Lyme Disease in Dogs

Doug Collins

Mode of Transmission

Lyme disease in dogs is transmitted by infected deer ticks found in grassy or wooded areas through their bites. Prevention is key to safeguarding dogs from this disease.

Geographic Distribution

Lyme disease occurs worldwide but is more prevalent in certain regions, including the northeastern and upper midwestern United States, as well as parts of Europe and Asia.


Lyme disease in dogs can cause symptoms like lameness, fever, loss of appetite, and joint pain, but some infected dogs may not display any visible signs of the disease. Timely veterinary care is important for diagnosis and treatment.


Diagnosis of Lyme disease in dogs typically involves a combination of clinical signs, a thorough physical examination, blood tests (e.g., antibody tests or PCR tests), and sometimes joint fluid analysis.


Lyme disease in dogs is treated with antibiotics like doxycycline or amoxicillin. Treatment duration varies based on infection severity and the dog's response to antibiotics.


Preventing Lyme disease in dogs involves regular tick checks, using recommended tick preventive products, and avoiding tick-infested areas whenever possible. Taking proactive measures is crucial for reducing the risk of infection.


A Lyme disease vaccine is available for dogs, helping prevent the disease or lessen its severity if a vaccinated dog is infected. Consult your vet to assess its suitability based on your location and lifestyle.

Tick Control

Tick control measures like yard maintenance, repellents, and tick control products for dogs reduce tick bites and lower the risk of Lyme disease.

Long-Term Effects

Untreated Lyme disease can result in severe complications such as kidney damage, joint issues, and neurological problems. Prompt diagnosis and treatment are vital to prevent long-term effects.
