Tick Prevention
Q: Why do I need to start giving my pet tick prevention when there is still snow on the ground?
A: You’re not alone in wondering why veterinarians often recommend starting (or continuing) tick prevention when there’s still snow on the ground. The short answer: ticks, fleas, and even mosquitoes are much tougher than most of us think—and winters aren’t what they used to be.
Q: Why start tick prevention early?
A: Ticks don’t all die off in winter. Many species, including the blacklegged (deer) tick that spreads Lyme disease, can stay active at temperatures as low as 4°C (about 40°F)—which means those mild winter days or early spring thaws can wake them up fast.
Recent research and veterinary reports from across North America show these parasites are surviving longer and farther north than ever before, thanks to milder winters and more urban green spaces that provide shelter under leaves and snow.
In short, “tick season” is now nearly year-round in many areas. Waiting until you see ticks can leave your pet unprotected during those early warm spells when they first become active.
Q: Do cats really need tick and heartworm prevention?
A: Yes—especially cats that go outdoors, even part-time. Cats can get ticks just like dogs and are at risk for Lyme disease and other tick-borne infections. They can also contract heartworm from a single mosquito bite. While cats are less likely than dogs to develop heartworm disease, when they do, it’s often more severe and harder to treat.
Bottom line
- Start (or continue) prevention early—before ticks become active.
- Use vet-approved products designed specifically for dogs or cats (never share between species).
- Keep it consistent year-round for the most reliable protection.
