What is the pathophysiology of vasculitis in dogs?
Vasculitis is more often seen in dogs than in cats. Vasculitis can be classified based on the histopathologic appearance: lack or presence of inflammatory infiltrates as well as size and type of vessels involved (small vessel vasculitis, arteritis, phlebitis). However, these classifications do not reliably correlate with a specific etiology.

What is CSVV in dogs?
Cutaneous small vessel vasculitis (CSVV) affects small dermal vessels especially the post capillary venules. CSVV is the most common form of canine cutaneous vasculitis. In dogs, the cellular infiltrate is the most common method used for categorizing the vasculitis.
