Dog Bite Infection Claims

Why Dog Bite Infections Are More Dangerous Than Most People Realize

A dog's mouth harbors over 600 species of bacteria. When a dog's teeth puncture human skin, these bacteria are driven deep into tissue layers where they can multiply rapidly in the warm, moist environment beneath the skin's surface. Studies show that approximately 15 to 20 percent of all dog bite wounds become infected, with puncture wounds carrying an even higher risk because the small entry point seals over the bacteria, trapping it inside the body.

For Michigan dog bite victims, infections represent both a serious medical emergency and a significant factor in the value of a personal injury claim. An infected dog bite typically requires far more extensive medical treatment, causes prolonged pain and disability, and may result in permanent complications that dramatically increase the compensation a victim deserves.

Pasteurella: The Most Common Dog Bite Infection

Pasteurella multocida is present in the mouths of 50 to 80 percent of dogs and is the most frequently identified bacterium in infected dog bite wounds. Pasteurella infections typically develop rapidly, often within 24 hours of the bite. Symptoms include intense redness and swelling at the bite site, warmth radiating from the wound, discharge of pus or cloudy fluid, and significant pain that worsens rather than improves over time.

While pasteurella infections usually respond to antibiotic treatment when caught early, delayed treatment can lead to serious complications including cellulitis (spreading skin infection), osteomyelitis (bone infection), septic arthritis (joint infection), and in severe cases, bacteremia where the bacteria enters the bloodstream. Patients with compromised immune systems, diabetes, liver disease, or those taking immunosuppressive medications face heightened risks.

MRSA and Antibiotic-Resistant Infections

Methicillin-resistant Staphylococcus aureus (MRSA) represents one of the most concerning complications of dog bite wounds. While MRSA is not commonly found in dog saliva, it can be introduced when the bite wound becomes contaminated from the victim's own skin flora or from environmental sources during the healing process. MRSA infections are particularly dangerous because they resist standard antibiotic treatments.

MRSA infections from dog bites may require IV antibiotics, surgical drainage of abscesses, extended hospitalization, and in severe cases, multiple surgeries to remove infected tissue. The treatment costs for MRSA infections frequently reach tens of thousands of dollars, and the recovery period can stretch for weeks or months. Victims may develop recurring infections that flare up months or even years after the original bite.

Capnocytophaga: A Rare but Devastating Infection

Capnocytophaga canimorsus is a bacterium commonly found in dog saliva that rarely causes infection in healthy individuals but can be catastrophic for people with weakened immune systems, those without a spleen, heavy alcohol users, and individuals with liver disease. When capnocytophaga infection takes hold, it can progress to sepsis, gangrene, and organ failure with alarming speed.

Reported cases of capnocytophaga infection have resulted in amputation of fingers, hands, or limbs due to gangrene; kidney failure requiring dialysis; heart attacks triggered by the systemic infection; and death in approximately 30 percent of cases where the infection reaches the bloodstream. Although rare, capnocytophaga infections underscore why every dog bite victim should monitor their wound carefully and seek immediate medical attention at the first sign of infection.

Rabies: The Most Feared Dog Bite Disease

Rabies remains the most feared potential consequence of any animal bite. While rabies in domestic dogs is rare in Michigan due to widespread vaccination programs, it is not impossible. Stray dogs, unvaccinated animals, and dogs that have had contact with wildlife such as raccoons, bats, or skunks may carry the rabies virus.

Rabies is nearly 100 percent fatal once symptoms appear, making post-exposure prophylaxis (PEP) critical for anyone bitten by a dog whose vaccination status cannot be confirmed. PEP involves a series of rabies immunoglobulin injections and vaccine doses administered over a 14-day period. The cost of rabies PEP treatment frequently exceeds $10,000 and is a fully compensable medical expense in a dog bite claim.

Michigan law requires a 10-day quarantine observation period for dogs that bite humans. If the dog remains healthy during this period, rabies transmission is ruled out. However, if the dog cannot be located, is a stray, or dies during observation, the bite victim must undergo PEP treatment as a precaution.

Sepsis: When Infection Becomes Life-Threatening

Sepsis occurs when the body's response to infection becomes dysregulated, triggering widespread inflammation that can damage multiple organ systems simultaneously. Any dog bite infection that is not properly treated can progress to sepsis, which remains one of the leading causes of death in hospitals nationwide.

Warning signs that a dog bite infection may be progressing to sepsis include high fever or abnormally low body temperature, rapid heart rate, rapid breathing, confusion or disorientation, extreme pain or discomfort, and clammy or sweaty skin. Sepsis requires immediate emergency medical treatment including IV antibiotics, fluids, and potentially vasopressors to maintain blood pressure. Septic shock carries a mortality rate of approximately 40 percent.

Delayed Symptoms and Why Timing Matters

One of the most dangerous aspects of dog bite infections is that symptoms may not appear for 24 to 72 hours after the bite, and some infections take even longer to manifest. Victims who feel fine immediately after a bite may dismiss the injury as minor, only to develop a serious infection days later. Capnocytophaga infections, for example, can take up to 14 days to produce symptoms.

This delayed onset creates both medical and legal issues. Medically, delayed treatment allows the infection to spread deeper into tissue and potentially into the bloodstream. Legally, insurance companies sometimes argue that the infection was caused by something other than the dog bite if there was a gap between the bite and the onset of symptoms. Thorough medical documentation establishing the timeline is essential for protecting your claim.

How Infections Increase Your Claim Value

A dog bite that becomes infected typically results in significantly higher compensation than an uncomplicated bite wound. Infections increase claim value through multiple categories of damages:

Additional medical expenses: Infected bites often require emergency room visits, hospitalization, IV antibiotics, surgical debridement (removal of infected tissue), wound care supplies, follow-up appointments, and sometimes reconstructive surgery. These costs can add tens of thousands of dollars to your medical bills.

Extended lost wages: While a simple dog bite might keep you out of work for a few days, an infected wound can prevent you from working for weeks or months. If you develop sepsis or require amputation, you may be permanently unable to return to your previous occupation.

Increased pain and suffering: Infections cause prolonged, intense pain that far exceeds the pain of the initial bite. The anxiety and fear associated with a life-threatening infection, multiple surgeries, and uncertain outcomes are compensable as emotional distress.

Permanent scarring and disfigurement: Infected wounds heal poorly and often leave more significant scars than clean wounds. Surgical debridement and skin grafting create additional scarring. These permanent changes to your appearance increase the non-economic damages in your claim.

Future medical care: Some infections cause permanent damage that requires ongoing medical treatment. Osteomyelitis may require years of monitoring. Joint infections can cause permanent arthritis. Amputations require prosthetics and lifetime follow-up care.

What to Do If Your Dog Bite Becomes Infected

If you notice signs of infection after a dog bite, seek medical attention immediately. Do not wait to see if symptoms improve on their own. Document your symptoms with photographs showing the progression of redness, swelling, and any discharge. Keep a written log of your symptoms, pain levels, and any fever readings.

Preserve all medical records, pharmacy receipts, and documentation of time missed from work. If you have not already reported the bite to animal control, do so immediately so the dog's vaccination records can be obtained and quarantine can be initiated if necessary.

Contact a personal injury attorney as soon as possible. Under Michigan's dog bite strict liability statute, the dog's owner is responsible for all damages caused by the bite, including complications from infections. An experienced attorney can ensure that the full scope of your infection-related damages is documented and pursued in your claim.
