Service dogs are trained to be calm and composed in public, but like any animal, they can bite if provoked.
Their calm demeanor is due to rigorous training that helps them manage stress and distractions.
Service dogs are not typically aggressive, but they can defend themselves if they feel threatened.
According to the article, service dogs are more likely to bite if they're not properly trained or if their owners are inexperienced.
In rare cases, service dogs may bite due to medical conditions or allergies that affect their behavior.

Liability and Risks
If you're bitten by a service dog, you can file a premises liability lawsuit against the dog's owner/handler. You can also potentially sue the owners of a restaurant or other business where the incident occurred.
The liability will be determined by the nature of your case, so it's essential to speak with a personal injury attorney as soon as possible. Dog bites can be nasty, and the damage can be permanent, especially if the victim is a child.
The owner or handler of a service dog may face legal consequences if their dog attacks another animal. In some cases, they may be held liable for damages caused by their service dog's attack.
If a service dog attacks another animal, the consequences may include animal removal, compensation for pain and suffering, or even criminal penalties. These consequences can vary depending on the jurisdiction.
To determine the liability and risks associated with a service dog attack, it's essential to gather necessary documentation, such as:
- Animal Removal – In some jurisdictions, an animal that has been involved in a service dog attack may be removed from the home and placed in a shelter or rescue facility.
- Compensation for Pain and Suffering – An animal attacked by a service dog may suffer physical pain and emotional trauma, which can have long-term implications.
- Criminal Penalties – Depending on the jurisdiction, an attack by a service dog may result in criminal penalties for the owner or handler.
Service Dog Incidents
Service dogs can bite, and it's a serious issue. In fact, a service dog bit two people at Denver International Airport, including an airline employee and a bystander.
The incident involved a Belgian Malinois named Bella, who bit the employee in the face and the bystander in the forearm. Both injuries were rated a level 4 on the Dog Bite Scale, but because they were combined, the incident was escalated to a level 5.

The responding officer didn't confirm whether the dog was a fully trained service animal or just in training. However, under the Americans with Disabilities Act, service animals in training are given the same protections as fully trained service animals.
The dog is currently being held at the Denver Animal Shelter on a 10-day bite quarantine, until May 6.

Service Dogs
Service dogs are trained extensively and specifically to meet the needs of their eventual owner, spending more than a year in a home where they are trained on good behavior.
These dogs are trained to react well and specifically in high-stress circumstances, making it highly unlikely that a dog bite will come from a traditionally trained service dog.
Service dogs have protections under the American with Disabilities Act (ADA), which is something to consider if a bite does occur.
Injuries and Attacks
Service dog attacks can cause a range of physical injuries, from minor bites and scratches to severe puncture wounds and deep lacerations.

Dislocations can occur if a service dog attack is particularly severe, requiring medical attention and physical therapy to heal fully. I've heard of cases where people have suffered dislocations in their joints or bones, which can be a real challenge to recover from.
Fractures are another possible outcome of a service dog attack, which can be difficult to heal without specialized treatment. In some cases, surgery may be required to repair the damage caused by the attack.
Trauma to the face and head can also occur, including lacerations, bruising, or even blunt force trauma. This can result in serious long-term damage, such as nerve damage, vision loss, or hearing loss.
Bites can result in infections if not properly cleaned and treated. Scarring and disfigurement may also affect the injured person, especially in cases where surgery is necessary to repair the damage.
Nerve damage is a potential long-term consequence of a service dog attack, which can lead to loss of function, numbness, and pain.
Here are some potential long-term effects of nerve damage:
- Loss of function
- Numbness
- Pain
