Title: West Highland White Terrier
Passage: The West Highland White Terrier, commonly known as the Westie is a breed of dog from Scotland with a distinctive white harsh coat with a somewhat soft white undercoat.  The modern breed is descended from a number of breeding programs of white terriers in Scotland before the 20th century.  Edward Donald Malcolm, 16th Laird of Poltalloch, is credited with the creation of the modern breed from his Poltalloch Terrier, but did not want to be known as such.
Title: Craniomandibular osteopathy
Passage: Craniomandibular osteopathy, also known as lion's jaw, is a developmental disease in dogs causing extensive bony changes in the mandible and skull.  In this disease, a cyclical resorption of normal bone and replacement by immature bone occurs along the inner and outer surfaces of the affected bones.  It usually occurs between the ages of 3 and 8 months.  Breeds most commonly affected include the West Highland White Terrier, Scottish Terrier, Cairn Terrier, and Boston Terrier.  It is rare in large-breed dogs, but it has been reported.  Symptoms include firm swelling of the jaw, drooling, pain, and difficulty eating.
