Evidence of antibody to Anaplasma spp. in dogs by county, grouped according to percent positive tests. No results (<30) were received from counties shaded gray, precluding interpretation of the presence of antibody in dogs from these areas. Counties depicted in white had no dogs reported as positive (0%). Remaining counties were coded as follows: 0.1-0.5% (light green), 0.5-1.0% (green), 1.1-5.0% (dark green), and > 5.0% (very dark green).
