What Are the Most Common Dog Bite Injuries?

Every year, millions of Americans are bitten by dogs. Some bites leave only a small scratch. Others cause life-altering injuries — broken bones, nerve damage, permanent scarring, and even psychological trauma that lingers long after the wound has healed.

If you or someone you love has been attacked by a dog, understanding the full scope of your injuries is critical — not just for medical treatment, but for building a strong legal claim. The type and severity of injury directly impacts how much compensation you may be entitled to receive.

This guide walks you through the most common dog bite injuries, how they're treated, what the law says, and what steps you need to take to protect your health and your legal rights.

Step-by-Step: What Happens to Your Body During a Dog Bite Attack

Dog bite injuries aren't always as straightforward as they look. The damage that happens beneath the skin is often far more serious than the surface wound suggests. Here's how a dog bite typically injures the human body:

1. Initial Impact & Puncture: A dog's jaw exerts between 150 and 300 pounds per square inch of pressure. The teeth punch deep into skin, muscle, and sometimes bone, creating puncture wounds that are difficult to clean and prone to infection.
2. Tissue Tearing: Dogs instinctively shake their heads when biting, which causes the wound to tear outward into a laceration. This dramatically increases the size and severity of the injury.
3. Bacterial Contamination: Dog saliva contains hundreds of bacterial strains. Within hours, bacteria like Pasteurella multocida, Capnocytophaga, and MRSA can begin multiplying in the wound.
4. Nerve & Vascular Disruption: Deep bites — especially on the hands, face, or neck — can sever or compress nerves and blood vessels, causing numbness, loss of function, or dangerous bleeding.
5. Bone Fractures or Crushing: In attacks involving large breeds or children, the force can fracture small bones, particularly in the hands, wrists, and feet.
6. Psychological Response: Even after physical wounds heal, victims frequently experience post-traumatic stress disorder (PTSD), anxiety, and a lasting fear of dogs that disrupts daily life.

The Most Common Dog Bite Injuries Explained

1. Puncture Wounds and Lacerations

These are the most immediately visible injuries. Puncture wounds occur when a dog's tooth pierces the skin without a large tear. Despite appearing small on the surface, puncture wounds are deceptively dangerous — they create a narrow, deep channel that traps bacteria and is difficult to irrigate.

Lacerations are longer cuts caused when a dog bites and pulls. They often require stitches, surgical staples, or in severe cases, skin grafting. Deep lacerations can damage the underlying fascia, muscle tissue, and connective structures.

Victims in cities like Los Angeles and San Diego frequently report these types of wounds from off-leash dog encounters in parks and residential neighborhoods.

2. Infections — One of the Deadliest Complications

Dog bite infections are among the most underestimated risks after an attack. Because puncture wounds seal over quickly, bacteria become trapped and multiply. The most serious infections include:

• Pasteurella: Found in up to 50% of infected dog bites; causes rapid swelling, redness, and intense pain within 24 hours.
• Capnocytophaga canimorsus: A rare but potentially fatal bacteria; at highest risk are people with weakened immune systems.
• MRSA (Methicillin-Resistant Staphylococcus aureus): An antibiotic-resistant infection that can spread to bone and bloodstream.
• Rabies: Though rare in the U.S., it is universally fatal if left untreated. The CDC recommends post-exposure prophylaxis if the biting dog cannot be confirmed vaccinated.
• Tetanus: Particularly a concern in deep puncture wounds in individuals whose vaccinations are not up to date.

Infections can turn a seemingly minor bite into a weeks-long medical ordeal requiring IV antibiotics, hospitalization, or surgery. This significantly increases both medical costs and the value of a legal claim.

3. Nerve and Tendon Damage

Nerve damage is one of the most life-altering consequences of a serious dog bite. The hands and fingers are especially vulnerable — they contain intricate networks of nerves and tendons that control grip, sensation, and fine motor movements.

When a dog's teeth cut through these structures, victims may experience:

• Permanent numbness or tingling in fingers or limbs
• Loss of grip strength
• Inability to perform fine motor tasks (writing, typing, playing instruments)
• Chronic pain or hypersensitivity along the nerve pathway

Tendon damage often requires microsurgical repair and months of physical therapy. Even then, full recovery is not guaranteed. These injuries are common in workers who reach out to restrain a dog — a reflex that places the hand directly in the bite zone.

Residents in Ohio and Indiana report some of the highest rates of dog bite hospitalizations in the Midwest, and nerve/tendon injuries feature prominently in these claims.

4. Fractures and Crush Injuries

Large breed dogs — including Pit Bulls, Rottweilers, German Shepherds, and Mastiffs — can exert enough jaw pressure to crack or shatter small bones. Fractures most commonly occur in:

• The fingers and metacarpal bones of the hand
• Wrist bones (particularly during defensive holds)
• Facial bones — orbital (eye socket), nasal, and cheekbone fractures
• Lower leg bones in children knocked to the ground

Crush injuries are particularly serious. They don't just break bones — they damage blood vessels, nerves, and muscle simultaneously, often leading to complications like compartment syndrome, where swelling causes dangerous pressure buildup inside the muscle compartment.

5. Facial Injuries and Permanent Scarring

Children are especially vulnerable to facial dog bite injuries because their faces are at the same height as most dogs' mouths. According to data from the American Academy of Plastic Surgeons, the face is the most commonly bitten area in children under the age of ten.

Facial dog bite injuries can include:

• Lacerations to the cheeks, nose, lips, and forehead
• Eyelid and periorbital injuries that threaten vision
• Ear avulsion (partial or full tearing of the ear)
• Permanent disfiguring scars requiring reconstructive plastic surgery

Scarring carries significant economic and emotional weight in a legal claim. Visible facial scars, especially in children, can command substantial compensation for disfigurement, lost quality of life, and future medical costs related to revision surgery.

6. Eye Injuries

Dog bites to the face can damage the eye or its surrounding structures. Common eye injuries from dog attacks include corneal scratches, orbital fractures, retinal detachment, and in severe cases, permanent vision loss. These injuries require immediate ophthalmological attention and often extensive treatment.

7. Soft Tissue Injuries and Avulsions

An avulsion occurs when a dog's bite tears away a section of skin and tissue entirely. This type of injury is particularly traumatic, often requiring reconstructive surgery and skin grafting. Soft tissue injuries affecting deep muscle layers may need weeks of wound care to avoid necrosis (tissue death).

8. Psychological Injuries — Often Overlooked but Legally Compensable

Physical wounds heal. Psychological trauma often doesn't — at least not without professional help. Post-traumatic stress disorder (PTSD) following a dog attack is well-documented in medical literature, particularly in children.

Psychological injuries from dog bites can include:

• Nightmares and intrusive memories of the attack
• Panic attacks when near dogs or in outdoor spaces
• Significant anxiety and fear that limits daily activities
• Depression from disfigurement or disability
• Behavioral regression in children

Courts across the country increasingly recognize psychological harm as a legitimate component of dog bite claims. Pain and suffering — which encompasses emotional distress — is often the largest line item in a settlement.

What to Do After a Dog Bite — A Step-by-Step Guide

1. Seek Medical Attention Immediately — Even small puncture wounds can become infected rapidly. Get treated within hours, not days.
2. Identify the Dog and Owner — Get the dog owner's name, contact information, and proof of rabies vaccination if available.
3. Document Your Injuries — Photograph the wound immediately, and again over the following days as it heals or worsens.
4. Report the Bite — File a report with your local animal control agency. This creates an official record and may prevent future attacks.
5. Gather Evidence — Witnesses, surveillance footage, medical records, and prior complaints about the dog are all valuable. Read our guide on what evidence you need for a dog bite case.
6. Preserve Records — Keep all medical bills, prescription receipts, and records of missed work.
7. Consult a Legal Professional — Most dog bite lawyer consultations are free, and attorneys typically work on contingency — meaning you pay nothing unless you win.
