How dogs are affected by tick-borne diseases in your region

The Companion Animal Parasite Council (CAPC) provides great data each year on how tick-borne diseases impact dogs in each region of the United States. The data is broken out by the most common tick-borne diseases such as Lyme, ehrlichiosis, and anaplasmosis. Each of these diseases is passed along by different tick species, and one may be more common in your state than another depending on which tick species reside in your area.  

To help identify the higher risk areas for each disease, highest risk areas are featured in a deep orange color and areas with less risk have the lightest orange color. As you view the maps below, take note that each disease is found nationwide but in various degrees. Take a look at your state to see which tick-borne disease your dog is most at risk for contracting.

Click on each map below to learn more about each disease in your state and county. Please note, not all counties have data associated with it, and an important note is that the numbers shown in the map (total positive cases and total pets tested) are estimated to be only 30% of the true tick-borne illnesses in each state. This is because the numbers only account for the tests and results that are sent into IDEXX Laboratories and ANTECH Diagnostics, not those tests that are run in an individual hospital where they analyze results in house. There is potential that the numbers shown on the site can actually be up to 3X what is shown.


Lyme Disease Prevalence

Ehrlichiosis Prevalence

Anaplasmosis Prevalence

These maps were provided by the Companion Animal Parasite Council with data from IDEXX Laboratories and ANTECH Diagnostics.

Keeping in mind what was noted above about the numbers actually being 3X what is reported, the data tells us that approximately 1 in 16 dogs tested for Lyme were positive, 1 in 33 dogs tested for ehrlichiosis were positive, and 1 in 26 dogs tested for anaplasmosis were positive.

Understanding what tick-borne diseases look like in your state and county is an important step in understanding why protecting your pet should happen year-round. If you have questions, feel free to visit our staff at a Community Clinic near you. Click here to find a clinic near you.
