Dog bites can cause several serious bacterial infections, the most common being Pasteurella, Capnocytophaga, Staphylococcus, and Streptococcus. Rabies is rare but life-threatening if left untreated. Even a bite that looks minor can introduce bacteria deep into tissue, and infections can escalate quickly, especially in people with compromised immune systems, diabetes, or anyone who delays medical care.
Pasteurella is a bacterium found naturally in a dog’s mouth. It’s present in more than half of all infected dog bite wounds and moves fast. Symptoms typically appear within 12 to 24 hours of the bite: redness, swelling, and tenderness at the wound site, followed by drainage and increasing pain.
Left untreated, a localized Pasteurella infection can spread to surrounding tissue, lymph nodes, and joints. In severe cases, it progresses to osteomyelitis (bone infection), pneumonia, or meningitis. People with liver disease, diabetes, or other immune-compromising conditions face a higher risk of the infection becoming invasive.
This is one reason consulting a Las Vegas dog bite attorney matters early. Infection-related complications add medical costs, lost wages, and extended recovery time to your damages, and those need to be documented while still active.
Capnocytophaga is a bacterium that lives in the mouths of healthy dogs. Most people who are bitten never develop an infection. But in people with weakened immune systems, those who have had their spleen removed, or those with certain chronic conditions, Capnocytophaga can cause a severe and rapid illness.
According to the CDC’s guidance on Capnocytophaga, symptoms typically appear within 1 to 14 days of a bite and can include blisters around the wound, fever, confusion, muscle pain, and nausea. The infection can enter the bloodstream and lead to sepsis, endocarditis, meningitis, or organ failure. In serious cases, it has resulted in limb amputation and death.
If you have any risk factors, see a doctor immediately after a bite, regardless of how minor the wound appears.
Methicillin-resistant Staphylococcus aureus (MRSA) and other staph bacteria can enter through a dog bite just as they would through any open wound. MRSA is particularly difficult to treat because it resists standard antibiotics. Streptococcal bacteria are also commonly cultured from dog bite wounds.
Signs of a staph or strep infection include increasing warmth, redness, swelling, pus, and red streaks extending from the wound. Red streaking along the arm or leg is a warning sign that infection is spreading through the lymphatic system. That requires emergency medical attention.
The Mayo Clinic recommends washing any animal bite thoroughly with soap and water immediately, then seeking medical evaluation, especially for deep puncture wounds or wounds near joints.
Rabies from domestic dogs in the United States is rare, but it cannot be dismissed. According to the Mayo Clinic, once symptoms develop, rabies is almost always fatal. Post-exposure treatment is highly effective when started immediately, which is why timing matters.
In Clark County, Animal Protection Services quarantines any biting animal for 10 days to observe for signs of rabies. If the dog cannot be located or identified, your doctor will typically recommend beginning post-exposure prophylaxis. Do not wait for symptoms before seeking evaluation.
Under NRS 202.500, an owner whose dog bites without provocation may face civil and criminal liability, and a dog with a bite history may be classified as dangerous. The rabies vaccination status of the dog is directly relevant to both your medical treatment decisions and your legal claim.
Infection significantly affects the value of your case. Medical bills for hospitalization, IV antibiotics, surgical debridement, and specialist visits all compound quickly once an infection escalates. Permanent scarring from tissue damage, nerve injury from deep puncture wounds, and psychological effects from a serious bite are all compensable damages under Nevada law.
Before photographing the dog and reporting the bite establishes the liability side of your claim, your medical records establish the damages side. The two tracks work together. An infection that required multiple hospitalizations or surgical treatment tells a very different damage story than a wound that healed with basic outpatient care.
Understanding how homeowner’s insurance applies to dog bites is also relevant here, since medical costs from a serious infection can quickly exceed standard policy limits of $100,000 to $300,000.
Workers bitten on the job, including postal workers, delivery drivers, home health aides, and utility workers, may have a workers’ compensation claim in addition to, or instead of, a personal injury claim against the dog owner. WC covers medical treatment and lost wages regardless of fault. Maintaining consistent treatment throughout recovery matters whether you’re pursuing a WC claim or a personal injury case.
