QUESTION
If a horse refuses to move unless forced, the lameness is graded as?
OPTIONS
(A) Grade-1
(B) Grade-2
(C) Grade-3
(D) Grade-4
ANSWER
(D) Grade-4
EXPLANATION
According to the Obel grading system for equine laminitis, Grade 4 is the most severe category, in which the horse refuses to move unless forced and may prefer to remain recumbent because of severe hoof pain. In Grade 1, lameness is generally not evident at a walk but a short, stilted gait may appear at a trot; in Grade 2, the horse still walks willingly although the gait is stilted; and in Grade 3, the horse moves very reluctantly and strongly resists attempts to lift a foot. Therefore, a horse that refuses to move unless forced is classified as Grade 4, making option (D) correct.
