Common Dog Bite Injuries and Treatment: From Scars to Infections
Dog bites are a widespread and often underestimated source of injury in the United States, with profound physical, emotional, and financial consequences for dog bite victims. According to the Centers for Disease Control and Prevention (CDC), approximately 4.5 million dog bites occur annually nationwide, leading to around 800,000 individuals requiring medical attention, including hospitalizations for severe bite injuries.
In Arizona, the issue is particularly acute due to high pet ownership rates—estimated at over 1.5 million dogs—and the state’s pet-friendly lifestyle with numerous dog parks, hiking trails, and suburban neighborhoods. The Arizona Department of Health Services (ADHS) reports about 5,000 dog bite incidents each year, with more than 1,200 in Maricopa County (Phoenix area) necessitating emergency room visits. This figure reflects a steady increase of 7% from 2023, driven by population growth, post-pandemic pet adoptions, and warmer weather that encourages outdoor activities.
Children make up nearly 50% of dog bite victims nationally, often suffering facial injuries that can lead to lifelong disfigurement or traumatic brain injury. Adults, especially the elderly or those with weakened immune systems, face higher risks of complications like infections. The financial toll is significant: U.S. insurers paid out approximately $1.57 billion in dog bite-related claims in 2024, with average payouts exceeding $69,000 per claim, covering medical treatment, surgeries, lost wages, and more.
As a personal injury firm with an experienced dog bite lawyer team that handles animal attack cases, Accident Law Group has helped numerous dog bite victims in Phoenix and across Arizona understand the claims process. This guide explores common dog bite injuries, immediate and long-term treatment options, potential complications, Arizona-specific statistics, legal considerations for dog bite claims, prevention strategies, and support resources.

Types of Dog Bite Injuries: A Detailed Breakdown
Dog bite injuries vary based on the dog’s size, breed, jaw strength, and the victim’s age or health. The American College of Emergency Physicians classifies them into categories, each carrying unique risks that can strengthen a dog bite case under Arizona’s strict liability laws (ARS 11-1025).
- Puncture Wounds: The most common dog bite injury, accounting for about 40% of cases. These deep, narrow puncture wounds from dogs’ teeth can damage underlying tissues, muscles, or bones and often trap bacteria, leading to serious infection.
- Lacerations and Tears: Making up around 25% of dog bite wounds, these ragged cuts from shaking or clawing cause heavy bleeding and are highly prone to scarring, especially on the face or hands.
- Abrasions and Bruises: Surface-level soft tissue scrapes or contusions that may seem minor but can become infected or mask more serious damage, including broken bones from falls.
- Crush and Avulsion Injuries: Devastating bite injuries where powerful jaws compress or tear away tissue, often requiring immediate surgery. These are more common with larger dogs.
- Bone Fractures and Nerve Damage: In 10–15% of severe dog attacks, broken bones or severed nerves lead to chronic pain, loss of function, and the need for extensive rehabilitation.
- Facial and Head Injuries: Predominant in child dog bite victims (over 60% of pediatric cases), these can include eye damage, ear trauma, or scalp lacerations, resulting in permanent disfigurement, nerve damage, or traumatic brain injury.
Detailed documentation of these common injuries through medical records helps show what the injury involved.

Immediate and Long-Term Treatment for Dog Bite Injuries
Treatment must be swift to prevent complications, with protocols from the World Health Organization (WHO) and CDC emphasizing infection control.
- Immediate First Aid: Wash the wound with soap and water for at least 15 minutes to reduce bacterial load (dogs’ mouths harbor over 60 species, per a Journal of Clinical Microbiology study). Apply pressure to stop bleeding, elevate the area, and cover with a clean bandage. Avoid closing deep wounds yourself, as this traps bacteria.
- Medical Evaluation and Initial Care: Seek ER care within hours, especially for punctures or if the dog is unknown (rabies risk). Doctors will clean (debride) the wound, check whether a tetanus booster is needed, and prescribe antibiotics like amoxicillin-clavulanate for high-risk bites (face, hands, or immunocompromised patients).
- Rabies Prophylaxis: If the dog’s status is unknown, post-exposure prophylaxis (PEP) involves human rabies immune globulin (HRIG) and a vaccine series over 14 days. Arizona has low rabies incidence (mostly in bats/skunks), but ADHS mandates reporting for quarantine—failure can complicate claims.
- Surgical Interventions: For lacerations or avulsions, stitches or skin grafts may be required within 6-8 hours. Crush injuries might need orthopedic fixation or vascular repair, with costs soaring to $10,000+.
- Long-Term Treatment and Rehabilitation: Scars may require laser therapy or plastic surgery (ASPS reports 28,000 procedures in 2024). Nerve damage calls for physical therapy or pain management, while infections like cellulitis demand IV antibiotics and hospitalization (average stay 3-5 days). Emotional care via counseling addresses PTSD, common in 30% of victims per a Psychology Today review.

Complications Arising from Dog Bite Injuries
Even with prompt treatment, complications occur in 10-20% of cases, per ACEP.
- Bacterial Infections: The most common (up to 50% untreated), including Pasteurella, Staphylococcus, and Streptococcus, leading to abscesses or cellulitis. Severe cases progress to sepsis, with mortality rates of 20% if hospitalized.
- Scarring and Disfigurement: Keloid or hypertrophic scars affect 15% of victims, requiring multiple surgeries costing $5,000 each.
- Nerve Damage and Functional Loss: Leading to numbness, weakness, or chronic pain syndromes like complex regional pain syndrome (CRPS), necessitating ongoing therapy.
- Emotional and Psychological Trauma: Anxiety, phobias, or PTSD, especially in children, with 25% needing counseling per CDC.
- Rare but Severe Outcomes: Osteomyelitis (bone infection) or amputations in 1% of extreme cases, and rabies, which is fatal once symptoms appear.
