If you live in Ontario and share your life with a dog, tick season isn't really a season anymore. It's a habit. Somewhere between late March and the first hard freeze — and often on either side of that — blacklegged ticks are quietly waking up on the forest floor, in the tall grass at the edge of the trail, and in the leaf piles at the back of your own yard. It only takes a few degrees above freezing and a bit of humidity to get them moving.

None of that is a reason to keep your dog inside. Ontario is one of the best places on the planet to raise a dog, and the trails, conservation areas, and off-leash networks that make life here so good for our dogs are worth every muddy paw. What we do need — every single one of us, from first-time puppy families to seasoned show homes — is a calm, consistent tick-check routine. That is the single most protective thing you can do between vet visits.

Why Ontario's tick map keeps expanding

Public Health Ontario has been tracking the northward creep of blacklegged (deer) ticks for years, and the map that used to hug the Long Point and Thousand Islands areas now covers most of southern and eastern Ontario, a good chunk of the near north, and pockets that keep surprising people — including neighbourhoods well inside the GTA. Migrating birds carry ticks far beyond the "established" zones every spring, which is why your vet may treat "risk area" as "the whole province" during peak months.

The practical takeaway isn't fear. It's awareness. A dog that has spent thirty minutes in a Toronto ravine, an Ottawa greenbelt, a Muskoka cottage lot, or a friend's back forty near Guelph has been in tick country. Check accordingly.

When Ontario's tick season really runs

Two peaks, one long middle:

• Spring surge (roughly April–June). Adult ticks that overwintered are hungry and active as soon as daytime temperatures push past 4°C. This is when we see the most tick pulls at Paw Privileges partner clinics.

• Summer lull (July–August). Nymphs are active and — because they're the size of a poppy seed — they're the hardest to spot. Don't let the "slower" reputation of midsummer fool you.

• Fall resurgence (September–November). Adults come back hungry before winter. Warm November afternoons are a classic "surprise tick" window.

Snow on the ground is not a guarantee of safety. Every mild-winter thaw is a reminder to keep the habit going.

Build the habit: the five-minute tick check

The goal isn't a clinical exam. It's a five-minute, hands-on greeting after every outdoor adventure — trail, park, cottage dock, or even a long backyard sniff. Do it in good light, sitting on the floor with your dog, and turn it into the last step of coming home. Most dogs learn to lean into it.

Work top to tail, and use your fingertips (not just your eyes). Ticks love warm, hidden, low-traffic spots:

• Around the face: muzzle, lips, chin, eyelids, and — the classic — the folds inside and behind the ears.

• Neck and collar area: slip the collar off and run your fingers through the ruff. Ticks love the shelter of a collar.

• Armpits and chest: pull each front leg gently forward and feel the "pit." Thin-skinned, warm, sheltered — perfect real estate for a tick.

• Belly, groin, and inner thighs: especially on light-bellied dogs where they show up faster.

• Under the tail and around the vent: awkward, and often the first place you'll find one.

• Between every toe and up the leg feathering: ticks catch on furnishings first, then climb. Long-coated breeds (goldens, spaniels, doodles, most sport dogs) need extra time here.

• Tail base and down the topline: finish where you started, running your palm against the coat.

You're feeling for a small bump — anywhere from a pinhead (nymph) to a grape (fully engorged). If your fingertips catch on something that shouldn't be there, part the coat and look. A mole feels smooth and skin-anchored; a tick has legs.

Found one. Now what?

Stay calm — this is the easy part.

1. Use a proper tick tool or fine-tipped tweezers. Grip the tick as close to your dog's skin as you can, right at the mouthparts, not the body.

2. Pull straight up, slow and steady. No twisting, no yanking, no matches, no petroleum jelly, no essential oils. Those old wives' tricks make the tick regurgitate into the bite, which is exactly what we're trying to avoid.

3. Save the tick. Drop it in a small container or a sealed sandwich bag with a damp piece of paper towel. Note the date and where you were hiking.

4. Clean the bite site with soap and water or a mild antiseptic. A small red bump for a day or two is normal.

5. Call your vet. Every time. They may want you to submit the tick for identification (Ontario has free surveillance programs through Public Health), and they'll advise on tick-borne illness testing based on your dog''s history and prevention plan.

Prevention itself — collars, chewables, topicals, titres, vaccines where appropriate — is a conversation for your vet and, if you have one, your breeder. Every dog is different. Age, weight, other medications, breed sensitivities, and how much time you actually spend in tick country all matter. We won't recommend a specific product here because that's not our call to make; it's theirs.

What to watch for in the two weeks after a bite

Most tick bites in Ontario end with nothing more than a pulled tick and a good story. But the window that matters is the two to four weeks that follow. Loop your vet in early if you notice:

• Unexplained lameness that shifts from leg to leg

• Low energy, off food, or a dog who suddenly "isn't themselves"

• A fever, swollen joints, or swollen lymph nodes

• A bullseye-style rash (uncommon in dogs, but worth mentioning)

These signs don''t automatically mean Lyme, anaplasmosis, or ehrlichiosis — but they do mean "phone the vet, mention the tick pull, ask about testing." Early is always better.

Small changes that make a big difference at home

You don't need to redesign your yard. A few tweaks quietly reduce tick contact:

• Keep the lawn shorter around play areas and pathways.

• Rake leaves out of the dog's regular loop through the yard — leaf litter is a tick nursery.

• Put a wide, dry (mulch or gravel) buffer between lawn and forest edge if you back onto trees.

• Discourage rodents at the feeder — mice and chipmunks are the reservoir hosts that keep the local tick population fed.

• Trim tall grass at fence lines and along the sides of the house.

On the trail, walk down the middle of the path when you can, avoid brushing through tall grass, and do a quick "field check" of your dog's belly and legs before loading back into the car. It saves you finding a hitchhiker on the couch three hours later.

The Paw Privileges take

Tick season in Ontario has stopped being a scary story we tell in May and become a normal part of raising a dog well. Build the check into the arrival-home routine, keep your vet in the loop, and stop worrying about whether you're "doing enough." Consistency beats intensity every time.

Your dog wants the ravine, the shoreline, the conservation area, the leaf-crunchy walk down your own street. Give them all of it — and give them five minutes of good hands and good light when you get home. That's the whole job.
