What Is Lyme Disease And How Does It Infect Dogs
This infectious condition of the blood vessels can affect almost any species of mammal, although it is most common in dogs. Lyme disease is a condition caused by the bacterium Borrelia burgdorferi. In humans, symptoms include fever, headache, fatigue, and a characteristic skin rash.
Lyme disease cannot penetrate the skin, so your dog will become infected after contact with a tick carrying Borrelia burgdorferi, the pathogens that cause Lyme disease. Each year,an estimated 30,000 cases are reported to the Center for Disease Control, though the actual number of infected people is thought to be much higher.
While Lyme disease can be debilitating in humans and animals, its also highly treatable. The sooner you can spot the symptoms of Lyme disease in your dog, the better chance you have of getting them back on their feet quickly. If left untreated, Lyme disease can wreak havoc on your dogs body and cause irreparable organ damage.
What Are The Signs And Symptoms Of Lyme Disease By Stages
There are three stages of Lyme disease, which are outlined below.
Stage 1 Early Localized Disease
- Occurs one to 30 days after a tick bite
- characteristic skin rash of Lyme disease
- migrating red rash with bullseye appearance occurring at or near the site of the tick bite
- asymptomatic or itches orburns
- develops around seven days after the tick bite
- rash expands over a matter of days
- an untreated rash may persist for two to three weeks
Stage 3 Late Disease
Stage 3 Lyme disease occurs months to years after the initial infection or a period of latency. Most patients presenting with the late disease do not have erythema migrans because the rash urges the patient to seek treatment earlier.
Symptoms of Stage 3 Lyme Disease may include the following:
- Skin manifestation:
- Acrodermatitis chronica atrophicans: found almost exclusively in patients of European descent. It commonly affects older women with bluish-red discoloration on the back of the hands, feet, knees, and elbows.

Stage : Quickly Expanding Rash
After being bitten by a black-legged tick, a quickly growing rash can appear. This is the earliest stage of Lyme disease, known as stage 1.
Most people who develop a rash, get it within days or weeks of being bitten by a tick.
Where you see the rash: If you develop a rash, it appears near the tick bit you. For most people, that means the back, groin, armpit, or a lower leg. However, a tick can bite you anywhere.
What the rash can look like: You may see a spot or bump on the skin, which is the bite mark. Around or near the bite mark, a rash develops. Some people see the bulls-eye rash . You can also have one of the other rashes shown here.
Early rash caused by Lyme disease
Notice the bite mark in the center of this early rash, which will expand quickly.
Bull’s-eye rash on woman’s upper arm
This is another early sign of Lyme disease.
Lyme disease rash with lighter color on the outside
This rash has expanded, but you can still see the bite mark in the center.
Rash from Lyme disease has begun to clear
As the rash begins to clear, the redness fades.
If you develop a rash during this stage, you may notice that it:
-
Feels smooth and warm to the touch
-
Causes a burning sensation
-
Itches or feels painful
-
Has an outer edge that feels scaly or crusty
When the rash and symptoms begin: According to the Centers for Disease Control and Prevention , the rash begins 3 to 30 days after the tick bites you.
About 50% of people who have Lyme disease develop flu-like symptoms , which include:

Chronic Lyme: What Happens When Lyme Goes Untreated
The Lyme community typically uses the term chronic Lyme disease to describe a range of physical, cognitive, and emotional symptoms that crop up after getting Lyme disease and persist for months to years after infection.
The risk of chronic Lyme increases the longer a Lyme infection goes untreated or undertreated. In other words, patients are more likely to recover fully if their Lyme infection is detected and treated as early as possible after the discovery of a tick bite. This stage is usually marked by symptoms such as fevers, chills, muscle aches, and sometimes rashes.
When left untreated or undertreated, however, Lyme disease can spread throughout the body and affect:
- The central nervous system
- Muscles and joints
As Lymedisease.org points out, these symptoms can evolve, disappear, and reappear at different times.
What Might A Doctor Misdiagnose Lyme Disease As
Ticks can carry a variety of different organisms and diseases with them.
The lone star tick can carry a disease known as southern tick-associated rash illness. The rash it causes to a Lyme disease rash. In addition, it can cause similar symptoms to Lyme disease, including fever, fatigue, joint and muscle aches, and headache.

Stage : Early Disseminated Lyme Disease
Early disseminated Lyme disease occurs several weeks to months after the tick bite.
Youll have a general feeling of being unwell, and a rash may appear in areas other than the tick bite.
This stage of the disease is primarily characterized by evidence of systemic infection, which means infection has spread throughout the body, including to other organs.
Symptoms can include:
- disturbances in heart rhythm, which can be caused by Lyme carditis
- neurologic conditions, such as numbness, tingling, facial and cranial nerve palsies, and meningitis
The symptoms of stages 1 and 2 can overlap.
How Should A Tick Be Removed
Grasp the mouthparts with tweezers as close as possible to the attachment site. Be careful not to squeeze, crush or puncture the body of the tick, which may contain infectious fluids. Pull firmly and steadily upward to remove the tick. After removing the tick, thoroughly disinfect the bite site and wash hands. The NYSDOH has created a video on proper tick removal and a printable card with steps on how to remove ticks . See or call a doctor if there are concerns about incomplete tick removal. Do not attempt to remove ticks by using petroleum jelly, lit cigarettes or other home remedies because these may actually increase the chance of contracting a tick-borne disease.

What Can Be Done To Prevent Lyme Disease
The best prevention of Lyme disease is through awareness. Generally, ticks cannot jump or fly onto a person. They wait in vegetation and cling to animals and humans when they brush by. When in a potentially tick-infested habitat take special care to prevent tick bites, such as wearing light-colored clothing and tucking pants into socks and shirt into pants. Check after every 2 to 3 hours of outdoor activity for ticks on clothing or skin. Brush off any ticks on clothing or skin before skin attachment occurs. A thorough check of body surfaces for attached ticks should be done at the end of the day. If removal of attached ticks occurs within 36 hours, the risk of tick-borne infection is minimal. For proper tick removal, please watch the video at Tick removal. A vaccine for Lyme disease is not currently available.
Insect repellents can be effective at reducing bites from ticks that can spread disease. If you decide to use a repellent, use only what and how much you need for your situation. More information on repellents can be found at Environmental Protection Agency – insect-repellents.
In addition:
Domestic animals can carry ticks into areas where you live so it is important to check pets for ticks before they enter the home.
What Is Borrelia Mayonii
Borrelia mayonii are a type of bacteria recently found in North America that can cause Lyme disease. These bacteria are different from the three types of bacteria that cause most cases of Lyme disease worldwide.
- Borrelia burgdorferi
- B. afzelii
- B. garinii
B. mayonii is the only species besides B. burgdorferi shown to cause Lyme disease in North America.

Stage : Changing Skin
In stage 3, few signs of Lyme disease appear on the skin. Most problems occur in the heart and nervous system, and these can be serious.
Where you see signs on your skin: If you were in Europe when bit by a tick, you may see changes to your skin in this late stage. These changes usually appear on a hand or foot. Some people develop this change on both of their hands or feet. It can also occur on a knee, elbow, or elsewhere.
What the skin looks like: The skin begins to swell, and you may notice some redness. These signs are caused by having a bacterial infection for a long time. The affected skin may also feel sore.
In time, the skin starts to harden and shrink, causing deep lines to form. If you have hair in the area, it tends to fall out. The sweat glands can die, and the skin often becomes so thin that it tears easily. The medical name for this condition is acrodermatitischronical atrophicans.
In stage 3, you may also see tumors on your skin. It is believed that the long-term infection and swelling in the lymph nodes can lead to a cancer known as cutaneous B-cell lymphoma.
Skin starts to harden and shrink, causing deep lines to form
The medical name for this condition is acrodermatitis chronical atrophicans. Swelling, hardened skin, and deep lines on the foot of someone who has had Lyme disease for years.
When you see signs of changing skin and symptoms: These tend to occur months or years after you are bitten by a tick.

Regression And Other Symptoms In Children
Children are the largest population of Lyme patients.
The CDC study of reported Lyme cases from 19922006 found that the incidence of new cases was highest among 5- to 14-year-olds . About one quarter of reported Lyme cases in the United States involve children under 14 years old .
Children can have all the signs and symptoms of Lyme that adults have, but they may have trouble telling you exactly what they feel or where it hurts.
You may notice a decline in school performance, or your childs mood swings may become problematic.
Your childs social and speech skills or motor coordination may regress. Or your child may lose their appetite.
Children are more likely than adults to have arthritis as an initial symptom 01267-2/fulltext#sec0040″ rel=”nofollow”> 25).
In a 2012 Nova Scotian study of children with Lyme, 65 percent developed Lyme arthritis . The knee was the most commonly affected joint.

What Causes Lyme Disease
Lyme disease is caused by bacteria. In the United States, this is usually a bacterium called Borrelia burgdorferi. It spreads to humans through the bite of an infected tick. The ticks that spread it are blacklegged ticks . They are usually found in the:
- Northeast
- Upper Midwest
- Pacific coast, especially northern California
These ticks can attach to any part your body. But they are often found in hard-to-see areas such as your groin, armpits, and scalp. Usually the tick must be attached to you for 36 to 48 hours or more to spread the bacterium to you.
What Are Signs And Symptoms Of The Third Stage Of Lyme Disease
Late stage Lyme disease can result when treatment is unsuccessful or started too late due to unrecognized symptoms or misdiagnosis. The late disseminated stage occurs months or years after initial infection and can have a major impact on a patients health and quality of life. Late Lyme arthritis is a third stage Lyme disease manifestation that involves fluid accumulation and pain in joints, particularly in the knee joints. Late neurologic disease is a 3rd stage condition that can also be debilitating and difficult to diagnose. Late disseminated Lyme disease symptoms include a variety of symptoms that are often neurologic in origin including: numbness in extremities, mental fogginess and concentration problems, and difficulty following conversations or processing information.

What If A Tick Bites My Dog
The more ticks in your region, the likelier it is that your furry pal will bring them home.
Your dog is much more likely to be bitten by a tick than you are. And where Lyme disease is common, up to 25% of dogs have had it at some point.
About 10% of dogs with Lyme disease will get sick. 7-21 days after a tick bite, your dog might seem like theyâre walking on eggshells. They also might have a fever and enlarged lymph nodes. Plus, they might seem tired. Dogs also get antibiotics for Lyme.
What if my dog brings ticks into my home?
Use a tick control product on your pet to prevent Lyme disease. Also, have your dog vaccinated against Lyme.
Check your dogâs whole body each day for bumps. If you notice a swollen area, see if thereâs a tick there. If you find a tick, wear gloves while you use tweezers to separate it from your dog. Then, put it in soapy water or alcohol, or flush it down the toilet.
Use alcohol to clean the spot on your dog where the tick was attached. Keep an eye on that spot, and also on your dog to make sure theyâre behaving normally. If you notice any changes, check with your vet.

Symptoms Of Lyme Disease
People with Lyme disease may react to it differently, and the symptoms can vary in severity.
Although Lyme disease is commonly divided into three stages early localized, early disseminated, and late disseminated symptoms can overlap. Some people will also present in a later stage of disease without having symptoms of earlier disease.
These are some of the more common symptoms of Lyme disease:
- a flat, circular rash that looks like a red oval or bulls-eye anywhere on your body
- other flu-like symptoms
These symptoms may occur soon after the infection, or months or years later.
Your child may have Lyme disease and not have the bulls-eye rash. According to an early study, results showed roughly 89 percent of children had a rash.
Lyme disease is best treated in the early stages. Treatment for early localized disease is a simple 10- to 14-day course of oral antibiotics to eliminate the infection.
Medications used to treat Lyme disease include:
- doxycycline, amoxicillin, or cefuroxime, which are first-line treatments in adults and children
- cefuroxime and amoxicillin, which are used to treat women who are nursing or breastfeeding
Intravenous antibiotics are used for some forms of Lyme disease, including those with cardiac or central nervous system involvement.
After improvement and to finish the course of treatment, healthcare providers will typically switch to an oral regimen. The complete course of treatment usually takes 1428 days.

Chronic Lyme Disease Vs Post
Patients typically use the term chronic Lyme disease to describe the cluster of symptoms that started after getting Lyme disease and that persist despite having received a course of antibiotic treatment which has been deemed curative by the Infectious Diseases Society of America. Patients say, “I’m not cured. I have symptoms now that I never had before Lyme disease. I’m fatigued 90% of the day. My muscles ache. My brain is in a fog. I can’t think clearly any more. I’m super sensitive to light and sound. What is going on? Chronic Lyme disease does exist – I’m a living example of it!”
Whatever one calls it, the experience is the same. Most often these patients experience profound fatigue, pain, and/or cognitive impairment. Mild to moderate levels of depression and anxiety may also accompany these symptoms, as the functional limitations can lead to social isolation, inability to work, and loss of sense of one’s identity as a provider, caretaker, or friend. Sometimes patients find themselves identifying with Job – the just and good man in the Bible whose life was wrecked by illness, death of loved ones, and economic disaster he felt tormented by God.
