Episodic falling syndrome (EFS)

Episodic falling syndrome (EFS) in Cavalier King Charles spaniels is a canine paroxysmal hypertonicity disorder. Episodes begin between fourteen weeks and four years of age and are triggered by exercise, stress, apprehension or excitement. Episodes are characterized by progressive hypertonicity throughout the thoracic and pelvic limbs, which can lead to immobilization and collapse. Other clinical signs may include facial muscle stiffness, stumbling, a 'bunny-hopping' gait and arching of the back.
