Pseudorabies virus (PrV) can persist within the wild boar population allowing them to be potential reservoirs of PrV for domestic pigs but also other animal species including hunting dogs. This article presents a case report of PrV infection in two hunting dogs from different central Croatian districts. Clinically, symptoms regarding the CNS and automutilation predominated in both animals, following their death. Histological evidence of perivascular infiltration of brain tissue, positive cytopathological changes after inoculation into cell culture and PCR confirmed the presence of PrV. Further sequencing of PrV gC genome fragment confirmed the presence of Clade A genotype, similar to strains derived previously from domestic pigs and wild boars in Croatia. The first description of pseudorabies in hunting dogs in Croatia confirming the possibility of viral transmission through contact from wild boars to hunting dogs has been presented.
