Preventing Lyme Disease In Dogs

April is Prevent Lyme in Dogs Month. Lyme disease is caused by Borrelia burgdorferi, a bacterium transmitted by the bite of infected deer ticks. It is the most commonly reported vector-borne disease among Americans, and is a serious health concern for dogs, especially here in the Mid-Atlantic.

Thankfully, not all pets that test positive become actively infected, but the ones that do can become severely ill with some or all of the following symptoms:

  • Fever
  • Loss of appetite
  • Lameness
  • Joint swelling
  • Decreased activity
  • Kidney disease and failure

Ticks can also carry other diseases such as anaplasmosis, ehrlichiosis or Rocky Mountain spotted fever, so the best offense is a good defense aimed at preventing the tick bites that cause the disease in the first place.

To help prevent Lyme disease, people with pets should:

  • Use reliable tick preventive products. Speak with your veterinarian about what tick preventive product is right for your pet. Many over-the-counter products do not cover all species of ticks, so talking to your veterinarian about what’s best for your pet is essential.
  • Protect against Lyme disease by using a safe and effective yearly vaccine. This can help prevent contracting the disease, or lessen symptoms if exposed. In addition to preventing your dog from contracting Lyme disease, a vaccine can kill the Lyme-causing bacteria within the tick, which means that tick cannot transmit Lyme disease to you or members of your household. This Lyme vaccine also has a guarantee from the manufacturer that will pay for treatment of Lyme disease if your pet contracts it while following the appropriate vaccine schedule.
  • When possible, avoid areas where ticks might be found. These include tall grasses, marshes and wooded areas.
  • Once indoors, check for ticks on both yourself and your animals.
