Dog bites can be traumatic and potentially life-threatening, with various types of wounds that can occur. Lacerations are a common type of dog bite wound, characterized by a jagged edge and often requiring stitches to close.
A deep puncture wound can be particularly concerning, as it can cause significant tissue damage and lead to infections. Infections can be serious, even life-threatening, if left untreated.
Some dog breeds are more prone to biting than others, with larger breeds like German Shepherds and Rottweilers being more likely to cause severe wounds. The force of a dog's bite can be immense, with some dogs able to exert a bite force of up to 700 pounds per square inch.

According to the CDC, more than 80% of dog bites do not require medical attention, but even minor injuries can develop complications if not properly treated.
Here are some of the most common types of dog bite injuries:
- Scrapes
- Bruises
- Rashes
More severe dog bites can lead to long-term issues such as scarring and loss of mobility, and may require surgery and skin grafting.
Minor Injuries
Minor injuries from dog bites are more common than you might think. They can include scrapes, bruises, and rashes.
These types of injuries may seem minor, but they can still develop complications. A wound that requires closing with staples or stitches can present a greater risk of infection.
Some common symptoms to watch out for include redness, swelling, pus, and increased pain around the wound. If you notice any of these symptoms, it's essential to seek medical attention right away.
Here are some examples of minor injuries from dog bites:
- Scrapes
- Bruises
- Rashes
Severe Injuries
Severe dog bites can lead to long-term issues of scarring and/or loss of mobility. The risk for complication rises with the number of bites and the areas in which those bites occur.
Deep-wound dog bites, like punctures and skin tears, often require surgery and skin grafting. This can result in tens of thousands of dollars in medical bills and years of recovery.
Severe dog bites can impact muscles, tendons, ligaments, and bones. This can have long-lasting consequences for the victim.
Some severe injuries from dog bites include bone fractures, torn ligaments, and avulsions. These injuries can result in not just an altered appearance but also impairment of functionality.
Here are some examples of severe injuries from dog bites:
- Bone fractures – especially on the facial bones or hands and feet
- Torn ligaments – often in the face, hands, and feet
- Avulsions – chunks of tissue being torn from the body, including all three layers of skin
- Amputations – removal of fingers, toes, arms, legs, and feet
- Nerve damage – leading to permanent pain and loss of muscle function
- Fatalities – although uncommon, severe dog attacks can be fatal, especially for children and the elderly
Common Infections
Dog bites can be serious business, and one of the biggest concerns is infection. The most common types of dog bite infections include staph and strep infections, which can cause fevers, joint swelling, and cellulitis. If you experience symptoms like pus-filled blisters, painful red skin, or fever after a dog bite, see a doctor immediately.

Staph and strep infections are serious conditions caused by staphylococcus or streptococcus bacteria. Symptoms can vary widely and include fevers, joint swelling, and cellulitis, depending on which part of the body the bacteria has invaded.
Pasteurella is another common type of bacteria found in dog bites. According to the CDC, Pasteurella is found in pet-bite injuries 75% of the time, representing a significant health risk. Symptoms of Pasteurella infections include redness and inflammation shortly after the biting incident, and can lead to more serious complications like osteomyelitis, septic arthritis, and pneumonia.
Here are some common dog bite infections and their symptoms:
- Staph and strep infections: fevers, joint swelling, cellulitis
- Pasteurella infections: redness and inflammation, osteomyelitis, septic arthritis, pneumonia
- Capnocytophaga infections: blisters around the bite wound, redness, swelling, pus, fever, abdominal pain, nausea, vomiting, and/or diarrhea, headache, confusion, muscle and joint pain
It's essential to seek medical attention immediately if you experience any of these symptoms after a dog bite.

To care for a dog bite injury at home, place a clean towel over the injury to stop any bleeding, try to keep the injured area elevated, wash the bite carefully with soap and water, apply a sterile bandage to the wound, and apply antibiotic ointment to the injury every day to prevent infection.
Here are some questions your doctor will ask to determine the best course of treatment:
- Do you know the owner of the dog?
- If so, is the dog up to date on all vaccinations, including rabies?
- Did the bite occur because the dog was provoked, or was the dog unprovoked?
- What health conditions do you have?
Your doctor will examine the injury to see whether the bite was deep enough to damage muscles, tendons, nerves, or bones, and may take measures to prevent infection, including prescribing antibiotics for seven to 14 days.
What to Do If
If you experience a severe allergic reaction, seek medical attention immediately.
Call 911 or your local emergency number if symptoms such as difficulty breathing, rapid heartbeat, or swelling of the face, lips, tongue, or throat occur.
Rinse your eyes with water if you get soap or shampoo in them, as this can help to remove the irritant.
Apply a cold compress to burns to reduce pain and promote healing.
If you suspect you have a concussion, stop all physical activity and rest for at least 24 hours.
Monitor your blood pressure regularly if you have hypertension, as uncontrolled high blood pressure can lead to serious complications.
