Lyme Vaccine

Lyme disease is caused by the spirochete (type of bacterium), Borrelia burgdorferi. It is transmitted to dogs through the bite of an infected tick. Once in the bloodstream, the Lyme disease organism is carried to many parts of the body and is likely to localize in joints or kidneys. The most common type of tick to carry Lyme disease is the deer tick, also known as the black-legged tick.  These ticks are found everywhere in Nova Scotia.

​

Many dogs affected with Lyme disease are taken to a veterinarian because they seem to be experiencing generalized pain and have stopped eating. Often, these pets have high fevers and may also be limping. This painful lameness often appears suddenly and may shift from one leg to another and if left untreated, may eventually disappear, only to recur weeks or months later.

​

Non-specific signs which may indicate that Lyme disease is affecting the kidneys include vomiting, lethargy, anorexia (lack of appetite), and weight loss. The kidney form of the disease is less common but often fatal.

​

Most dogs infected with the Lyme disease organism take two to five months before they show symptoms. By this time, the disease may be widespread throughout the body.

​

Vaccination against Lyme disease is recommended for pets that live in endemic areas or that travel to areas where Lyme disease is prevalent.  Most dogs that live in Nova Scotia should be vaccinated for lyme.   This vaccine is initially given twice, at three to four-week intervals. Annual revaccination is necessary to maintain your dog’s immunity. The decision to vaccinate against Lyme disease can be discussed with your veterinarian based on your dog’s lifestyle and individual risk assessment.
