Why Can’T Dogs Climb Like Cats?

Cats are renowned for their incredible agility and ability to scale walls, trees, and other surfaces with ease. Dogs, on the other hand, generally lack the grace and dexterity that allows cats to climb so effortlessly. But why is this the case? What makes cats such superior climbers compared to their canine counterparts?

In this article, we’ll explore the key anatomical and evolutionary differences between cats and dogs that explain why cats can climb so much better. We’ll look at everything from paw structure to center of gravity to flexibility. Understanding the science behind this climbing divide reveals fascinating insights into how the bodies and abilities of these two common pets have adapted over time. So read on to learn the reasons dogs just can’t keep up with cats when it comes to climbing prowess.

Anatomical Differences

Cats and dogs have several key anatomical differences that enable cats to be agile climbers while limiting most dogs’ climbing abilities. One major difference is in the structure of their front limbs. Cats have very flexible shoulders that allow them to reach up and grip ledges with their front paws easily. Their legs can rotate to allow the elbow to point backward under their body as they climb. Dogs’ front limbs are less mobile, with a more limited range of motion in the shoulder joint (source).

Cats also have semi-retractable claws that give them excellent grip while climbing. Their paws are equipped with flexor tendons that allow the claws to protract or retract as needed. Dogs have claws that do not retract, making it difficult for them to grip surfaces while climbing. Cats’ limb structure combined with retractable claws make them adept at scaling trees, fences, and other surfaces (source).

Shoulder Mobility

Cats have a greater range of motion and flexibility in their front legs and shoulders compared to dogs. This gives cats the ability to reach up and grasp objects more easily. A cat’s shoulder joint can rotate backwards to a greater degree, allowing their front legs to stretch up vertically. Cats can also abduct their front limbs outward from the body to a wider angle.

This extensive shoulder mobility lets cats climb by grasping onto objects above them and pulling their body upwards. As cats stretch their front legs up, their loose shoulder joint and upper arm bone (the humerus) enable the leg to reach up high relative to the body. Cats use their shoulder flexibility to grip and pull on branches, furniture, screens, and more to climb upwards.

In contrast, a dog’s shoulder joint is more restricted and can not rotate backwards as far. The shoulder flexibility in dogs is designed for stability and forward propulsion when running, rather than upward reaching. Limited shoulder mobility makes it challenging for dogs to reach upwards and grip objects above them, hindering their ability to climb like cats.

Grip Strength

Cats have a clear advantage in grip strength over dogs which aids their climbing abilities. Cats have retractable claws that act like built-in climbing hooks, allowing them to grip surfaces securely as they scale walls and trees. Their claws are curved and razor sharp, perfect for digging into bark or concrete. Dogs have blunt nails that don’t provide the same gripping capability.

In addition to their claws, cats have strong forelimbs and leg muscles that give them incredible gripping power. Their front legs are adapted for grasping and holding on tightly. Studies show that cats can exert about 6 times their body weight in gripping force with their front legs. This allows them to hang on as they climb up vertical and inverted surfaces. Dogs simply don’t have the muscular strength in their front legs to match this gripping force.

Cats also have more control over their claws since they can extend and retract them as needed for climbing. Dogs’ claws are always extended, giving them less precision. The combination of razor sharp claws and immense gripping strength from their muscular front legs allows cats to scale surfaces that dogs can only dream of.


Cats are much more agile and flexible than dogs, which gives them a distinct advantage when it comes to climbing. Cats have greater freedom of movement in their spines and shoulders compared to dogs, allowing them to twist, turn, and stretch more easily (Source). Their loose skin and lack of collar bones also enables them to squeeze through very small spaces and fit their bodies into difficult positions.

Additionally, cats have excellent balance and sensory capabilities that aid their agility. They have a keen sense of balance thanks to their vestibular apparatus in the inner ear, which helps them deftly walk along narrow surfaces without falling. Their whiskers also provide sensory information about their surroundings to maintain stability. Cats use their tails to adjust their center of gravity and balancing skills when climbing or leaping. Their light yet muscular frames are built for agility and scaling heights with grace and precision.

Weight Distribution

Cats have a lighter frame and their weight is more evenly distributed across their body compared to dogs. This gives cats an advantage when it comes to agility and climbing. Cats have a flexible spine and their weight is distributed closer to their center of gravity, allowing them to better balance and maneuver their bodies while climbing (see How to shift your weight? – r/bouldering). Their lighter build puts less strain on their limbs as they climb. Dogs tend to be front-heavy, with most of their weight distributed in the front torso and head. This makes balancing and climbing more challenging for dogs.

A cat’s lighter frame and more even weight distribution allows them to nimbly walk along narrow surfaces, quickly change direction, and climb trees and other structures. Their body is designed in a way that facilitates climbing and agility in ways that a dog’s heavier build does not.


Cats and dogs evolved differently due to their environments and roles as predators or prey. Cats are agile climbers thanks to evolutionary adaptations suited for hunting and evading predators in trees and other elevated spaces.

According to a Reddit discussion on cat evolution, cats did not evolve any special abilities solely for climbing trees. Their abilities evolved more broadly for climbing abilities that translated well to trees.

As this Quora post explains, cats likely developed their climbing skills and ability to land on their feet as evolutionary survival mechanisms. Their natural tree-climbing ability helped them hunt prey and evade predators.

In contrast, dogs evolved as social pack animals that did not need to climb trees. Their evolutionary niche favored traits like speed, endurance, and bite strength more than climbing ability.

Brain Structure

Cats and dogs have some key differences in their brain structure that influence their ability to climb. Cats generally have larger brains relative to their body size compared to dogs. According to research, cats’ larger brains relative to their size may enable more complexity and ability when it comes to tasks like climbing.

The cerebellum region of the brain, which coordinates fine motor skills and balance, is also more pronounced in cats. This gives cats superior agility and body awareness when moving in complex ways like climbing. In contrast, the cerebellum region is less developed in dogs, making them less graceful and coordinated for climbing.

In terms of instinct, cats have a strong natural drive to climb vertical surfaces from a young age. Kittens will even climb up curtains or furniture with no training. Dogs do not exhibit the same innate climbing instincts – most need to be trained specifically for climbing tasks. The cat’s brain is essentially wired for climbing from birth.

In summary, cats have brain structures adapted for balance, coordination and innate climbing behaviors that dogs lack. This gives cats a natural advantage for scaling tall objects with grace and ease compared to dogs.


In summary, the key reasons dogs cannot climb trees and other structures as well as cats are due to differences in their anatomy, grip strength, agility, weight distribution, evolution, and brain structure. Dogs’ front limbs are not as mobile and flexible as cats’ due to differences in their shoulder joints and muscles. Dogs also lack the sharp gripping claws that cats use to cling to surfaces. Cats are more agile and flexible due to their lighter build and limbs that can rotate in almost any direction. Their lighter weight also allows cats to navigate narrow branches. Evolutionary differences shaped dogs for chasing prey on the ground while cats adapted for climbing to escape threats. Finally, neurological differences give cats superior balance and coordination for climbing compared to dogs.

While dogs can climb short distances and some breeds are capable climbers, they lack many of the physical and neurological adaptations that make cats such adept climbers. The evolutionary paths of cats and dogs produced key differences that enable cats to excel at climbing trees and scaling structures while dogs are better suited for running and hunting prey on the ground.
