Canine Parvovirus (CPV) is a highly contagious viral infection caused by a member of the Parvoviridae family and is a major cause of death in puppies under six months of age. In addition to the viral infection, nematode worms were also present, which are suspected to exacerbate the condition and suppress the immune system (immunosuppressive effect). This study aimed to determine the cause of death in a Miniature Pomeranian dog showing clinical signs of acute gastroenteritis. The subject was a 2-month-old male dog presenting with lethargy, loss of appetite, and foul-smelling bloody diarrhea. The methods included anamnesis, clinical observation, epidemiological investigation, gross pathological examination, histopathology, virological testing using PCR, fecal parasitological examination, and bacterial isolation and identification. Epidemiological analysis showed a morbidity rate of 60%, a mortality rate of 40%, and a case fatality rate (CFR) of 66% in the surrounding environment of the case. Gross pathology and histopathological examinations revealed various inflammatory lesions. PCR testing confirmed the presence of Canine Parvovirus infection. Parasitological examination revealed eggs and two adults Toxocara canis worms, as well as two adult Ancylostoma caninum worms, with a mild level of infection. Bacterial identification in the intestines revealed only Escherichia coli as normal flora.
