Another interesting piece of research from the human world: evidence that skull growth halts prematurely in people with Chiari:

Another interesting piece of research from the human world: evidence that skull growth halts prematurely in people with Chiari: ...

In Comparison of cerebral cranium volumes between cavalier King Charles spaniels with Chiari-like malformation, small breed dogs and Labradors. H. R. Cross, R. Cappello, and C. Rusbridge. J Small Anim. Pract. 2009 Aug; pp.399-405, the researchers suggest: "When compared with Labradors, CKCS had proportionately the same volume of parenchyma in their caudal fossa, hence there is a mismatch of volumes with too much parenchyma in a too small caudal fossa causing overcrowding. This supports either theory of pathogenesis of CM as mesoderm insufficiency during embryology − causing insufficient scope for the mesoderm and ectoderm layers to develop (Marin-Padilla and Marin-Padilla 1981, Nishikawa and others 1997) − or alternatively premature growth plate closure."

"Premature growth plate closure" sounds a lot like the brain keeps growing after the skull stops.

Hi Rod, as an 'average' pet owner, this is exactly my understanding.
