Pesq. Vet. Bras. 32(Supl.1):1-3, dezembro 2012 1 RESUMO.-[Descrição anátomo-radiográfica do esqueleto axial do cachorro-do-mato (Cerdocyon thous).] O objetivo deste trabalho foi descrever o esqueleto axial de um carnívoro selvagem brasileiro, o cachorro-do-mato (Cerdocyon thous). Cinco animais foram previamente descongelados para exames radiográficos e posteriormente submetidos a dissecação óssea e maceração química. Os animais apresentavam sete vértebras cervicais e, à partir da terceira, eram mais curtas e largas e o processo espinhoso mais evidente a partir da quinta vértebra cervical. Há treze vér-tebras torácicas e o processo espinhoso das vértebras lombares, que são sete, diminui partir da quinta vértebra. O sacro é constituído por duas vértebras fundidas e há 20 ou 21 vértebras caudais. Pode-se concluir que o esqueleto axial do cachorro-do-mato se assemelha ao do cão doméstico. The aim of this study was to describe the axial skeleton of a wild Brazilian carnivorous, the crab-eating fox (Cerdocyon thous). Five specimens of crab-eating fox were previously unfrozen for radiographic exams and their bones went through dissection and chemical maceration. This animal presents seven cervical vertebrae, and from the third on, they become shorter and wider than the other ones e the spinous process was makeable from the fifth cervical vertebrae on. There are thirteen thoracic vertebrae and the spinous process of the lumbar vertebrae, which are seven, decreases from the fifth on. The sacrum is formed by two vertebrae and there are twenty or twenty one caudal vertebrae. It can be concluded that the crab-eating fox axial skeleton is similar to that of the domestic dog.
