Lyme Disease in Dogs
This page is educational reference material for preparing questions. A licensed veterinarian examines the animal, makes the diagnosis, and sets the treatment.
Lyme disease in dogs from tick bites. Covers symptoms, testing, antibiotic treatment, vaccination, and tick prevention strategies.
Causes and Risk Factors
Multiple factors can contribute to the development of this condition.
- Genetic predisposition: Certain breeds are at higher risk due to inherited traits
- Age: Some conditions are more common in puppies/kittens or senior pets
- Environmental factors: Diet, toxin exposure, stress, and living conditions play a role
- Underlying health issues: Other conditions may increase susceptibility
- Immune system status: Compromised immune function can predispose to disease
Symptoms to Watch For
Early detection significantly improves treatment outcomes. Watch for these signs.
- Changes in appetite, water consumption, or weight
- Behavioral changes including lethargy, restlessness, or hiding
- Physical symptoms specific to the affected body system
- Changes in bathroom habits (frequency, appearance, straining)
- Visible discomfort, pain response to touch, or changes in posture
- Respiratory changes, coughing, or labored breathing
When to See the Vet Immediately
Align the recommendations below with your animal's actual weight trajectory, current activity patterns, and any medications the veterinary team is already managing.
Diagnosis
Lyme disease in dogs is a clinical diagnosis backed by serology in a dog with compatible signs. The veterinarian looks for shifting-leg lameness, fever, or protein-losing kidney disease, and pairs that with a C6 antibody assay or a clinic Lyme test. Bloodwork and a urine protein check look for the kidney form. The 2018 ACVIM Lyme consensus is the reference this workup follows, and the questions lower on this page separate exposure from illness.
Treatment Options
A dog with clinical Lyme borreliosis is treated with an antibiotic the veterinarian selects, commonly a tetracycline such as doxycycline, at a dose and length the veterinarian sets. Lyme nephritis is not that same short course. It is a protein-losing nephropathy and may need hospitalization, fluids, and kidney care. A healthy dog with only an antibody result is not automatically put on antibiotics.
Prevention and Management
- Regular veterinary checkups (as recommended by the AVMA for all companion animals) for early detection (annually, or semi-annually for seniors)
- Maintain a healthy weight through proper nutrition and exercise
- Keep vaccinations and preventive medications current
- Breed-specific health screenings recommended by your veterinarian
- Provide a low-stress, enriched environment
- Follow your vet's recommendations for diet and lifestyle modifications
Cost of Treatment
Treatment costs vary based on severity and duration.
| Treatment Type | Estimated Cost Range |
|---|---|
| Initial Diagnosis | $200 – $800 |
| Medication (monthly) | $30 – $200 |
| Ongoing Management (annual) | $500 – $3,000 |
Is this condition curable?
Uncomplicated Lyme disease in dogs, the fever and shifting-leg lameness caused by Borrelia burgdorferi, usually improves after a veterinarian-chosen antibiotic. The 2018 ACVIM consensus (Littman and colleagues, Journal of Veterinary Internal Medicine) treats that illness as responsive, while Lyme nephritis, the protein-losing kidney form, often gets worse despite antibiotics. A positive antibody test by itself shows exposure. Exposure alone does not get an antibiotic.
How can I afford treatment?
Split the Lyme bill before any kidney test is run. A SNAP or C6 antibody test plus a short antibiotic course is a primary-care visit. Protein in the urine, a chemistry panel, and hospitalization for Lyme nephritis are the expensive branch. Ask the clinic to price those two paths separately. A policy started after the positive test will treat the infection as pre-existing.
