You’re out on a trail in the Cascades or maybe just wandering through a muddy patch in your own backyard in Ohio. You look down. There’s a smudge. A press of toes. A heavy heel. Most people see a blur and think "dog" or "deer" and keep walking, but North American animal footprints are basically a high-stakes diary written in the dirt. If you know how to read them, the forest stops being a wall of green and starts being a crowded room.
Honestly, identification is harder than the guides make it look. You see those perfect, crisp illustrations in field books? Nature doesn't work like that. Real tracks are messy. They’re filled with water, squashed by pine needles, or stretched out because the animal was hauling tail away from a predator. To actually get this right, you have to stop looking at the shape and start looking at the "stride" and "straddle."
The Dog vs. Cat Dilemma
This is where everyone messes up. You find a big, four-toed print and immediately think "Mountain Lion." It’s usually a neighbor's Golden Retriever. But there’s a trick.
Coyote and dog tracks almost always show claw marks. Why? Because canids can't retract them. They need that traction for long-distance running. Felines—like bobcats and cougars—keep those claws tucked away to keep them sharp for the kill. If you see claws, think dog. If the toes look like clean, teardrop-shaped ovals with no nails, you're likely looking at a cat.
But wait. There’s more to it. Look at the "heel pad" (the big squishy bit at the bottom). A dog’s heel pad has one lobe on the top. A cougar’s heel pad has a distinct "M" shape or two indentations on the top edge. It’s a subtle anatomical difference that saves you from calling the park ranger over a stray Lab.
Why the "Perfect Print" is a Myth
Mud is a liar.
If a 200-pound Black Bear steps in deep, saturated silt, the mud collapses inward as the foot lifts. This makes the track look smaller and narrower than it actually is. Conversely, if the sun hits a track in the snow, the edges melt and expand. Suddenly, that squirrel track looks like it belongs to a Wolverine.
Expert trackers like Mark Elbroch, author of Mammal Tracks & Sign, stress that you have to look at the "trail pattern." How is the animal moving?
- Walkers/Trotters: Deer and coyotes move their legs in a rhythmic, alternating fashion.
- Bounders: Weasels and minks jump, landing their front feet and then placing their back feet exactly where the front ones were.
- Hoppers: Rabbits and squirrels. Their big back feet actually land ahead of their front feet.
It’s counterintuitive. You’d think the front feet lead the way, but when a Jackrabbit is mid-bolt, those massive powerful hind legs swing past the front ones. If the "big" prints are in front of the "small" ones, you’re looking at a hopper.
Bears and the Human Mimicry
Black bear tracks are eerie. The hind print looks shockingly like a flat-footed human footprint. If you’re hiking in the Smokies and see what looks like a barefoot person with five toes and a very wide heel, don't go looking for a lost hiker. Look for the claw marks. Bear claws on the front feet are usually longer than the toes themselves, used for digging up grubs and tearing apart rotted logs.
The "Little Human" prints, though? That’s the Raccoon. Their front paws look like tiny, sensitive hands. They have five long, slender toes that they use to manipulate objects, wash food, and pick locks on "bear-proof" trash cans. If you see a track that looks like a baby’s handprint next to a creek, it’s almost certainly Procyon lotor.
The Geometry of a Deer Track
Deer tracks are the bread and butter of North American animal footprints. They’re everywhere. Two pointed toes forming a heart shape. Simple, right?

Sorta.
When a deer is walking slowly on firm ground, the two hooves stay tight together. When they’re spooked and sprinting, the hooves splay wide to create more surface area. You might also see two small dots behind the main hoof. Those are "dewclaws." Many people think only heavy elk or moose leave dewclaws, but a White-tailed deer will leave them too if the mud is soft enough or if they’re jumping.
Mud, Sand, and Snow: The Context Matters
Tracking is 10% biology and 90% physics.
In the Southwest, sand is your enemy. It’s too grainy to hold fine detail. You won't see the tiny "interdigital pads" of a Grey Fox. You’ll just see a series of depressions. In the North, "crusty" snow can support the weight of a Lynx but not a Bobcat. The Lynx has massive, furry paws that act like natural snowshoes—their footprint is huge relative to their body size, preventing them from sinking.
If you find a massive feline track in the Montana snow that seems way too big for a 30-pound cat, check the depth. If it’s sitting on top of the powder, it’s a Lynx.
Quick Identification Shortcuts
- Negative Space: Draw an "X" through the middle of the track. If the lines pass through the heel pad, it’s a dog. If they don't, it’s a cat.
- The Number of Toes: Most mammals have five on the back and four on the front, or five and five. If you see four and four, think canid, feline, or deer (hooves).
- The Direction of the "V": In a deer track, the points of the heart aim the direction the deer is traveling.
Common Mistakes and How to Avoid Them
Don't be the person who calls a 3-inch dog print a Wolf. Gray Wolves are ginormous. Their tracks are often 5 inches long—basically the size of an adult man’s hand. Unless you are in the deep wilderness of the Northern Rockies, the Great Lakes, or Alaska, it’s probably a large domestic dog.
Also, watch out for "double registering." This happens when an animal steps with its hind foot directly into the print left by its front foot. This is a survival tactic. It minimizes noise and saves energy. To an untrained eye, it looks like one weirdly shaped, elongated footprint. To a tracker, it’s a sign of a focused, efficient traveler like a Coyote or a Fox.
Real-World Tracking Tools
You don't need a lab. You need a ruler and a camera. Always place an object for scale next to a track before you photograph it. A coin works, but a standard 6-inch ruler is better. Take the photo from directly above, not at an angle. The "raking light" of early morning or late afternoon is best because the long shadows pop the edges of the track, making the details visible.
If you’re serious about this, carry a small clear plastic sheet and a sharpie. Lay the plastic over the track and trace the outline. It’s an old-school technique that teaches your brain to see the actual edges rather than what you expect to see.
Actionable Steps for Your Next Hike
To improve your identification skills today, start with these three habits:

- Check the Perimeter: Don't just stare at one print. Follow the "trail" for 20 feet. The way the animal moves (the gait) tells you more than the shape of a single toe ever will.
- Measure the Width: Carry a small tape measure. A Coyote track is narrower than a domestic dog’s. A dog’s toes splay out because they don’t have to worry about snagging them on brush; a wild canid keeps its feet "tight" and efficient.
- Learn Your Locals: Search for a "local mammal list" for your specific county. Knowing that Wolverines don't live in Florida prevents you from making an embarrassing misidentification of a messy Badger or Raccoon track.
Focus on the heel pads and the negative space first. Once you master the difference between the "M" shape of a cat and the "lobed" shape of a dog, the rest of the forest starts to make a lot more sense.
