What is the hallmark sign of foot-and-mouth disease?

Explanation:
Vesicles and erosions on mucous membranes, especially the mouth and feet, are the hallmark of foot-and-mouth disease. The virus causes fluid-filled blisters that appear on the lips, tongue, gums, and interdigital areas; these vesicles often rupture, leaving painful erosions. This vesicular presentation is the most distinctive feature and is what sets FMD apart from other diseases. Animals commonly show fever and drooling, and lameness from painful mouth and hooves may accompany the lesions. Neurologic signs, respiratory signs, or reddening of the skin can occur with other conditions, but they are not defining for FMD.
