Lyme disease is caused by a bacteria called Borrelia burgdorferi, which is passed to dogs through a bite from the deer tick. The tick must remain attached to the dog's skin for one to two days before the bacteria can be transmitted.
Lyme disease can be a multi-systemic illness, with signs that may include fever, swollen lymph nodes, lameness, loss of appetite, heart disease, inflamed joints, and kidney disease. Disorders of the nervous system, while uncommon, may occur as well.
A vaccine is available to prevent dogs from developing Lyme disease, although some controversy exists regarding its use. An owner should consult with a veterinarian for vaccine recommendations.
