Dogs are one of the most popular pets in the United States and can be wonderful companions and service animals. However, they can also cause serious injuries. Every day, about 1,000 people go to the emergency room due to dog bite injuries. Dog bites also result in about 14,000 hospitalizations every year. The fear often lasts much longer. Maybe you flinch when a neighbor’s dog barks. Maybe you’ve stopped walking your own dog down your street, or the attack replays in your head when you try to sleep.
Here’s what we want you to know. What you’re feeling is a real response to a frightening event, and for some people it develops into post-traumatic stress disorder (PTSD). Massachusetts law may also allow you to hold the dog’s owner responsible for that harm, not only for the physical wounds. Let’s walk through both.
Can a Dog Attack Cause PTSD?
It can. PTSD is a psychiatric condition that may develop after a person experiences or witnesses a traumatic event. A sudden attack, where you or someone you love could have been seriously hurt, fits that description.
PTSD is more common than many people think. The American Psychiatric Association estimates that about 6% of U.S. adults will have PTSD at some point in their lives. Women face a higher risk. The VA’s National Center for PTSD puts lifetime rates at about 8% for women and 4% for men.
Not everyone who goes through a trauma develops PTSD. Past experiences and the support you have afterward can both play a part.
Is It Trauma, Acute Stress, or PTSD?
Strong reactions in the first few weeks are common. The APA describes acute stress disorder as symptoms that appear between three days and one month after a traumatic event. A PTSD diagnosis requires symptoms that last more than a month and cause significant distress or trouble with daily life. Many people notice symptoms within three months, though they can show up later.
Only a licensed mental health professional, such as a psychiatrist or psychologist, can diagnose PTSD. So if you’re still struggling a few weeks after the attack, that’s a good time to get evaluated rather than wait it out.
Symptoms of PTSD After a Dog Bite
The APA groups PTSD symptoms into four categories. After a dog attack, they often show up like this:
- Intrusive Thoughts: Intrusive thoughts can include nightmares, memories, and flashbacks. Some people experience intense flashbacks that make them feel like they are reliving the traumatic experience.
- Changes in Mood and Cognition: People with PTSD may be unable to remember all or a portion of the traumatic event. They may develop self-esteem issues or feel negative emotions toward others. They may have difficulty experiencing positive emotions and lose interest in activities they previously enjoyed.
- Avoidance: People with PTSD may avoid places, people, objects, activities, and situations that trigger disturbing memories. They may also attempt to avoid thinking about or remembering the traumatic event and resist talking about the event or how they feel about it.
- Changes in Reactivity and Arousal: People with PTSD may be prone to angry outbursts, irritability, and self-destructive or reckless behavior. They may become easily startled, suspicious, and overly watchful of their surroundings. They may also have difficulty sleeping and concentrating.
Some people who do not have PTSD may experience some or all of these symptoms after a traumatic event. To receive a PTSD diagnosis, the symptoms must last for at least a month and must cause significant distress or difficulty with daily functioning.
For many people, symptoms begin within three months of the traumatic event. However, it can take longer for symptoms to appear, and some people may experience symptoms for months or years. Many people with PTSD also experience depression, memory problems, substance abuse, and other mental and physical health issues.
Why Some Dog Attacks Hit Harder
Not every attack leaves the same kind of mark. Who the dog belonged to, where it happened, and how people reacted afterward can all shape how the fear shows up.
- When it’s a dog you know. Many people we talk to were bitten by a dog they trusted, like a relative’s or neighbor’s pet. That sense of betrayal can be hard to shake, and self-blame often comes with it.
- When it’s a stranger’s dog. A dog that bolts out of a front door or escapes a yard can make your whole neighborhood feel unpredictable. People start changing routes or avoiding walks altogether.
- When you were protecting your own dog. This comes up often. You’re walking your dog on a leash, a loose dog charges, and you step in. You end up bitten, knocked down, or hurt pulling the dogs apart. Now you’re carrying your own injuries and the fear that it could happen again.
When the owner brushes it off. Hearing “nothing really happened” can make you doubt your own reaction. Their opinion doesn’t change what you went through.
Are Children at Greater Risk of Trauma?
Kids are among the most frequent dog bite victims. According to the AVMA (2026), more than 4.5 million people are bitten by dogs in the U.S. each year, and children account for at least half of those injuries. Young children are also more likely to suffer severe bites to the head and neck.
Children can’t always put fear into words. Instead, it may show up as nightmares, clinginess, refusing to go outside, or acting out the attack in play. Research backs this up. In a 2004 study in The Journal of Pediatrics, 12 of 22 children treated for dog bites had PTSD symptoms lasting more than a month. A 2024 research review in Children also points to a study where 70% of parents noticed new, alarming behaviors in their child after a bite.

How a Dog Attack Can Affect Your Work, Money, and Daily Life
Deep punctures may need stitches, antibiotics, or surgery, and some bites leave lasting scars. When PTSD is part of the picture, the impact often reaches further.
You might miss work for therapy appointments. A delivery driver or home health aide may feel unable to approach homes with dogs. A parent may no longer walk their kids past a certain house. Therapy bills add up, and money stress can make sleep and anxiety worse. For many people, that cycle is the hardest part.
Can You Sue for PTSD After a Dog Bite in Massachusetts?
In many cases, you may be able to. Massachusetts follows a strict liability rule for dog injuries. Under M.G.L. c. 140, § 155, if a dog does “any damage to either the body or property of any person,” the owner or keeper is liable. If the owner or keeper is a minor, liability falls on the parent or guardian.
What does that mean for you? Generally, you don’t have to prove the owner was careless or that the dog had bitten anyone before. The statute does include exceptions. An owner may not be liable if the injured person was committing a trespass or another tort, or was teasing, tormenting, or abusing the dog. For children under seven, the law presumes they weren’t doing any of those things, and the owner has to prove otherwise.
The statute covers damage a dog does, so a claim isn’t always limited to bites. Being knocked to the ground or hurt while separating dogs may also qualify, depending on the facts.
If your dog was attacked, Massachusetts treats your pet as property, so vet bills may be part of a claim. However, the Appeals Court declined to allow emotional distress damages for harm to an animal in Krasnecky v. Meffen (2002). Your own physical and emotional injuries are what a claim focuses on.
Many dog bite claims are paid through the owner’s homeowner’s or renter’s insurance. Read our FAQ on who can be sued for dog bite injuries goes deeper on liability.
Suing for Damages Because of PTSD From a Dog Bite
You can sue for the emotional trauma, such as PTSD, that results from a dog bite. While the courts generally recognize that PTSD can result from traumatic events, such as dog bites, you may need to provide documentation from a medical professional or testimony from an expert witness to prove your case.
Damages Dog Bite Victims Can Recover
Every case is different, but a Massachusetts dog bite claim may include:
- Medical bills, from the ER visit to follow-up care and surgery
- Mental health treatment, such as therapy or counseling
- Lost wages
- Reduced earning ability, if your injuries or fear affect your work
- Pain and suffering, including emotional distress like PTSD
- Scarring or disfigurement
- Vet bills (if your dog was attacked too) and other property damage
How Do You Prove PTSD After a Dog Bite?
A broken bone shows up on an X-ray. Anxiety doesn’t, so emotional harm usually takes more proof.
Massachusetts courts look for objective evidence. In Payton v. Abbott Labs (1982), the Supreme Judicial Court required physical harm shown by objective symptoms and supported by expert medical testimony for certain emotional distress claims. Later, in Sullivan v. Boston Gas Co. (1993), the court recognized symptoms like headaches, sleeplessness, stomach problems, and physical symptoms of PTSD.
Helpful evidence may include:
- A diagnosis and treatment records from a licensed provider
- Records of physical symptoms, like sleep problems or headaches
- A journal of nightmares, panic, and places you now avoid
- Statements from family, friends, or coworkers who’ve seen the change
- Photos of your injuries and the scene
- Proof of missed work
Should You Report the Dog Attack?
We usually recommend it. Contact your local animal control officer or board of health. Under the Mass.gov rabies protocol, a dog that bites a person is placed in strict confinement for 10 days, often at the owner’s home. The report also creates an official record, which helps if the owner refuses to share their information.
Some people hesitate because they worry the dog will be put down. Under M.G.L. c. 140, § 157, anyone may file a written complaint about a nuisance or dangerous dog. A local hearing authority then decides what happens. Possible orders include restraint, muzzling, secure confinement, or liability insurance. Euthanasia is one option in serious cases, not an automatic outcome.
