Canine locomotion, the movement of our beloved four-legged companions, is a complex ballet of muscles, bones, and joints working in harmony. While casual observers, even dog owners might merely see ‘a dog running,’ the reality is a series of finely-tuned biomechanical actions. 

Let’s delve into the intricacies of the canine gait, the variation between breeds, and why understanding these movements is crucial for health assessments.

Basics of Canine Locomotion

Locomotion, particularly in mammals like dogs, is a complex process involving coordination between the nervous system, skeletal structure, and muscular systems. 

As we dive deeper into the basic gaits of dogs, we’ll appreciate the intricate synchronisation and efficiency of their movement.


The walk is a rhythmic, four-beat gait that exemplifies energy conservation.

Footfall Sequence: Typically, a dog starts walking with the lift of its front left foot, followed by the rear left, then the front right, and finally the rear right.

Body Mechanics: The body remains relatively level during walking. The head might bob a little, which is an adjustment for balance and momentum.

Usage: This gait is used for exploration, leisurely strolls, or when conserving energy is more essential than speed.


The trot is both graceful and efficient, covering ground at a moderate pace.

Footfall Sequence: In the trot, diagonal pairs of legs move in unison. The front left and rear right strike the ground simultaneously, followed by the front right and rear left.

Body Mechanics: A trot is more energy-intensive than a walk, but it provides the advantage of speed without a significant expenditure of energy. The dog’s back remains relatively horizontal, although there’s more vertical movement than in walking.

Usage: Trotting is often seen when a dog is on a focused path, perhaps following a scent or patrolling its territory.


A canter exhibits more energy and is commonly seen during play or quicker navigation.

Footfall Sequence: The sequence starts with one hind leg pushing off (let’s say the left), followed by a simultaneous grounding of the right hind and left front, and then the right front. This results in a “rocking horse” movement.

Body Mechanics: The back shows a more pronounced arch during each stride, and there’s an evident lift of the dog’s hindquarters. The head and neck extend forward during the lead leg’s grounding.

Usage: Often seen in playful runs or when a dog is in a hurry but not in full chase mode.


This is the fastest gait, characterised by maximum speed and effort.

Footfall Sequence: Galloping involves two phases. In the ‘double suspension’ gallop, there are two instances when all four feet are off the ground—once when the legs are fully extended and once when they’re tucked under the body.

Body Mechanics: The spine flexes and extends significantly, allowing for the maximum distance covered per stride. The head is usually low, and the line of sight is forward and focused.

Usage: Employed during high-speed chases or when escaping a perceived threat.

Breed Specific Gait Variations

While the fundamental biomechanics of canine movement remains consistent across breeds, the specifics of gait can vary. For instance:

Dachshunds, with their long bodies and short legs, often have a more pronounced lateral movement when they trot.

Greyhounds, built for speed, have a flexible spine that allows for a significant stretch when they gallop, maximising their stride length.

Mastiffs and other large breeds, due to their size and weight, may have a more lumbering gait, moving with power but less agility than smaller breeds.

The variation in gait between breeds often ties back to their historical purpose. For example, an advantage of Golden Retrievers is that they are known for having agile, nimble gaits allowing quick changes in direction, while sled dogs like Huskies have a strong, enduring trot optimised for long distances.

Gait as a Health Indicator

Understanding the biomechanics of the canine gait isn’t just an academic exercise; it’s a vital tool for assessing a dog’s health. Anomalies in gait can be early indicators of a range of health issues:

  • Orthopaedic Issues: A limp, favouring a leg, or hesitancy in movement can signal problems like hip dysplasia, arthritis, or fractures.
  • Neurological Disorders: An unsteady gait, knuckling of the paws, or dragging feet can be signs of conditions like degenerative myelopathy or other neurological disorders.
  • Muscular Disorders: If a dog seems to tire easily or has a stilted movement, it might be facing muscular issues or conditions like myasthenia gravis.

Regularly observing and understanding a dog’s gait can help in early detection of such conditions, facilitating timely intervention and better prognosis.


The dance of muscles and bones that results in a dog chasing its tail, running after a ball, or merely trotting beside its owner on a quiet morning walk is a marvel of nature’s engineering. By better understanding the biomechanics of the canine gait, not only do we deepen our appreciation of these beloved animals, but we also equip ourselves to ensure their health and well-being for years to come.
