Interdigital Dermatitis is like a wet eczema and has a characteristic bad odour. Infections in the interdigital skin, particularly in the bulb area, cause extra blood circulation in the bulb area. This then causes extra horn formation. The extra horn formation leads to V-shaped splits in the bulb area. This disorder is seen most frequently when the animals are housed inside and exposed to wet conditions.


The disease is a chronic bacterial infection caused by Dichelobacter nodosus. This bacterial species is formerly known as Bacteroides nodosus.
