The mighty brown bear lumbers through the forest on four massive yet nimble paws. If you’ve ever wondered how these powerful predators use their front and hind paws, you’ve come to the right place.
If you’re short on time, here’s the key point: brown bears rely heavily on their versatile front and back paws for walking, running, climbing, digging, catching prey, and more.
In this comprehensive guide, we’ll explore everything you ever wanted to know about brown bear paws, from their anatomy and features to the remarkable ways brown bears use them in the wild.
Anatomy of Brown Bear Front and Hind Paws
Paw Size and Shape
Brown bears have very large front and hind paws compared to other bear species. Their front paws are broader and measure around 15-20 cm across, while the hind paws are longer and narrower at 20-25 cm (Smithsonian’s National Zoo & Conservation Biology Institute, 2022).
This gives them a plantigrade stance where the entire paw rests on the ground when walking.
The enlarged size and spread-out toes on the front paws in particular help brown bears to grip and hold food items. For example, salmon trying to swim upstream or roots and berries picked from the forest floor. The curved, robust claws further aid this grip strength.
Claws
All brown bears have five toes on each front and hind paw, with thick, non-retractable claws up to 10 cm long growing from each digit (Kodiak Brown Bear Center, 2022). The claws are ideal tools for digging up the soil to access small mammals like marmots, tearing apart logs to reach insects inside, and hooking salmon from the water.
Since the claws are always exposed, they become blunted through continual daily use. To keep them sharp, brown bears have evolved the instinct to rub and whet their claws against hard surfaces like trees and rocks. This filing action wears down weak outer layers to reveal the pointed claw underneath.
Paw Pads
Thick fur covers the tops of brown bear paws, while leathery skin makes up the undersides forming the weight-bearing surface. Strategically placed paw pads provide cushioning and traction when walking on a variety of surfaces from snowy slopes to muddy riverbeds (Katmai National Park, 2022).
There are five digital pads underneath each toe that act like shock absorbers. Plus a large central metacarpal or metatarsal pad behind the digits. The rippled texture and skin folds on the pads improve grip, aided by smooth sections that allow flexibility.

How Brown Bears Use Their Front Paws
Walking and Running
A brown bear’s front paws play a key role in walking and running. Their paws have five strong claws that help propel them forward with each step. When walking, the bear places its full foot on the ground, spreading its toes widely apart to distribute weight evenly.
While running, the bear lifts itself up on its toes in a bounding gait. This galloping movement allows the heavy bear to quickly accelerate to speeds of 30 miles per hour for short bursts.
Climbing
A brown bear’s non-retractable claws also enable it to be an expert climber. Bears use their curved claws to grip bark and scale trees with ease. This ability allows them to escape danger, access food sources, and reach vantage points. Mother bears teaching cubs to climb trees is an adorable sight!
The huge paws provide excellent traction on trunks and branches.
Digging
Those sizable paws come in handy for digging, too. Brown bears employ their long claws and powerful front limbs to dig dens for hibernation and birth, excavate roots and tubers to eat, and uncover rodents and insects from logs and soil.
Their robust shoulder muscles and thick forelimbs allow them to dig holes rapidly. One amazing video captured a bear digging a massive crater in about 15 minutes!
Hunting and Fishing
Bears rely heavily on their front paws for hunting and fishing. They use their dexterous paws to pin down prey like salmon, tear apart logs to find insects, and flip over rocks to uncover rodents. The paws are equally nimble in the water, enabling the bear to snatch darting fish.
One viral photo sequence showed a bear’s quick paw actions in catching a jumping salmon in the blink of an eye!
Defense and Territorial Marking
Those strong, clawed front paws also serve bears well in defense and marking territory. Bears will take a swipe with their paws as a warning sign when defending cubs or food. They also scrape trees and the ground with their claws to leave visual and scented markers.
Interestingly, bears are generally right pawed in defense and left pawed in marking. Who knew bear paws could be so multi-talented!
How Brown Bears Use Their Hind Paws
Providing Propulsion and Speed
A brown bear’s large and powerful hind paws give them the ability to stand and move quickly. Their hind legs and paws make up about 2/3 of their height and provide tremendous force to propel them in bursts up to 35 mph, enabling them to chase down prey or escape danger with haste (1).
The heavy musculature and wide paws make them adept at digging as well, allowing access to underground food sources like rodents and roots.
Standing Up
Bears have remarkable flexibility and balance, frequently standing upright on their hind legs. They stand to get a better view of their surroundings, and will often cautiously rise to sniff the air when detecting something unfamiliar.
Mother bears protecting their cubs may stand tall to appear more imposing to perceived threats. Dominant mature males stand and posture to establish rank and superiority over other bears.
Scratching
A bear’s back can get quite itchy, especially when new fur is growing in. Fortunately, their flexible legs and sharp claws allow them to satisfy those hard-to-reach spots. Watching a bear stand with one leg lifted to vigorously scratch while enjoying a good back-scratch is quite a sight (and something many humans might envy!).
By biting and pulling with their teeth, and bracing on a tree, they can also stretch and scratch other hard to reach places like their hips and shoulders.
Defense
Though bears typically avoid conflicts, their strong hind legs and deadly claws make formidable weapons if needed. With muscles enabling 800lbs of pressure per swipe, a bear can easily fell trees and break bones (2).
Few creatures dare tangle with an angry bear rearing up to deliver devastating blows with its hind paws. And if needed to keep themselves or their cubs safe, they can quickly turn and race off at high speeds on their muscular legs.
A brown bear’s flexible and muscular back legs provide speed, balance, leverage for scratching, and formidable defense to protect it in the wild.

Conclusion
As we’ve explored, brown bears rely extensively on their versatile paws for moving, manipulating their environments, catching prey, and more. Their front and hind paws work together seamlessly to help brown bears dominate their habitats.
The next time you see a lumbering brown bear, take a moment to appreciate the remarkable anatomy and capabilities of its hard-working paws!
