Why do ticks attach to the same spots on dogs over and over?

Ticks favor warm, moist, protected areas with thin fur because these spots offer easier access to skin and better cover from grooming or casual brushing. The ears, eyelids, collar line, armpits, groin, between the toes, and the tail base all share these traits, which is why CDC's guidance and CAPC's clinical observations both point to the same handful of zones repeatedly. Knowing this lets you focus a body check on high-yield areas rather than trying to inspect every inch of a dog's coat, which is slower and easier to do inconsistently.

How can I tell a tick apart from a skin tag, nipple, or scab?

The clearest tell is looking for tiny legs near where the bump meets the skin — a tick is an arachnid with eight legs, and even partially engorged, some leg movement or structure is usually visible up close or with a flashlight. Skin tags and nipples tend to be soft, symmetrical, and consistently present in the same spot over time, while scabs are flatter and drier. If you're ever unsure, gently part the fur and look closely before deciding — a magnifying glass or good phone camera zoom can help confirm what you're looking at.

Is it enough to just run my hands over my dog's coat?

A hands-over-the-coat pass is a reasonable first step but isn't enough on its own, especially for small or newly attached ticks, which can feel like nothing more than a slight roughness under the fur. The more reliable method is to actually part the fur at each of the known hot spots and look, rather than relying on touch alone through a full coat. This matters most in the ears, between the toes, and under the tail, where a light coat pass is easy to do without ever fully separating the fur down to skin.

Why is the nymph stage of the tick so easy to miss?

Nymphal blacklegged ticks are roughly the size of a poppy seed or pinhead, far smaller than the more familiar adult tick, which makes them easy to overlook during a quick check, especially on dark or long-haired dogs. Despite their tiny size, nymphs are responsible for a large share of Lyme disease transmission to people and pets because they're active during a long stretch of the year and are simply harder to spot and remove promptly. A flashlight and a slow, deliberate check of the known hot spots meaningfully improves your odds of catching one before it's been attached long.

How to Find Tick Hot Spots on Dogs During Body Checks

Your hands

Learning where to look is a homeowner skill, not a service call — a systematic body check is something any pet owner can master.

You've got this. It's a matter of knowing which handful of spots to check carefully, not searching your dog's entire coat inch by inch.

Whose job is this, really?

Pet-parasite questions belong to three genuinely different owners. Here's the desk that actually owns this one — even when the honest answer is 'not us.'

A technique to learn, not a symptom check

This page teaches where to look during a body check — there is no symptom in play here, just a skill worth building.

Escalate when

If a check turns up illness signs alongside an attached tick, or signs appear in the days-to-weeks after a bite, that becomes a veterinary question.

Your hands

The safe technique, step by step

CDC's dog diagram and CAPC guidance both point to the same handful of high-yield spots — work through them the same way every time.

Start at the head and work systematically toward the tail so you don't skip a zone.

A consistent order beats a random pass over the coat.

Check in and around the ears, including the ear-canal opening and the base of the flap, using a flashlight if needed.

CAPC notes the head, ears, and neck are especially common attachment sites.

Check around the eyelids gently, without pressing on the eye itself.

Thin skin and fur here make it an easy attachment spot.

Check under the collar by sliding it around and parting the fur beneath it.

A collar covers and protects this warm strip of skin from casual brushing.

Check under the front legs (armpits) and between the back legs (groin).

Both are warm, protected, thin-fur zones ticks favor.

Check between the toes, both top and bottom, near the pads.

Easy to miss because it requires spreading the toes apart.

Check around and under the base of the tail.

Another tucked, thin-fur area.

Use your fingertips to feel for a small hard bump at each zone — an attached tick feels like a firm skin-level lump, while an engorged one is larger and softer.

Look for tiny legs near the skin to tell a tick apart from a skin tag, nipple, or scab.

How this calibrates for NH

New Hampshire context

New Hampshire's nymph tick stage peaks mid-May through mid-July and is pinhead-sized — the stage most likely to transmit Lyme disease to people and pets precisely because it's so easy to miss. Going slowly through each hot spot with good light matters most during this window.
