A dog with Lyme disease often acts lethargic, loses appetite, and develops fever, but the most distinctive sign is intermittent, shifting lameness (limping that moves from leg to leg) due to painful, swollen joints, sometimes described as walking on eggshells. While many infected dogs show no symptoms, those that do can also experience swollen lymph nodes, weakness, vomiting, diarrhea, increased thirst/urination, and in severe cases, fatal kidney failure (Lyme nephritis).

Common Signs of Lyme Disease in Dogs

Lyme disease symptoms can vary, but some of the most common signs to watch for include: Lameness or painful, swollen joints. Fever and loss of appetite. Fatigue or decreased activity.

How quickly does Lyme disease affect a dog?

When do clinical signs of Lyme disease occur? Only 5-10% of infected animals are expected to show clinical signs of Lyme disease. They typically occur at the chronic disease stage and as early as 2-5 months after infection. Clinical signs can also develop much later.

What does a Lyme flare up look like in dogs?

Lameness, painful or swollen joints, fever, swollen lymph nodes, loss of appetite, and lethargy are the most common symptoms of Lyme disease in dogs and can range in severity. If left untreated, Lyme disease can lead to more serious symptoms, like damage to the kidney or the heart and nervous system.

What are at least 5 early signs of Lyme disease?

Early signs of Lyme disease often mimic the flu, including fever, chills, headache, fatigue, and muscle/joint aches, but the most distinctive sign is the erythema migrans (bull's-eye) rash, which appears at the bite site days to weeks later and expands. Other early symptoms include swollen lymph nodes and a stiff neck.

What is the rule of 7 for Lyme disease?

The "Rule of 7s" for Lyme disease is a clinical tool, primarily for children with suspected Lyme meningitis, that identifies low-risk patients based on three criteria: less than 7 days of headache, less than 70% cerebrospinal fluid (CSF) mononuclear cells, and no facial (7th) cranial nerve palsy, allowing for outpatient management while awaiting definitive test results, but clinical judgment is still crucial. There's also a general "rule of 7s" emphasizing early treatment (within 7 days), potential progression (7 weeks), and chronic forms (7 months) for Lyme management in broader contexts, though this is less a formal rule and more a guideline for timeliness.
 

How long should I watch my dog after a tick bite?

Watch your pet closely for changes in behavior or appetite if you know or suspect that it has been bitten by a tick. Signs of tickborne disease may not appear for 7-21 days or longer after a tick bite. Except for Lyme disease in dogs, pets cannot be vaccinated against tickborne diseases.

Can dogs fight off Lyme disease on their own?

The good news is that most dogs exposed to Lyme disease are able to fight off the infection themselves and do not develop an illness that requires treatment.

What can I give my dog for Lyme disease at home?

Some antibiotics, such as doxycycline, amoxicillin, clarithromycin, and azithromycin, can alleviate Lyme disease symptoms and be part of a proper treatment regimen for humans and dogs.

How rare is it for a dog to get Lyme disease?

It is estimated that only 3-10% of dogs exposed to an infected tick will develop illness associated with Lyme disease. The most common signs of illness are: Fever (103° to 105°F; 39.5° to 41°C), listless or lethargy, loss of appetite and interest in drinking.

What can be mistaken for Lyme disease in dogs?

A few conditions can be mistaken for Lyme disease depending on the clinical signs. These include other tick-borne infections (such as Anaplasmosis), septic arthritis, and cellulitis.

What are the neurological symptoms of Lyme in dogs?

If left to progress, Lyme disease can lead to more severe symptoms as the bacteria spreads throughout the body, causing damage to the kidneys, heart, joints, and nervous system4. Neurological symptoms of Lyme disease in dogs can include facial paralysis and seizures4.

Which dogs are most at risk for Lyme?

Lyme disease is very common in dogs and rare in other species of animals. Young dogs are more susceptible to disease than older dogs. Not all infected dogs will show signs of illness, however those that do most commonly suffer from acute arthritis characterized by hot, swollen and painful joints.

How long does a tick need to be attached to give you Lyme?

In most cases, a tick must be attached for 36 to 48 hours or more before the Lyme disease bacterium can be transmitted. If you remove it within 24 hours, the risk is greatly reduced. Symptoms of Lyme disease may take 3-30 days or longer to appear.

How to fight Lyme without antibiotics?

Essential oils like cinnamon bark, clove bud, and oregano might help fight Lyme bacteria, but more research is needed in humans. Some herbs, such as black walnut and cat's claw, show promise against Lyme disease in lab studies, but more research is needed on their effects in people.

How do dogs act if they get Lyme disease?

When dogs get Lyme disease, it typically starts with fever, lethargy, and/or random lameness in their legs. Symptoms may last for a day or two and appear again a week later. It can happen to the same limb or a different one and the pup's joints may be swollen, warm, or painful.

How much does it cost to test a dog for Lyme disease?

You will need to pay the veterinary examination fee, which ranges from $40 - $100, depending on your location. In addition, blood tests usually run about $80. Antibiotics should also be taken into consideration - in some areas, a 14-day supply of these medications can cost about $400 or even more.

How quickly can Lyme disease affect a dog?

In dogs that do become ill, signs of Lyme disease typically first show up 2-5 months after the dogs were first infected. By this time, the disease can be widespread throughout the body.

What other illnesses mimic Lyme disease?

Lyme disease, known as the "great imitator," mimics many conditions like fibromyalgia, chronic fatigue syndrome (CFS), and multiple sclerosis (MS), due to overlapping symptoms such as fatigue, joint pain, and cognitive issues (brain fog). It also resembles autoimmune diseases like rheumatoid arthritis (RA) and lupus, neurological disorders like ALS, and even simple issues like cellulitis, infections (like anaplasmosis/ehrlichiosis), and psychiatric conditions such as depression, making diagnosis challenging. 

What happens if Lyme disease is left untreated?

Lyme disease can affect your nervous system, leading to neurological complications, such as facial nerve palsy, meningitis, and cognitive problems. These symptoms can range from mild to severe and may persist for months or even years if the infection remains untreated.

What is stage 1 of Lyme disease?

The first stage of Lyme disease, called early localized Lyme disease, typically starts days to weeks after an infected tick bite and features a spreading "bull's-eye" rash (erythema migrans) along with flu-like symptoms like fever, chills, headache, fatigue, muscle aches, and swollen lymph nodes, though the rash isn't always present and can look different. Early treatment in this stage is crucial for preventing more severe, later-stage symptoms.
