The coat colours range from dark gray to jet black and brindle, a mix of black and brown. Scotties with wheaten (straw to nearly white) coats sometimes occur, and are similar in appearance to the Soft-Coated Wheaten Terrier or West Highland White Terrier. Two genetic health concerns seen in the breed are von Willebrand disease (vWD) and craniomandibular osteopathy (CMO); Scottie cramp, patellar luxation and cerebellar abiotrophy are also sometimes seen in this breed. Common eye conditions seen in a variety of breeds such as cataracts and glaucoma can appear in Scotties as they age. There are no specific conditions relating the skin that affect the breed, but they can be affected by common dog related conditions such as parasites and mange. Scotties typically live from 11 to 13 years.
