Lyme disease, caused by the bacterium Borrelia burgdorferi, is transmitted to dogs and humans through tick bites, particularly by the black-legged tick.

It’s crucial to recognize the symptoms early and consult a veterinarian for a proper diagnosis and treatment plan.

This post aims to explore the top three antibiotic treatments for Lyme disease in dogs, emphasizing the need for professional veterinary care​​​​.


Understanding Lyme Disease in Dogs

Symptoms of Lyme Disease in Dogs

The most common symptoms include;

  • fever
  • loss of appetite
  • reduced energy
  • shifting or intermittent lameness
  • generalized stiffness
  • discomfort or pain
  • swelling of joints

In severe cases, it can lead to kidney failure, cardiac, and neurological effects​​​​.

Not all dogs show symptoms, but those affected may exhibit a “walking on eggshells” demeanor due to generalized pain and high fever​​.

How Dogs Contract Lyme Disease


Lyme disease is transmitted through the bite of an infected tick. Ticks latch onto dogs that pass through tall grasses, thick brush, marshes, and woods.

The disease can be hard to detect and may cause serious health problems if not treated promptly. It’s prevalent in the Northeast, Upper Midwest, and Pacific Coast of the U.S., with varying infection risks​​​​.
