If infants are placed on the back for a long time in the same position, it could lead to «positional plagiocephaly», a
case of flattened or misshapen head and «
brachycephaly», the flattening of the back of the skull.
For
brachycephaly, three breeds were considered as
cases (Pugs, Boxer and Pekingese) and 13 breeds (Afghan Hound, Akita, Basenji, Basset, Dachshund, Eurasier, German,Short - Haired, Pointer, Greyhound, Leonberger, Pembroke Welsh Corgi, Poodle, Saluki, and TibetanTerrier) were considered as controls.
