Dog bites can cause serious physical injuries, but many victims are unaware of the medical risks that may develop after the initial wound is treated. Even a small puncture can expose you to harmful bacteria, viruses, and other pathogens. Without proper medical attention, infections and complications can become severe.
If you or a loved one has been bitten by a dog, understanding the diseases to watch for can help you seek prompt treatment and protect your health. Below are some of the most common and serious diseases associated with dog bites.
1. Rabies
Rabies is one of the most well-known diseases linked to animal bites. It is a viral infection that attacks the central nervous system and is almost always fatal once symptoms appear.
Although rabies is relatively rare in vaccinated domestic dogs in the United States, the risk still exists—especially if the dog’s vaccination status is unknown or the animal was acting strangely.
Symptoms of rabies may include:
- Fever
- Headache
- Muscle weakness
- Confusion or agitation
- Difficulty swallowing
- Hallucinations
If rabies exposure is suspected, immediate medical treatment is critical. Post-exposure prophylaxis (PEP) can prevent the virus from progressing when administered promptly.
2. Capnocytophaga Infection
Capnocytophaga is a type of bacteria commonly found in dogs’ mouths. While it does not typically cause illness in healthy individuals, it can lead to severe infections in some people, particularly those with weakened immune systems, liver disease, or those who have had their spleen removed.
Warning signs include:
- Redness, swelling, or blisters around the wound
- Fever
- Vomiting or diarrhea
- Severe muscle or joint pain
- Confusion
Prompt antibiotic treatment is essential to prevent serious complications.
3. Pasteurella Infection
Pasteurella bacteria are frequently present in dog bite wounds. Infection can develop within 24 hours of the bite.
Common symptoms are:
- Pain and swelling at the wound site
- Redness and warmth
- Pus or discharge
- Swollen lymph nodes
If untreated, the infection can spread to nearby joints or bones, potentially causing long-term damage. Early antibiotic treatment usually resolves the infection effectively.
4. Tetanus
Tetanus is caused by bacteria found in soil, dust, and animal feces. While not specific to dog bites, any deep puncture wound can introduce tetanus bacteria into the body.
Tetanus affects the nervous system and can cause severe muscle stiffness and spasms.
Symptoms may include:
- Jaw cramping (lockjaw)
- Neck stiffness
- Difficulty swallowing
- Painful muscle spasms
Most people are protected through routine vaccination. However, if your tetanus shot is not up to date, a booster may be necessary after a dog bite.
5. Staph and MRSA Infections
Staphylococcus (staph) bacteria can enter the body through broken skin. In some cases, methicillin-resistant Staphylococcus aureus (MRSA) may develop, which is resistant to certain antibiotics.
These infections can spread quickly and require medical intervention.
Signs to watch for:
- Increasing redness or swelling
- Warmth around the wound
- Fever
- Drainage or abscess formation
Early treatment reduces the risk of the infection spreading.
6. Sepsis
Sepsis is not a specific bacteria or virus but a severe and potentially life-threatening response to infection. It can occur if bacteria from a dog bite enter the bloodstream.
Symptoms of sepsis include:
- High or low body temperature
- Rapid heart rate
- Rapid breathing
- Extreme pain or discomfort
- Confusion or disorientation
Sepsis is a medical emergency and requires immediate hospital treatment.
When to Seek Medical Attention
You should seek medical care immediately if:
- The bite breaks the skin
- The wound is deep or bleeding heavily
- The dog’s vaccination status is unknown
- You notice signs of infection
- You have not had a recent tetanus shot
Even minor bites should be evaluated by a medical professional to reduce the risk of complications.
