ABSTRACT
The dorsal notch and incomplete ossification of the occipital bone in the 8 month old puppy of Papillion dog was described. Although at occipital dysplasia, the neurological signs did not occur. On the base of the standart craniometrical measurements, the type of the skull was idnetyfied as mesocephalic. The height of dorsal notch was 5.28 mm and the foramen magnum index equals 162.54
and dysplasia index 54 in post mortem examination. The literature is a
source of various opinions about dorsal notch. Some authors qualified this as
anatomical variation, but others suggest the dorsal notch occurs for example
in cases of occipital hypoplasia and syringomyelia.
Key words: occipital dysplasia, skull, dorsal notch, foramen magnum, Papillion.
