Why animal tracks are worth reading
Most wild animals avoid us, so we rarely see them. Their tracks, however, stay behind for hours or even days. A muddy creek bank can show who drank there last night. It can even show which way the animal went.
That is why I love animal tracks. They turn a quiet walk into a detective story. I built this identifier around 24 common and well-known tracks from Canada and the United States. They range from deer and coyotes to raccoons, beavers and herons.
Every print in the tool is a clean drawing, not a photo. Real tracks are messy, so the drawings show only the features trackers rely on: toes, claws, pads and size.
How to identify animal tracks in four steps
Count the toes
Hooves show two halves. Dogs, cats and rabbits show four toes. Bears, raccoons, opossums, skunks, beavers and otters have five. Squirrels and porcupines show four in front and five behind.
Look for claws
Dog-family tracks usually show claw tips. Cats keep their claws pulled in, so their tracks rarely show any.
Measure the length
Measure from the back of the heel pad to the tip of the longest toe, leaving out claws. Measure a few prints and use the average. The bear sizes in the tool include claw marks.
Follow the trail
The pattern of prints shows how the animal moves. A neat line suggests a deer, fox or cat. Groups of four suggest a rabbit or squirrel.
Each step removes a big group of suspects. The toe count alone narrows 24 animals to a handful. After that, size and trail pattern usually finish the job.
The main track families
Most of the 24 tracks in this tool fall into eight groups. The porcupine is the odd one out, so look for its pebbly sole. Tap any card to open that animal in the identifier above.
Dog tracks vs cat tracks
This is the classic tracking question, and two quick checks answer it. First, look for claws. Then, look at the overall shape.
| Feature | Dog family (coyote, wolf, fox, dog) | Cat family (bobcat, cougar, house cat) |
|---|---|---|
| Shape | Oval, longer than wide | Round, about as wide as long |
| Claw marks | Usually show (gray foxes can hide theirs) | Rarely show |
| Toes | Symmetrical; the two front toes sit level | Asymmetrical; one toe leads, like our middle finger |
| Heel pad | Smaller, with one lobe at the front | Large, with two lobes at the front and three at the back |
| Trail | Wild canids travel in straight lines; pet dogs wander | A neat line; the hind foot often lands in the front print |
Common look-alikes and how to split them
Some pairs fool almost everyone. Use the compare buttons on each card in the tool, or check this table.
| Look-alikes | The check that splits them |
|---|---|
| Coyote or dog | Coyote tracks are narrow and neat, with sharp claw tips and a straight trail. Dog tracks are rounder, with splayed toes and a wandering trail. |
| Bobcat or house cat | Measure it. A house cat’s front track is about 1½ in (3.8 cm) long or less. A bobcat’s is bigger. |
| Black bear or grizzly | Grizzly toes sit in a nearly straight row, with claw marks far ahead. Black bear toes form a curved arc. |
| Raccoon or opossum | An opossum’s hind thumb sticks out sideways. A raccoon’s fingers all point forward. |
| Deer or elk | Adult elk tracks are bigger, usually about 4 in (10 cm) long or more, and rounder. Deer tracks are smaller and more pointed. |
| Cottontail or snowshoe hare | A hare’s hind print can reach 6 in (15 cm). A cottontail’s stays at about 3 in (8 cm) or less. |
| Beaver or otter | A beaver’s webbed hind print is about 5 to 7 in (12 to 18 cm) long, roughly twice an otter’s. Beavers also leave tail drags. |
How to measure and photograph a track
- Length: measure from the back of the heel pad to the front of the longest toe. I leave claws out, but some field guides include them, so note which way you measured.
- Width: measure across the widest part of the print.
- Stride: measure from the front of one print to the front of the next print made by the same foot. Some field guides measure from one print to the next instead, so check which one a guide uses.
- Photos: shoot straight down, with a ruler or coin beside the print. Then take a second photo of the whole trail.
Watch out for melting snow. Sun and warmth enlarge tracks in snow, and soft mud spreads them too. Measure the bottom of the print, not its rim, and average several prints.
Where and when to find animal tracks
Soft mud, damp soil and sand hold the clearest prints. Creek banks, lake shores and the edges of puddles after rain are great places to start. Wet snow also holds crisp tracks, while dry powder only shows vague outlines.
Timing matters as well. Many mammals move at dusk and at night, so early morning is the best time to look. Low morning light also helps, because shadows fill each toe and pad. If you want to know who walks around after dark, my guide to nocturnal animals is a good next read.
Finally, look for other signs beside the tracks. Scat, chewed sticks, rubbed bark and fur caught on fences all add to the story.

Animal tracks FAQ
How do I identify animal tracks?
Start with the toe count, then check for claw marks. Next, measure the length from heel pad to longest toe. Finally, follow the trail to see the pattern of prints. Those four clues narrow most tracks to one or two animals.
What animal has four toes and no claw marks?
Usually a member of the cat family, such as a bobcat, mountain lion or house cat. Cats keep their claws pulled in while they walk. Rabbit tracks can also lack clear claws, because fur blurs their feet. Gray foxes can pull in their claws too.
How can you tell a coyote track from a dog track?
A coyote track is a narrow, neat oval with sharp claw tips. Dog tracks are usually rounder, with splayed toes and blunt nails. Coyote trails also run straight, while dog trails wander.
Which animal tracks look like a human footprint?
A bear’s hind print looks like a big, flat human footprint, because bears walk flat-footed like us. Raccoon tracks look like tiny human hands.
Which animal leaves the biggest tracks in North America?
Bears do. A grizzly’s hind print, claws included, can reach about 14 in (36 cm). Moose leave the biggest hoof prints, and great blue herons leave some of the longest bird tracks.
Why do tracks in snow look bigger than they should?
Sun and warm air melt the edges of a print, so it slowly grows. Soft mud spreads too. Measure the bottom of the print, not its rim, and check several prints.
