How Veterinarians Diagnose and Treat Lyme Disease in Pets

By Calusa Veterinary Center | May 20, 2026

Lyme disease is one of the most common tick-borne illnesses affecting pets across the United States. While many pet owners associate Lyme disease with humans, dogs and even cats can also become infected after being bitten by an infected tick. Early detection and prompt treatment are essential to protecting your pet’s long-term health and preventing serious complications.

At Calusa Veterinary Center in Boca Raton, our team understands how concerning tick-borne illnesses can be for pet owners. Through advanced pet diagnostics care in Boca Raton and compassionate veterinary services, we help pets recover quickly and stay healthy year-round.

What Is Lyme Disease in Pets?

Lyme disease is caused by the bacterium Borrelia burgdorferi, which is transmitted through the bite of infected black-legged ticks, commonly called deer ticks. Dogs are much more likely than cats to develop symptoms, although any pet exposed to ticks may be at risk.

Ticks are commonly found in wooded areas, tall grass, parks, and even residential backyards. Once attached to a pet, a tick may transmit the bacteria after several hours of feeding.

Because symptoms may not appear immediately, many pet owners do not realize their companion has been exposed until the illness progresses.

Common Symptoms of Lyme Disease in Pets

The signs of Lyme disease can vary depending on the severity of the infection and how long it has been present. Some pets may show mild symptoms, while others develop more serious health concerns.

Common symptoms include:

  • Fever
  • Loss of appetite
  • Lethargy
  • Swollen lymph nodes
  • Joint pain
  • Limping that shifts from one leg to another
  • Stiffness or difficulty walking
  • Sensitivity to touch
  • Fatigue after exercise

In severe cases, Lyme disease can affect the kidneys, nervous system, or heart. Kidney complications are particularly dangerous and may become life-threatening if left untreated.

Pet owners should contact experienced veterinarians in Boca Raton if they notice unusual behavior, pain, or mobility issues in their pets.

How Veterinarians Diagnose Lyme Disease

Diagnosing Lyme disease can be challenging because many symptoms overlap with other illnesses and orthopedic conditions. Veterinarians use a combination of physical examinations, medical history, and diagnostic testing to confirm infection.

Reviewing Your Pet’s History

The diagnostic process often begins with questions about your pet’s lifestyle and environment. Your veterinarian may ask:

  • Has your pet recently been in wooded or grassy areas?
  • Have you noticed ticks on your pet?
  • Is your pet currently on tick prevention medication?
  • When did symptoms begin?

Understanding your pet’s exposure risk helps veterinarians determine whether Lyme disease testing is appropriate.

Physical Examination

During the examination, veterinarians carefully assess your pet’s joints, muscles, temperature, and overall condition. They may check for:

  • Joint swelling
  • Pain during movement
  • Fever
  • Dehydration
  • Enlarged lymph nodes

A physical exam also helps rule out injuries or other diseases that may mimic Lyme disease symptoms.

Blood Testing for Lyme Disease

One of the most effective ways veterinarians diagnose Lyme disease is through blood testing. Specialized tests detect antibodies produced in response to Lyme bacteria exposure.

Common diagnostic tests include:

SNAP Tests

SNAP tests provide fast in-clinic results and can identify exposure to Lyme disease as well as other tick-borne illnesses.

Comprehensive Blood Panels

Additional bloodwork helps evaluate your pet’s organ function and overall health. This is especially important if kidney complications are suspected.

Urinalysis

Veterinarians may analyze urine samples to look for protein loss or kidney damage associated with advanced Lyme disease.

Advanced pet diagnostics care Boca Raton allows veterinarians to accurately identify infections and develop personalized treatment plans for pets.

Treatment Options for Lyme Disease in Pets

Fortunately, Lyme disease is treatable in many pets when diagnosed early. Treatment focuses on eliminating infection, reducing inflammation, and relieving discomfort.

Antibiotic Therapy

Antibiotics are the primary treatment for Lyme disease. Doxycycline is one of the most commonly prescribed medications because it effectively targets the Lyme bacteria.

Most pets begin improving within a few days of starting treatment, although the full antibiotic course typically lasts several weeks.

It is important for pet owners to follow medication instructions carefully and complete the entire treatment plan even if symptoms improve early.

Pain Management and Supportive Care

Some pets experience significant joint pain or inflammation. Veterinarians may recommend:

  • Anti-inflammatory medications
  • Pain relief therapy
  • Joint supplements
  • Rest and reduced physical activity

Supportive care helps pets recover more comfortably while reducing stress on affected joints.

Monitoring Kidney Health

Because Lyme disease can sometimes damage the kidneys, ongoing monitoring may be necessary. Follow-up blood tests and urinalysis help veterinarians track recovery and identify complications early.

Pets with severe kidney involvement may require more intensive care, including fluid therapy or specialized diets.

Preventing Lyme Disease in Pets

Prevention is one of the most effective ways to protect pets from Lyme disease and other tick-borne illnesses.

Use Tick Prevention Products

Veterinarians may recommend:

  • Oral tick preventatives
  • Topical treatments
  • Tick collars
  • Monthly parasite prevention medications

Using veterinarian-approved products consistently is essential for effective protection.

Check Your Pet for Ticks Regularly

After outdoor activities, inspect your pet carefully for ticks, especially around:

  • Ears
  • Neck
  • Between toes
  • Under collars
  • Armpits

Removing ticks promptly can reduce the risk of disease transmission.

Maintain Your Yard

Reducing tick habitats around your home can help minimize exposure. Pet owners should:

  • Keep grass trimmed
  • Remove leaf piles
  • Clear overgrown vegetation
  • Limit wildlife access to the yard

Schedule Routine Veterinary Exams

Regular wellness visits help veterinarians identify early health concerns before they become serious. Routine exams also ensure your pet stays current on parasite prevention products and screenings.

If you suspect your pet may have Lyme disease or another tick-borne illness, it is important to book an appointment with an experienced veterinary team as soon as possible.
