What is Lyme disease?

Lyme disease, or Borreliosis, is a bacterial infection caused by Borrelia burgdorferi and spread by the bite of certain tick species. Though it can affect both humans and animals, borreliosis is most commonly seen in dogs.

This disease can cause a variety of symptoms, and if left untreated, can lead to serious health complications. The first signs of borreliosis in dogs are usually joint pain, stiffness, and lameness. These signs can worsen over time, and may also include fever, loss of appetite, weight loss, fatigue, and diarrhea. Dogs may also develop a “bull’s-eye” rash, which is a circular rash with central clearing, on the site of the tick’s bite.

Diagnosis of borreliosis in dogs is typically done through a combination of physical examination, testing of the tick’s saliva, and blood tests. Treatment usually involves a course of antibiotics, such as doxycycline or amoxicillin, along with anti-inflammatory medications to reduce joint pain and swelling. In cases of advanced disease, hospitalization and intravenous antibiotics may be necessary.

The best way to prevent borreliosis in dogs is to avoid tick exposure. Regularly check your dog for ticks, and use tick preventatives such as spot-on treatments, collars, shampoos, and sprays. Additionally, keep your yard and surrounding areas free of tall grass and other tick-friendly areas.

If your dog does become infected with Lyme disease or shows signs of the infection, it is vital to seek veterinary care immediately. Early diagnosis and treatment can help reduce the risk of long-term complications and ensure a good quality of life for your pet.
