why do horses bury food

The Deep Dive

The idea that horses bury food stems from a misunderstanding of their natural behaviors. Horses are hindgut fermenters with relatively small stomachs, designed to process a near-constant stream of fibrous plant material. Unlike squirrels, dogs, or certain bird species that cache food for lean times, horses evolved on open grasslands where grass was generally abundant year-round. There was no evolutionary pressure to develop food-storage behaviors. What people sometimes observe and interpret as burying is actually pawing. Horses paw the ground for several reasons: to uncover grass buried under snow during winter, to dig at roots or mineral-rich soil, or to signal frustration or boredom in confined environments. In stabled horses, bedding material may accidentally get tossed over feed, creating the illusion of intentional burial. Another related behavior is scraping or nudging feed with their muzzle, which is simply sorting or selecting preferred bits rather than hiding them. Horses also sometimes refuse to eat soiled or trampled hay, which might be misread as them having buried and rejected it. The key distinction is intent: food-caching animals deliberately store provisions for future consumption, while horses simply interact with their environment in ways that can superficially resemble caching. Their entire physiology, from their continuously growing teeth to their massive cecum for fermenting fiber, points to an animal built for constant grazing, not strategic hoarding.

Why It Matters

Understanding that horses do not bury food has practical implications for equine care. Owners who believe their horse is caching food may misinterpret pawing or feed-sorting behaviors, potentially missing signs of colic, boredom, or nutritional deficiency. Recognizing pawing as a communication signal helps caretakers respond appropriately to a horse's physical or psychological needs. This knowledge also informs proper feeding practices: horses thrive on slow, steady access to forage rather than large discrete meals, and mistaking natural grazing behaviors for food-burial instincts could lead to inappropriate feeding schedules. For veterinarians and equine behaviorists, distinguishing between genuine behavioral anomalies and normal species-typical actions is essential for accurate diagnosis and welfare assessments.

Common Misconceptions

The most widespread myth is that horses bury food the way squirrels bury acorns or dogs bury bones. This is entirely false. Horses lack both the instinct and the anatomical tools for food caching. A second misconception is that when a horse paws at its feed pile or covers grain with bedding, it is intentionally saving the food for later. In reality, this is usually accidental displacement or exploratory behavior. Horses investigate feed with their sensitive lips and muzzle, pushing and sorting it, which can scatter material. If bedding covers food, it reflects the horse's environment, not a deliberate storage strategy. Confusing these behaviors with caching can lead owners to overlook genuine behavioral concerns.

Fun Facts

• A horse's stomach holds only about 2 to 4 gallons, which is why they evolved to eat almost continuously for up to 16 hours a day.
• Horses cannot vomit due to a powerful cardiac sphincter muscle, making proper feeding practices especially critical for their digestive health.
