Lyme Disease Prevention in Dogs

Lyme disease is a serious and potentially debilitating illness that affects not only humans, but also our beloved pets, including dogs. 

As a responsible pet owner, it's crucial to understand the importance of Lyme disease prevention in dogs, including recognizing the disease's symptoms and learning the necessary steps to keep your furry friend healthy and safe. 

In this blog, we'll discuss what Lyme disease is, how it's transmitted to dogs, its effects on dogs, and the ways pet owners can protect their dogs from this disease.

What is Lyme Disease?

Lyme disease is a tick-borne illness caused by the bacterium Borrelia burgdorferi. This bacterium is primarily transmitted to dogs and humans through the bite of infected black-legged ticks, also known as deer ticks. 

The disease is named after the town of Lyme, Connecticut, where it was first identified in the United States in the 1970s. Lyme disease is more prevalent in certain regions, particularly in the northeastern, mid-Atlantic, and upper Midwest regions of the United States. It is also not uncommon to see cases on the West Coast, primarily in areas of Northern California. 

While Lyme disease may be more common in certain areas, there are still dogs diagnosed with the disease in all 50 states each year. 

How is Lyme Disease Transmitted to Dogs?

Dogs become infected with Lyme disease when they are bitten by a tick carrying the Borrelia burgdorferi bacterium. Ticks usually need to be attached to the dog for at least 24-48 hours to transmit the bacterium successfully. 

The risk of transmission is highest during the warmer months when ticks are most active, and dogs spend more time outdoors. However, this does not mean that there is no risk during the rest of the year; ticks can be a year-round threat in many places. 

How Does Lyme Disease Affect Dogs?

Lyme disease can cause various symptoms in dogs, which may vary in severity. Some common symptoms include:

  • Fever
  • Lethargy
  • Loss of appetite
  • Swollen lymph nodes
  • Lameness or joint pain

In some cases, Lyme disease can also lead to more severe health problems in dogs, such as kidney damage and neurological or cardiac issues. If left untreated, the disease can become chronic and cause long-term health complications.

If you suspect your dog has been exposed to Lyme disease, consult your veterinarian. They will perform a physical examination and may recommend blood tests to detect the presence of antibodies to the Borrelia Burgdorferi bacterium. It is important to note that a positive antibody test does not necessarily mean your dog is currently infected or experiencing symptoms, as it may indicate a past exposure.

If your dog is diagnosed with Lyme disease, your veterinarian will likely prescribe a course of antibiotics, usually doxycycline or amoxicillin. Most dogs show significant improvement within a few days of starting treatment. However, it is essential to complete the entire course of antibiotics as prescribed to ensure the infection is fully treated. This is often a 30-day course, but in certain cases continued medication may be needed if the infection persists. 

In some cases, additional medications may be recommended to manage symptoms such as pain and inflammation.

Protecting Your Dog from Lyme Disease

Here are some ways pet owners can protect their dogs from Lyme disease:

Tick prevention: Use tick preventatives, as recommended by your veterinarian. There are many different options, including oral medications like NexGard Soft Chews for Dogs, topical treatments like Revolution Topical Solution for Dogs, and tick collars like the Seresto Flea & Tick Collar for Dogs.  Ensure that the product you choose is suitable for your dog's size, age, and health condition. 

Regular tick checks: Perform thorough tick checks on your dog after spending time outdoors, especially in wooded or grassy areas. Pay close attention to areas where ticks can hide, such as the ears, between the toes, and under the collar.

Maintain a clean yard: Keep your yard well-maintained by mowing the lawn regularly, trimming bushes, and removing leaf litter. This helps create an environment that is less hospitable for ticks.

Vaccination: Talk to your veterinarian about the Lyme disease vaccine for dogs. While the vaccine may not provide complete protection, it can significantly reduce the risk of your dog developing the disease.

Prompt removal of ticks: If you find a tick on your dog, remove it promptly using a pair of fine-tipped tweezers or a specialized tick removal tool, such as the Tick Tornado Tick Remover. Grasp the tick as close to the skin as possible and pull it out with steady, even pressure. After removing the tick, disinfect the area and wash your hands thoroughly. 


Lyme disease can pose a significant risk to the health and well-being of your dog. By understanding the disease, taking preventive measures, and working closely with your veterinarian, you can help protect your furry companion from this potentially serious illness. Stay vigilant and proactive in safeguarding your dog's health, ensuring they can enjoy a happy, active life.
