Prevent Lyme Disease in Dogs Month is a month-long campaign that takes place in April to help raise awareness about preventing Lyme disease in dogs. As temperatures begin to rise in the spring months, the prevalence of deer ticks increases in outdoor environments. Many of them carry the bacteria that causes Lyme disease in dogs when bitten. The campaign helps provide dog owners with a greater understanding of the risks and the methods that help their dogs avoid future health problems.

History of Prevent Lyme Disease in Dogs Month

Prevent Lyme Disease in Dogs Month is an annual campaign started by the Lyme Disease Foundation. It runs through the month of April and aims to spread awareness on how to prevent, identify and treat Lyme disease in dogs.

As springtime rolls around, dogs and their owners are more likely to spend time outdoors. At this time of year, black-legged or deer ticks are more common in warmer climates, thereby presenting potential health hazards to dogs. Prevent Lyme Disease in Dogs Month occurs at the peak of spring because dogs are at an increased risk of contracting Lyme disease, or borreliosis, during this time. Deer ticks tend to carry with them the ‘Borrelia Burgdorfer’ bacteria which can cause serious complications in dogs. When bitten dogs experience symptoms including joint pain, swelling, fevers, and kidney problems, all of which are indicative of Lyme disease. While not all deer ticks carry the bacteria, certain areas have been identified as high-risk for Lyme disease contraction. The highest prevalence of deer ticks can be found ranging from the Midwest to the Eastern United States.

Signs of Lyme disease in dogs are often not immediately obvious — sometimes taking two to five months to fully appear. The first signs typically are gradual issues with the dog’s knee and elbow joints and increased lethargy. In some cases, the concerns can disappear in a short time, but some cases could be long-term and can result in kidney and heart problems, which could be fatal. While treatment for Lyme disease is available, it is recommended that dog owners take the necessary steps to identify and prevent the issues as early as possible.
