How long after a dog bite does infection set in?
After being bitten, most people who become ill will show symptoms within 3 to 5 days, but this can range anywhere from 1 to 14 days. Most
According to the Academy of Pediatrics, infection occurs in about 10 to 15 percent of dog bites. Dog bites that go untreated without proper cleaning and medical care are at increased risk of developing infections, which can be passed to another through bacteria.
In general, most experts recommend seeking medical care within 24 hours after you've been bitten—especially if the bite has broken the skin. Dog bites can cause medical problems that aren't immediately obvious, such as rabies.
Dog bite wounds that have become infected are often red, painful, and swollen. Fluid or pus may ooze from the wound. Tenderness and tingling of the bite wound are also common signs of infection.
- Increased pain, swelling, warmth, or redness near the wound.
- Red streaks leading from the wound.
- Pus draining from the wound.
- A fever.
Antibiotic prophylaxis commonly is recommended for moderate to severe wounds of the face, hands (bites tend to involve the dominant hand), feet or genital area. Bites involving tendon, bone or joints and bites resulting in devitalized tissue generally are treated with antibiotic prophylaxis.
Overall, only a fifth of dog bites become infected, compared with 36% of hand bites,13 and loss of function can result from infection.
Blisters around the bite wound within hours of the bite. Redness, swelling, draining pus, or pain at the bite wound. Fever. Diarrhea and/or stomach pain.
Dogs, cats, ferrets, and livestock such as horses, cattle, goats and sheep should be confined and observed for 10 days following a bite, to rule out rabies risk. There is no such option for wild animals that bite humans; these bites are handled on a case-by-case basis following consultation with MDH.
Level Two:
At a level two bite, a dog's teeth will make contact with a person's skin and leave some redness or light bruising but does not break the skin.
What is the most common infection from a dog bite?
The most common pathogens in dog bites are Pasteurella spp. (both Pasteurella multocida and Pasteurella canis), Staphylococcus and Streptococcus spp., and the fastidious Gram-negative rod Capnocytophaga canimorsus (previously known as the CDC and Prevention Group Dysgonic Fermenter-2).
Level 1: No skin-contact by teeth – can be exuberant obnoxious behavior or aggression. Level 2: Skin contact made but no punctures. There may be small lacerations. Level 3: One-four shallow punctures from a single bite and potentially small lacerations from pulling the biting dog or victim body part away.

Seek prompt medical attention from a physician, even if the bite is mild and the skin is barely broken. Immediate vaccination can prevent rabies from developing.
q 14: do you have to take vaccination against rabies if a vaccinated dog bites you? No, not if the dog is properly vaccinated against rabies and the efficacy of the vaccine is confirmed by laboratory evidence. Otherwise an appropriate post-exposure prophylaxis (PEP) should be given.
If the bite is not bleeding severely, wash the wound thoroughly with mild soap and running water for 3 to 5 minutes. Then cover the bite with antibiotic ointment and a clean dressing. An animal bite may not appear to be life-threatening, but if left untreated the bite can lead to a serious infection.
Even if you're able to clean up the wound yourself, you should still visit a doctor immediately after being bitten. Tetanus shots may need to be administered within 48 hours to be most effective. The doctor may discuss whether you need other treatment which may include antibiotics and, in some cases, rabies shots.
Treat the dog bite
For small wounds, apply an antibiotic cream such as Neosporin or Bacitracin to the injury and wrap it in a clean bandage. For deep wounds, apply pressure using a clean, dry cloth until the bleeding stops and then bandage the injury.
The Centers for Disease Control and Prevention (CDC) notes that one serious concern after getting bit by a dog is the risk of infection. By neglecting to seek medical care, a small infection can quickly escalate into a life-altering condition. You should always follow your doctor's orders after getting bit.
The most common symptoms of infection from animal bites are redness, pain, swelling, and inflammation at the site of the bite. You should seek immediate medical treatment if any of these symptoms continue for more than 24 hours. Other symptoms of infection include: pus or fluid oozing from the wound.
But you should err on the side of caution — which means seeking medical attention — for all dog bites, especially ones that break the skin. You should definitely be evaluated by a medical provider if the wound is: Large or deep. On the head, face, neck, genitals, hands, or feet.
Is swelling normal after a dog bite?
Yes, swelling is normal after a dog bite, but increased swelling after the initial first aid can be a sign of infection. Dog bites may be dirty wounds that are prone to infection.
So is swelling normal after a dog bite? Swelling, redness, or pain that lasts more than 24 hours from an animal bite could be a sign of an infection that could lead to more serious complications. See a qualified medical professional as soon as possible to get the bite checked out if pus is draining from your wound.
Tetanus immunization — Tetanus is a serious, potentially life-threatening infection that can be transmitted by an animal or human bite. Adults who are bitten should receive a tetanus vaccine (called a tetanus toxoid vaccine) if the most recent tetanus vaccine was greater than 5 years previously.
Most of these signs are obvious to even an untrained observer, but within a short period of time, usually within 3 to 5 days, the virus has caused enough damage to the brain that the animal begins to show unmistakable signs of rabies.
Symptoms. The incubation period for rabies is typically 2–3 months but may vary from 1 week to 1 year, depending on factors such as the location of virus entry and the viral load.
If you have been bitten by a dog recently, then there are some dietary restrictions that you must follow. In India, various studies have been done and the results have found out that spicy food, potatoes, tomatoes, coriander, dhal, and meat should be avoided completely during Dog Bites.
Most scientific studies indicate that it is very possible to rehabilitate a dog after they bite another dog or person.
Level 3. One to four punctures from a single bite with no puncture deeper than half the length of the dog's canine teeth. Maybe lacerations in a single direction, caused by victim pulling hand away, owner pulling dog away, or gravity (little dog jumps, bites and drops to floor).
- LEVEL 1—AGGRESSIVE BUT NO SKIN CONTACT. ...
- LEVEL 2—TEETH MAKE CONTACT, BUT DO NOT BREAK SKIN. ...
- LEVEL 3—A SINGLE BITE WITH SHALLOW WOUNDS. ...
- LEVEL 4—A SINGLE BITE WITH DEEP WOUNDS. ...
- LEVEL 5—MULTIPLE BITES WITH DEEP WOUNDS. ...
- LEVEL 6—DEATH OF THE VICTIM AND/OR FLESH CONSUMED.
What will your doctor do? Your doctor will want to know more about the dog that bit you and how it happened. They will also likely clean the wound again, apply antibiotic ointment and prescribe antibiotics, such as Augmentin, if there's an infection concern.
Should I worry about a Level 2 dog bite?
Level 2 Dog Bite:
You might see redness and light bruising. The level 2 dog bite is concerning, even though it has not yet broken the skin. For level 2 dog bite treatment, you should see a doctor to reduce your risk of bacterial infection.
Level 2 Bite - Skin-contact by teeth but no skin-puncture. This doggie is a little more serious about his aggression. He is willing to take it a step further to let you know that he doesn't want you there. Level 1 and 2 bites make up 99% or more of dog bite incidents.
- clean the wound and remove any damaged tissue.
- prescribe a course of antibiotics to prevent infection.
- recommend specific treatment to prevent infections such as tetanus if you're felt to be at risk.
Although you can provide first aid for a dog bite at home, it's very important to see a doctor, especially if an unfamiliar dog bit you, the bite is deep, you can't stop the bleeding, or there are any signs of infection (redness, swelling, warmth, pus).
In most cases, a dog bite will heal within about 10 to 14 days of the attack. However, serious dog bites may take longer to heal. If your dog bite is severe enough, you may require medical treatment, including stitches or even surgery, to fully heal.
Amoxicillin and clavulanate (Augmentin)
Amoxicillin and clavulanate is first-line therapy for the prophylactic treatment of dog, human, and cat bites (see Medication Summary above). It is also indicated for skin and skin structure infections caused by beta-lactamase–producing strains of Staphylococcus aureus.
Left untreated, it can lead to death within a few days of infection. Seek immediate medical attention if you've been bitten by a dog and you aren't sure of their vaccination history or know that they're not up-to-date on their rabies vaccinations.
Animal bites must immediately receive medical attention and be reported to the proper authorities, who will supervise the response. Information about the incident should be transferred with the animal and its paperwork at every point along the path to and from an Emergency Animal Care Center.
Apply an antibiotic ointment
The most effective are Bacitracin and Neosporin. Make sure you sterilize your hands with rubbing alcohol before putting antibiotic cream on the wound.
- Jaw cramping.
- Sudden, involuntary muscle spasms — often in the stomach.
- Painful muscle stiffness all over the body.
- Trouble swallowing.
- Seizures (jerking or staring)
- Headache.
- Fever and sweating.
- Changes in blood pressure and heart rate.
What happens if you don t get a tetanus shot within 48 hours?
If left untreated, a tetanus infection can be life threatening to some people. There isn't a known cure for tetanus and treating the infection is mostly managing how the infection is affecting the patient until it goes away.
Any dog bite can become life-threatening if it develops an infection. All open wounds caused by dogs require medical treatment to clean them out and prevent infection. Of course, when there is heavy bleeding, or the wound affects more than just the skin, it is imperative to get emergency medical care immediately.
Animal bites that don't break the skin are not at risk for infection. Scrapes or scratches that just graze the skin's surface have a minimal risk of infection. Cuts or lacerations have a higher risk of infection.
Dog bites often leave deep and jagged wounds that must be stitched. Regardless of what kind of animal bit them, people should seek ER care so that any embedded debris can be removed and deep and shredded skin can be stitched up properly.
But you should err on the side of caution — which means seeking medical attention — for all dog bites, especially ones that break the skin. You should definitely be evaluated by a medical provider if the wound is: Large or deep. On the head, face, neck, genitals, hands, or feet.
No matter what, make sure you see a doctor within eight hours of a dog bite, he says. Waiting longer raises your infection risk. If you have diabetes or are immunocompromised, your infection risk is even greater.
