ROCKFORD, Ill. (WIFR) -- A new report shows Rockford had the second-highest monthly percentage increase for positive heartworm tests.
The report comes from Companion Animal Parasite Council. It used data sourced from IDEXX Laboratories and ANTECH Diagnostics to rank the cities.
Only Sioux Falls, South Dakota experienced a larger jump for pets that had positive heartworm tests in June.
The CAPC says pets in the cities may have been exposed locally or through travel. Heartworm disease can impact areas with warmer climates and stable bodies of water, according to the CAPC.
Pet owners across the country are encouraged to talk with their veterinarian about annual heartworm testing and steps for year-round prevention.
