Warmer Winters = Bigger Parasite Risks for Pets in Wisconsin
Climate patterns are shifting here in the Midwest — and that includes warmer winters and wetter seasons, which can help parasites survive and spread. In Wisconsin, public health experts say milder winters can mean more ticks surviving the cold and expanding their range. This increases the risk of tick-borne diseases like Lyme disease, ehrlichiosis, and anaplasmosis for both people and pets. Experts are tracking changes in tick behavior and working to raise awareness about prevention and safe outdoor practices.
👉 What pet owners should keep in mind:
🐾 Ticks can be active earlier and later in the season
🐾 Year-round parasite prevention keeps pets safer
🐾 Check your dog or cat after being outdoors
📍 Keeping your pets protected starts with awareness and proper prevention year-round.
