Clinical signs, haematology (leucopenia, lymphopenia, neutropenia) and results at necropsy may only suggest a disease suspected of a parvovirus etiology. Real proof of this kind infection is based on identification of canine parvovirus in faeces of a sick dog. Because of the common occurence of CPV-2 infections in dogs there is need to introduce a rapid test which would make it possible to perform a proper diagnosis immediately after the collection of the samples of faeces in hospital. In this paper the presence of CPV-2 was demonstrated by means of the test developed by On-Site Biotech (Uppsala, Sweden) on 41 of 50 stool samples with clinical signs suggesting parvovirus disease. Of 41 infected dogs 40 were leucopenic (leucocytes ≤ 4.5 G/L), lymphopenic (lymphocytes ≤ 1.3 G/L) and neutropenic (neutrophiles ≤ 4.0 G/L). Of nine dogs uninfected with CPV-2, none showed leucopenia, lymphopenia or neutropenia.
