Dogs get Lyme disease frequently in the U.S. Figure 1 displays illness prevalence to May 9, 2024. Out of 4,208,971 dogs who had reported tests,173,259 were positive. However, only those tested at commercial labs with records are included. In-house snap tests at thousands of clinics are not reported thus underreporting the severity of Lyme disease in dogs. Testing all canines, healthy or not, might demonstrate exposure rates of up to 95% in some locations. However, only 5–10% will develop clinical disease. Still, you don't want your dog in that 5%.
