in domestic equines.

KNOW THE INDIVIDUAL

Pain is best recognized by change from normal.

Validated equine pain tools combine facial expression, behavior and movement. No single scale fits every condition, and an owner should use a tool with veterinary guidance rather than treating a score as a diagnosis.

Observe the whole animal

  • Fixed or backward ears, orbital tightening or a tense muzzle
  • Reduced appetite, slower chewing or altered drinking
  • Isolation, lowered head, unusual stillness or reduced response
  • Repeated weight shifting, guarding a limb or reluctance to turn
  • Shortened stride, stiffness, reduced performance or difficulty rising
  • Pawing, flank-watching, rolling, sweating or repeated lying down

Create information the veterinarian can use

  • Record short videos at rest, walking straight and turning when safe.
  • Note appetite, manure, sleep, herd interaction and willingness to move.
  • Compare the same activities at similar times each day.
  • Use a veterinarian-selected pain scale consistently.
  • Do not mask worsening signs by changing medication without instructions.

Do not wait for dramatic behavior

  • Colic signs or inability to pass manure
  • Sudden severe lameness or inability to bear weight
  • Strong digital pulses, hoof heat or a laminitis stance
  • Difficulty breathing, collapse or neurologic signs
  • A donkey that stops eating or becomes markedly quiet

Treatment should address the cause

Pain plans may include veterinary medication, hoof or dental treatment, rehabilitation, body-condition management, environmental changes and treatment of underlying disease.

Important: Never copy a medication or dose between a horse, donkey and mule without direct veterinary instruction.
