Abstract
A high incidence of necrotizing vasculitis was observed in 9 individuals from a group of 32 Beagle dogs. The clinical, biochemical, haematological and pathological features of the disease are described and the possible aetiology discussed. This condition has not been seen in other animals from the same breeding stock either before or since the outbreak and it is of some concern that such a cluster of cases could reappear in the future.
