3 min read

If you’re getting ready to take your dog on a trip to the countryside, or even on the usual walk in the park, there’s something else to consider besides checking the weather and planning the route: ticks.

Keep reading to find out more about this tick-borne disease and what you can do to help prevent it.

 

What is Lyme disease in dogs?

Lyme disease in dogs is a tick-transmitted disease caused by a type of bacteria called Borrelia bergdorferi. This spiral-shaped bacterium gets into your pet’s bloodstream via a tick bite. Most commonly, the joints and the kidneys are affected by Lyme disease, but it can spread around the body.

 

What are the symptoms of Lyme disease?

In humans Lyme disease is associated with a characteristic bullseye rash, however this is not generally the case in our pets. While some pets will never display any symptoms, the most common signs of Lyme disease in dogs are:

  • Lethargy
  • Fever
  • Limping
  • Lack of appetite
  • Swollen joints

Although severe cases of the disease are not typically very common, it is possible for the condition to progress to a point where it becomes fatal. Neurological symptoms or kidney failure can be seen in more severe cases, so it’s important to talk to your vet if you notice any symptoms in your pet, particularly if you have found a tick on them.

The symptoms of Lyme disease are not very specific, and can indicate a variety of other illnesses including other bacterial infections. This is why blood tests are necessary. These tests look for specific antibodies produced by the pet’s body when trying to fight an active Lyme disease infection.

However, it can take between three to six weeks after the infection for antibodies to be produced and therefore detected by blood tests. This is why your vet is likely to run other tests too, such as a complete blood cell count, urinalysis or joint fluid analysis.


What is the treatment for Lyme disease in dogs?

Lyme disease is caused by bacteria, so a course of antibiotics will often be prescribed. The initial course of antibiotics typically lasts a month but may be prolonged if necessary.
