Why tick risk is becoming harder to predict in practice

Ticks are becoming a less predictable, more year-round threat for dogs, cats, and the people around them. Across the UK, surveillance and veterinary commentary point to expanding tick distribution, longer activity periods, and a disease picture that now demands attention beyond Lyme disease alone. UKHSA’s Tick Surveillance Scheme says Ixodes ricinus, the main Lyme vector, remains widespread and is being tracked for distribution, seasonality, and host associations, while recent UKHSA research describes continued expansion in the range of Lyme-vector ticks. In parallel, ESCCAP guidance and veterinary experts are emphasizing that climate, habitat change, and animal movement are reshaping exposure risk. In North America, Susan E. Little, DVM, PhD, DACVM, has made a similar case in dvm360 coverage, urging “every pet, every month, all year long” prevention because tick activity is now effectively year-round in many areas. A separate Binghamton University report adds a One Health signal: farmers in the Northeast described repeated tick exposure, with some reporting as many as 70 encounters in six months.

Why it matters: For veterinary professionals, this is a risk-environment story as much as a pathogen story. The practical shift is toward year-round prevention, broader differentials when compatible signs appear, and more deliberate client communication about where exposure happens. Ticks are no longer just a countryside, summer, or travel-associated issue. Dogs and cats can pick them up in a wider range of settings, and veterinary teams may need to think not only about borreliosis, but also about other tick-borne infections relevant to geography, travel, or emerging local transmission. Dogs also remain useful sentinels for human exposure risk, which makes tick discussions part of routine preventive care, not just seasonal parasite advice. (theherd.news)

What to watch: Expect more emphasis on surveillance, local risk mapping, and year-round prevention messaging as UK and international data continue to show shifting tick seasonality and exposure patterns. (ukhsa-dashboard.data.gov.uk)
