashed dogs can cause serious crashes. Retractable leashes and long leads create nearly invisible trip hazards when owners let dogs cross bike paths or sidewalks. A thin leash line stretched across a cyclist’s path at wheel or leg height can send a rider over the handlebars with no time to react. The owner’s failure to keep the leash short and the dog close creates clear grounds for a negligence claim.

In most cases, responsibility falls on the dog’s owner. Because dog bite laws vary by state, the specific legal theory depends on where you live.

• Strict liability. More than half of U.S. states have strict liability statutes for dog-related injuries. In many jurisdictions, including California, owners are liable if their dog injures a cyclist, regardless of the animal’s past behavior. Massachusetts holds owners strictly liable under MGL c. 140, § 155, and California Civil Code § 3342 follows the same principle. The Illinois Animal Control Act (510 ILCS 5/16) applies the same strict liability standard. Washington’s statute (RCW 16.08.040) holds owners responsible regardless of “the former viciousness of such dog or the owner’s knowledge.” Florida imposes strict liability under § 767.04, which applies whether the dog has bitten before or not. You don’t need to prove the owner was careless, only that their dog caused your injuries.
• The one-bite rule. Some states still follow the “one-bite rule.” An owner may not be liable unless they had prior knowledge of the dog’s aggressive behavior or dangerous tendencies. Evidence of a previous bite, lunging, growling, or chasing can establish the owner’s knowledge.
• Negligence. Dog-related bicycle accidents often involve non-bite injuries. If a dog causes a crash by chasing, barking, or knocking a cyclist down without biting, the owner can still be held liable under negligence laws, even when no physical contact with the dog occurred. A dog that chases a cyclist into traffic or forces them to swerve into a curb has caused an injury just as real as a bite, and the owner’s liability applies the same way. In every state, a pet owner can be held liable under general negligence law. Your attorney will need to prove duty of care, breach of duty, causation, and damages.
• Negligence per se and leash law violations. When a dog owner violates a local leash law, the violation itself is treated as automatic evidence of negligence.
• Comparative negligence. In states that follow comparative negligence rules, if a cyclist is found partially at fault, their compensation may be reduced by their percentage of fault.
• Third-party liability. Landlords can be held liable if they knew about a dangerous dog on their rental property and failed to act. Dog walkers, pet sitters, or kennel operators may also bear liability.
