Ear tip necrosis can be seen in cases of canine hyperadrenocorticism, particularly in breeds with small thin ear pinnae. The cause is unknown, but it may be related to micro thromboembolisms. <br><br>

Animals with hyperadrenocorticism bruise easily and the skin becomes thinner, possibly contributing to the development of these lesions. Finally, high concentrations of circulating glucocorticoids may affect healing of the lesions.

Familial vasculopathy has been reported in young German shepherd dogs. It is inherited via an autosomal recessive trait, and affected dogs develop alopecia, crusts, and ulceration of the ear tips. Depigmentation and crusting of the footpads may be seen along with lethargy and pyrexia (Ferguson, 2002).
