• Abstract:

   

  Any change in the course of embryonic development may result in

  congenital anomalies that may range from small asymmetries to defects with greater

  aesthetic and functional impairments. In this way congenital malformation can be

  defined as any functional or structural anomaly, present at the moment of birth or that

  manifests itself in later stages of life. The causes are linked to events that precede birth,

  and can be inherited or acquired. The objective of this work is to describe the congenital

  malformations identified in 11 dogs, 9 stillborn and 2 neonates, submitted to euthanasia.

  Among the specimens, it was possible to identify animals from the tabletexphalic and

  brachycephalic races. In the animals evaluated, it was possible to identify the following

  malformations: Cleft lip, cleft palate, encephalocele, anencephaly, hydrocephalus,

  macrocephaly, macroglossia, hypotrichosis, genital atresia, omphalocele, congenital

  glaucoma, bladder exstrophy, bone involvement (incisor), phimosis and anal atresia.

  Congenital malformations may be compatible and incompatible with life, may have

  known or unknown causes. The most frequent malformation was the cleft palate,

  reaching 55% of the animals. Then the presence of cleft lip and genital atresia were

  observed, both of which were present in 27% of the cases evaluated. It is important

  to emphasize that neonates and stillbirths discarded due to malformations can be a

  valuable study material, considering that in veterinary medicine this subject is still little

  explored, because when death does not occur immediately after birth, it is difficult to

  evaluate the animals veterinarian in the neonatal period (first and second weeks of life
