Dog Bite 101: The Ultimate Guide for Wound Infection Risks, Emergency Treatment & Prevention Tips for Dog Parents

dog bite
We call our pups man’s best friend, and in so many ways it’s true. But dogs are still animals, and sometimes they can accidentally bite us. The city of Alexandria, VA defines a dog bite as, “any contact by a dog that results in broken skin, including puncture, bite or scratch.” While most injuries are minor, about 1 in 5 times dog bites need a doctor’s care.
Our goal in this article is to provide you with information that can help you be better prepared for unexpected accidents. To accomplish this, we’ll examine:
Even the calmest, most friendly dog can bite under the right circumstances. Fortunately, most pups will only resort to biting when they feel threatened or provoked in some way.
Canines will usually signal before they lash out at someone. That’s why learning how to read dog body language can help you prevent unwanted accidents. Fido may be getting ready to bite if you notice him

If you notice these symptoms, contact your doctor immediately for treatment.

Treatment

If an unfamiliar dog bites you the first thing you want to do after making sure Fido is secured is to ask the owner about their pup’s vaccination history. It’s particularly important to know that the pooch is up-to-date on rabies vaccinations. Once you have that information, you can evaluate the wound and determine if you can take care of it yourself or you need medical attention.

Care for a Dog Bite at Home

Once you know that the pup is under control and won’t bite again you can attend to the wound.
Control bleeding – The first step is to control the bleeding.
Wash the wound – Once bleeding stops, gently cleanse the area with soap and warm water. It’s okay to wash the insides of the bite area. Be sure to rinse all soap residue to prevent future irritation.
Apply a dressing – Cover the wound with a dry, clean bandage or dressing.
Monitor the wound – Check the area as it heals to watch for signs of infection.

When Should I Seek Medical Attention For a Bite Wound?

In the case of an otherwise minor bite, you should seek medical care if:

What Will a Doctor Do To Treat a Dog Bite Injury?

Any time that a dog bite penetrates the skin there’s a risk of infection. Therefore, it’s wise to call or visit your doctor. When you go in, a health care professional will likely:

Antibiotics for treating dog bite infections

Infections are common following a dog bite because there’s bacteria in Fido’s mouth and saliva. Generally, the microbes associated with these injuries respond to antibiotic treatment with penicillins like amoxicillin.

Treatment for a penicillin-allergic patient

Adults that are allergic to penicillin and penicillin derivatives can be treated with cefuroxime or clindamycin and ciprofloxacin. For children, an acceptable alternative antibiotic course is cefuroxime or clindamycin and trimethoprim.

Complications

Whether the wound is minor or severe in nature, there are some possible complications that you need to know about:
When a dog bites you, you might get more than a skin wound. Canines can spread germs from bacteria and viruses in their mouths and saliva. According to the Center for Disease Control, up to 18% of dog bites may become infected. So what diseases can you get when a pup bites you?

Rabies

Rabies is probably the most serious disease that you can get from a dog. It comes from a virus that spreads through body fluids like saliva. The rabies virus attacks the brain and nervous tissue. Once a person shows signs of the disease, it is almost always fatal.
If you’re wondering, “Will I get rabies from a dog bite?” it is possible. The good news is that getting a rabies infection from a dog is rare in the United States. Most pups receive routine vaccinations. However, if there is any doubt, you can talk to your doctor about getting a rabies shot.

Capnocytophaga bacteria

This class of bacteria lives in dog’s mouths and is not dangerous to your pup. But it can be harmful to you. On rare occasion, the organism penetrates deep into a wound. For most people, this will cause a low-grade infection. However, individuals with a weak immune system may become severely ill.

Tetanus

Tetanus comes from the Clostridium tetani bacterium and is found in dirt and dust as well as dog’s mouths. Infection with this bacteria most commonly occurs with a puncture wound such as a dog bite. Untreated, it causes a rigid paralysis in the patient that can ultimately result in death.

Pasteurella bacteria

Pasteurella is the most common cause of dog bite infections. According the the CDC it accounts for over half of the cases. Usually, the bacteria causes a local infection with swelling and redness. If left untreated, however, it can spread to the lymph nodes and cause pneumonia or meningitis.

MSRA

Methicillin-resistant Staphylococcus aureus is a strain of bacteria that has a resistance to one class of antibiotics. Staphylococcus organisms exist on skin and in dog’s mouths. This strain is not terribly common, but it can lead to serious infections and illnesses if it gets in the bloodstream through a bite wound.

Zoonosis

A zoonoss or zoonotic disease is an infectious disease that animals are able to transmit to people. Under normal circumstances, dogs are a minimal zoonotic risk to humans. However, the chance of contracting an infection from Fido increases if someone has a weakened immune system, or if the offending organisms enter a person’s system through a dog bite.

Tips & Information for Parents

Dog Bite Prevention
Without training and supervision, most children don’t know how to act around dogs. In addition, a youngster’s behavior can trigger aggressive actions in canines.
Often toddlers and young kids don’t know how to read dog body language. What youngsters see as a bear hug or a playful tug can feel painful or threatening to Fido. He might express his pain or nervousness with his teeth. While there are no guarantees, taking some precautions around Fido can significantly reduce the chance of being bitten.

Effect of a Short Educational Intervention for Preschool Children

It’s important to talk with your preschool-aged children about how to treat a dog. Kids don’t automatically know about canine behavior. Start at an early age by giving your child a few simple rules about dogs:

Safety tips For Dog Owners

No matter how sweet and lovable your furbaby is, he can still bite given the right (or wrong) combination of circumstances. Fortunately, there are some things that you can do to help prevent the unthinkable.

Handling Dogs You Do Not Know

It’s not just your own four-footed friend that you need to be concerned about. What steps can you take to prevent unwanted encounters with another canine?
When communicating with health professionals and other people about dog bites, it’s helpful to have a classification system that standardizes the nature of the attack. Dr. Ian Dunbar developed a six-level scale to classify dog bites in a way that facilitates consistent and understandable discussions about these injuries.

Level 1

The dog acts aggressive or obnoxious but does not contact the skin with his teeth.

Level 2

The teeth contact the skin, but there are no puncture wounds. There may be surface nicks(less than 1/10 inch deep) and minimal bleeding.
Level 1 and 2 incidents comprise more than 99% of dog bites. These dogs are more likely fearful, overly excited, or out of control than they are dangerous. Owners should provide basic obedience training and conditioning to prevent further incidents.

Level 3

There is a single bite with no more than four puncture wounds. The punctures up to ½ the length of the dog’s canine teeth. There could be lacerations in one direction from pulling away from the dog or the owner pulling the dog off the person.
Fido’s prognosis with this type of bite is fair to good. Owners must be on board to provide bite-inhibition training. Treatment will take time and comes with some risk.

Level 4

There’s a single bite with one to four puncture wounds. At least one of the wounds is greater than half the length of the pup’s canine teeth. You may also see bruising or lacerations in two directions because the pooch clamped down or shook its head.
In this case, the dog lacks bite inhibition and is considered dangerous. Prognosis for the pooch is poor, and training should only be attempted under strict conditions and only if the owner is 100% committed to reconditioning their pup.

Level 5

This is an incident with either multiple bites or multiple attacks. In the case of multiple bites, at least two injuries must be level 4 bites. With multiple attacks, each incident must have at least one level 4 injury.

Level 6

The victim is dead.
These dogs are extremely dangerous and cannot be trusted around people. Dr. Dunbar recommends euthanasia in these cases.
10 Dog Breeds with the Strongest Bite
All dogs are not created equal. Some breeds have a much stronger bite force than others. Those that exert more force can go beyond a flesh wound and may break or crush bones. Scientists measure the bite force using PSI.
PSI stands for pounds per square inch, and it is a measure of how much force is exerted over one square inch of a pound. To give you a comparative idea of some forces:
Dog bite strength relies on a body size, skull size, and jaw shape. While many people may think of American Pit Bulls, Rottweilers, or German Shepherds as the most fearsome dogs, Mastiff breeds actually top the list for bite force. Let’s look at the top 10 dogs for strongest bite:

#10 Leonberger

Leonbergers are normally gentle family dogs, but they are enormous. If angered, their bite force can reach 399 PSI

#9 Wolfdog

A wolf-dog hybrid can be unpredictable in their behavior. They’re a cross between a domestic canine and a feral wolf. Their bite force can top out at 406 PSI

#8 Dogo Argentino

This breed from Argentina is a descendant of the Cordobra Fighting Dog. It is a hunting and guard dog with a maximum bite force of 500 PSI.

#7 Dogo Canerio

The Dogo Canerio hails from the Canary Islands and was a popular war and dog fighting pooch. It has a bite strength of 540 PSI.

#6 English Mastiff

Another war dog, today’s English Mastiff is a gentle giant and a good family dog. If you provoke them to bite, however, their bite force can be 556 PSI.

#5 Tosa Inu

In the early 20th century, breeders in Japan crossbred several European breeds to develop a formidable canine warrior. The resulting Tosa Inu is a loyal companion that has the ability to exert 556 PSI if it bites you.

#4 Dogue de Bordeaux

This normally laid back French Mastiff breed is usually calm, quiet, and good with kids. If you threaten or provoke it, however, its top bite force is 556 PSI.

#3 Cane Corso

The fearless Cane Corso from Italy once served as a sentry and attack dog. They can be affectionate to their family members but may be overprotective. Their bite strength can reach 700 PSI.

#2 American Bandogge

Not a recognized breed by the American Kennel Club, the “Bandog” refers to a muscular crossbreed of ancient Greek dogs known as Molossers. These were war and guarding canines, and they have a top bite force of 730 PSI.

#1 Kangal

The Kangal is a Turkish guard dog known for gentleness, loyalty, and protectiveness. Their bite strength wins the title with 743 PSI.
This happened in our household about 8 years ago. My husband was coming home from an early morning walk with our Springer-lab mix when the paper delivery person was cutting across our lawn. He was in front of our baby daughter’s window when our furbaby saw him and perceived him as a threat. The young man waved a rolled newspaper in front of her, and she lunged and bit him on the leg. Fortunately, this was the only time she ever bit anyone, and she was up to date on her rabies vaccinations. What did we do, and what should you do?
It’s important to stay calm and get control of the situation. If you take immediate action, you can help diffuse a tense situation and avoid liability. Here are steps you can take if Fido bites someone.

If My Dog Bites Someone, Will I Have to Put It Down?

Not necessarily. It will depend on the laws in your area and your pup’s past history. In our pooch’s case, she had no past history of aggression. The laws in our area required that we keep her under house and yard quarantine and observe her closely for 10 days. This was to confirm that she was not transmitting the rabies virus at the time of the bite.
If your pup has no history of aggression, many localities will quarantine the dog either at your home or a state facility. If it is a second offense, Fido may be placed on a dangerous dog list. With repeated attacks or bites, the state will require euthanization.
Dog Bite Insurance
How can you protect yourself if your furbaby bites someone and the victim seeks legal damages? Will you need dog bite insurance? In many cases, your pup’s actions may be covered by your homeowner’s or renter’s insurance. Personal liability clauses often include protection in the event your pup bites a person or damages their property. There are exceptions for some high-risk breeds like pit bulls. You may also encounter a higher premium if your pooch has a history of biting. To be sure of your coverage, let your insurance agent know about your furbaby’s history and breed.
When Fido bites someone and medical care is needed, the doctor will enter an ICD 10 code for insurance purposes. Public health officials use the same system if they are involved.
ICD 10 stands for International Statistical Classification of Diseases and Related Health Problems 10th Revision which is published by the World Health Organization. The codes are alphanumeric combinations of 3-7 characters. They’re used to describe a specific diagnosis for a(n).
In the code, the first three characters specify the category of the condition. For example, contact with a dog codes is W54. The next three characters indicate the anatomical location and severity of the condition along with other clinical information. The final character is an extension that indicates if this is an initial event, a recurrence, or a complication.

ICD 10 Codes for Dog Bites

In the case of dog bites, the ICD 10 codes are as follows:

Final Thoughts

In the case of dog bites, it’s good to follow the Boy Scout motto, “Always be prepared.” Nobody wants to think about injuries from canines. That’s why knowing how to respond after an attack and what you can do to prevent one in the first place is important. Hopefully, with education and proactivity we can keep both dog and man safe.
