Foot rot can be a very annoying problem.
Although the incidence of foot rot may not be high at any one time, it requires constant observation to prevent serious economic loss. A specific bacterium invades the foot to cause the disease. Cuts, bruises, puncture wounds, or severe abrasions permit these bacteria to enter the tissue of the foot where they start an infection. Foot rot can be a seasonal disease, occurring during periods of extreme moisture, sudden freezing of muddy yards, or severe drought. The first observed sign of foot rot is lameness, which may vary from scarcely noticeable to severe in one or more feet.
