The exposure of 13 Brazilian free-ranging nondomestic canids (five pampas fox - Pseudalopex gymnocercus and eight crab-eating fox -Cerdocyon thous) from Southern region of Brazil, to Canine distemper virus (CDV), canine parvovirus (CPV) and Canine coronavirus (CCoV) was investigated. Antibodies against CDV were detected in 38.5% (5/13) of the samples. There were anti-CDV antibodies in 60% (3/5) of P. gymnocercus and in 25% (2/8) of C. thous. The frequency was higher among the adults and males. Eleven canids (84.6%) presented antibodies against CPV, 80% (4/5) were from P. gymnocercus and 87.5% (7/8) were from C. thous. There was no difference in positivity rate against CPV between gender and age. Antibodies against CCoV were detected in 38.5% (5/13) of the samples, with 60% (3/5) of positivity in P. gymnocercus and 25% (2/8) in C. thous. The frequency of antibodies against CCoV was higher among the adults and males. The study showed that these canids were exposed to CDV, CPV and CCoV.Foi investigada a ocorrência de exposição em 13 canídeos não domésticos de vida livre (cinco graxains-do-campo - Pseudalopex gymnocercus e oito graxains-do-mato - Cerdocyon thous) da região sul do Brasil ao vírus da cinomose canina (CDV), parvovírus canino (CPV) e coronavírus canino (CCoV). Anticorpos contra o CDV foram detectados em 38,5% (5/13) das amostras. Haviam anticorpos anti-CDV em 60% (3/5) dos P. gymnocercus e em 25% (2/8) dos C. thous. A freqüência foi maior entre machos e adultos. Para CPV, 11 canídeos (84,6%) apresentaram anticorpos, 80% (4/5) eram da espécie P. gymnocercus e 87,5% (7/8) eram C. thous. Não houve diferença de positividade para o CPV entre sexos e idades. Anticorpos contra o CCoV foram detectados em 38,5% (5/13) das amostras, sendo 60% (3/5) de positividade entre os P. gymnocercus e 25% (2/8) entre os C. thous. A freqüência de anticorpos para CCoV foi maior entre os machos e adultos. O estudo revelou que estes canídeos foram expostos ao CDV, CPV e CCoV.
