Most incidents with horses are not sudden. They are not caused by disobedience or stubbornness. They are the predictable result of humans missing what the horse was communicating long before any behaviour occurred.
The 60-second scan is a simple but powerful skill. It teaches you to pause, observe and understand the whole horse before adding touch, pressure or intention. When you understand the state a horse is in, you handle them more safely, communicate more clearly and prevent conflict.
This is not about diagnosing medical problems. It is about reading the animal in front of you through a full-spectrum lens. A horse’s behaviour comes from their nervous system, pain levels, posture, hormones, gut health, hoof comfort, sleep quality, metabolism, environment, herd dynamics, sensory thresholds, previous experiences and the human’s presence.
This is the whole horse. Not just the behaviour.
The Five Core Layers You Must Read
A horse’s presentation is expressed across five interconnected layers:
1. The nervous system
2. The body and posture
3. The environment and sensory load
4. The herd or social context
5. The internal state, including pain, hormones, gut health, hooves, sleep and history
Reading only one layer is why people misinterpret horses.
Start Your 60 Seconds
You are not judging the horse. You are assessing their capacity.
The guiding question is:
What is the horse experiencing right now, and do they have capacity for what I am about to ask?
1. Eyes: The Fastest Window into the Nervous System
Observe:
• brightness or dullness
• soft or hardened expression
• blink rate
• tension around eyelids
• scanning or hypervigilance
• fixed or glassy stare
• half closed eyes indicating fatigue or discomfort
Soft eyes and regular blinking often reflect regulation.
Hard eyes or fixed gazes show sympathetic activation or dorsal shutdown. Scanning indicates sensory overload.
Half closed eyes often reflect pain or exhaustion, not relaxation.
2. Facial Expressions and Micro Tension
The face communicates internal pressure long before behaviour does.
Look for:
• tight muzzle
• lips pressed together
• nostrils drawn or vertical
• jaw tension
• wrinkles around eyes or muzzle
• chewing without food
• tongue tension
• tremors near nostrils or chin
Facial tension is one of the most reliable early indicators of activation or discomfort.
3. Posture and Movement Integrity
Posture is shaped by the nervous system, muscles, joints, hooves, pain, emotional state and history.
Observe:
• leaning forward or back
• braced or hollowed back
• tension in shoulders
• ribs lifted or collapsed
• uneven stance
• reluctance to step forward
• hesitancy to turn
• asymmetrical movement
• rigidity or heaviness
Sympathetic activation shows in rigidity and readiness to move.
Dorsal collapse shows in heaviness or shutdown. Pain appears as guarding, shortening, crookedness or compensation.
Movement never lies.
4. Pain Indicators
Pain changes thresholds, behaviour and regulation. It must be considered first.
Equine Pain Face
• tension above the eye
• triangular shape around the orbit
• fixed or half closed eyes
• tightened muzzle
• strained nostrils
• stiff or drooping ears
• chin pulled tight
Movement and body indicators
• toe first landings
• short, stilted strides
• difficulty turning
• head bobbing
• reluctance to move forward
• stumbling
• repeated weight shifting
• tail off centre
Behavioural indicators
• defensiveness during grooming
• irritability
• withdrawal
• shutdown that looks like compliance
• difficulty being caught
• loss of appetite
• unpredictable reactivity
Pain often masquerades as disobedience.
5. Hormonal Influences
Hormones affect sensitivity, thresholds and social behaviour.
Mares
Estrus cycles may create:
• irritability
• abdominal or back sensitivity
• difficulty concentrating
• reluctance for hindquarter pressure
• changes in appetite or movement
Geldings
Some retain hormonal patterns that influence:
• boundary-setting
• reactivity
• seasonal energy shifts
Stallions
Highly responsive to herd dynamics, novelty and proximity to mares.
Hormonal context shapes behaviour.
6. Metabolic Conditions and Internal Physiology
(EMS, PPID (Cushing’s), insulin resistance)
Metabolic strain affects:
• thresholds
• mood
• energy levels
• soundness
• foot comfort
• inflammation
• appetite
• coat changes
Behaviour often reflects physiological stress rather than training issues.
7. Gut Health and Digestive Comfort
The gut and nervous system are deeply connected.
Signs of gut discomfort include:
• teeth grinding
• flank sensitivity
• stretching posture
• inconsistent grazing
• restlessness while eating
• abdominal tension
• frequent stopping and starting
Digestive discomfort can create reactivity, avoidance and irritability.
8. Sleep Quality
Sleep deprivation destabilises behaviour and regulation.
Indicators include:
• standing sleep without lying down
• catching themselves while dozing
• excessive yawning
• hind end weakness when resting
• stumbling from fatigue
• puffiness above eyes
• reluctance to lie down due to pain or herd pressure
A sleep deprived horse cannot regulate effectively.
9. Hoof Comfort and Movement Integrity
Hoof discomfort cascades through the entire body.
Look for:
• heel avoidance
• toe first landings
• stiffness in shoulders
• reluctance on hard ground
• uneven gait
• short stepping
• postural compensation
• difficulty turning
Foot pain is one of the most common hidden causes of tension.
10. Dental Discomfort and Oral Pain
Dental issues are a major but often overlooked driver of behaviour.
Look for:
• difficulty chewing
• dropping or packing food
• undigested fibres in manure
• head tilting when eating
• resistance to bridling
• opening the mouth or gaping
• head tossing
• reluctance to lower the head
• hypersensitivity to noseband or poll pressure
• jaw tension
• excess salivation or dry mouth
• quidding (dropping partially chewed hay)
Common causes include sharp points, hooks, ramps, retained wolf teeth, ulcers and bit interference.
Oral pain often shows up as:
• reactivity
• anxiety
• head-related tension
• poll resistance
• sudden training issues
A complete scan must consider dental discomfort.
11. Medication and Supplement Effects
A horse’s presentation may be altered by substances they receive.
Consider:
Pain medications
May mask underlying discomfort.
Sedatives and calmers
Suppress behaviour without lowering internal stress.
Sedation can look like calm but is not regulation.
Prascend for PPID (Cushing’s)
May change mood, energy and appetite.
Digestive supplements
May alter comfort levels and demeanour.
Always know what the horse is taking.
12. Recent Changes and Context Shifts
Sudden behaviour changes often reflect environmental or routine shifts.
Consider changes in:
• feed or forage
• turnout time and space
• herd members or hierarchy
• routines or handlers
• location or yard
• tack or equipment
• weather
Most behavioural change has a reason.
13. Sensory Load and Processing Style
Horses differ widely in sensory thresholds.
Look for:
• ear flicking
• skin twitching
• startle patterns
• hyper-awareness
• fixation on sounds or movement
• difficulty filtering noise
Highly sensitive horses reach overload faster.
14. Weather, Seasons and Atmospheric Shifts
Weather affects physiology and behaviour.
Heat can cause fatigue and irritability.
Cold can create stiffness and bracing.
Storms, pressure drops and wind heighten alertness.
Seasonal transitions shift hormones, forage, metabolic stress and herd behaviour.
Environmental pressure is real.
15. Herd Dynamics
A horse is part of a social system.
Observe:
• who they seek
• who they avoid
• separation stress
• guarding or blocking
• agitation when a partner leaves
• shifts in social order
A horse’s emotional state is inseparable from herd behaviour.
16. Age and Development
Age shapes capacity.
Young horses
Neurobiologically immature. Expect:
• quick state-switching
• low impulse control
• sensory overwhelm
• inconsistent attention
• developing proprioception
Senior horses
Often experience:
• stiffness
• reduced senses
• slower processing
• higher fatigue
• metabolic strain
Understanding life stage prevents unrealistic expectations.
17. Breed and Type Tendencies
Different breeds express stress differently.
Examples:
• Arabians show activation visibly and quickly.
• Thoroughbreds have high sensory sensitivity.
• Warmbloods may internalise tension.
• Quarter Horses can mask stress subtly.
• Ponies often show metabolic-driven behaviours that look like stubbornness.
Breed context matters.
18. Trauma History and Learned Patterns
History shapes behaviour.
Look for:
• pre-emptive flinching
• avoidance before touch
• bracing at equipment
• defensive patterns
• shutdown mistaken for calm
• tension in predictable scenarios
These are survival strategies.
19. The Human Field
Your state influences the horse.
A horse reads:
• breath
• heart rate
• posture
• micro-movements
• emotional tone
• intention
• energetic field
A dysregulated human creates uncertainty. A regulated human offers safety.
The Decision Point
After your 60-second scan, ask:
Does this horse have the capacity to connect, learn or engage right now?
If the answer is no, you do not proceed with your agenda.
You pause. You regulate. You adapt to the state of the horse.
This is how accidents are prevented.
This is how trust is built.
This is horsemanship rooted in biology, compassion and accuracy.
This is the Whole Horse Journey.
