Coat and Colour : Abundant, single coated, soft, silky textured, having a gentle wave that is apparent when standing. When the dog moves, the coat has a free and flowing character to it. Neither woolly nor wiry, crispy nor cottony, fuzzy nor straight. Colour is any shade of wheaten. Upon close examination occasional red, white or black guard hairs may be found. However, the overall colouring must clearly be wheaten with no evidence of any other colour except on ears and muzzle where blue-grey shading may be present. Puppies under one year may carry deeper colouring and some black tipping. The adolescent under two years may be quite light in colour, but must never be white nor carry grey, other than on ears and muzzle. In both puppies and adolescents, the mature wavy coat is generally not seen. Coat colour and texture do not stabilize until about three years of age and some latitude should be given in young dogs. However, the softer and darker puppy coat should not be preferred over the lighter and slightly harsher adult coat. For show purposes, the coat should be trimmed to present a neat terrier outline.

Overstyling is to be discouraged and severely penalized.
