Name the condition: Occipital dysplasia

Comment: Occipital dysplasia, colloquially termed a "keyhole foramen magnum" has been identified in a number of toy or small dog breeds, including the Cavalier King Charles Spaniel, Yorkshire terriers and Pomerianians, among others. In the Cavalier King Charles spaniel it may be associated with malformation of the caudal fossa (Chiara-Like syndrome) and syringomyelia. It is estimated that up to 95% of Cavalier King Charles Spaniels possess the defect, with up to 50% having other parts of this syndrome.

The defect arrises from a failure of incomplete ossification of the ventromedial portion of the supra occipital bone, and is often replaced by a band of connective tissue.
