Dorsal nasal alopecia, alpaca
Dorsal nasal alopecia, alpaca

    Photograph of an alpaca with alopecia over the dorsal bridge of the nose. This may be due to rubbing, such as due to pruritus from ectoparasite activity and seems over-represented in dark-haired animals (hence the name dark nose syndrome).
