Additional information (Wiki): Westies are prone to allergies and dry skin issues, and bathing too frequently may aggravate these problems. Washing once a month or on a longer interval will generally not cause issues. However, frequent brushings are needed to keep the coat clean and oils evenly distributed throughout the coat. Washing with a detergent-free, baby-oriented, or another soft skin shampoo will help keep a Westie's skin hydrated. Weekly washing of the inside of the ears with cotton balls will prevent oil and wax build-up and ear infections. Water in the ears must be removed before an infection develops. Westies should be groomed at least every two months, and bathed and brushed as needed between appointments.

They also have deep chests, muscular limbs, a huge skull, a short and a closely fitted jaw with "scissors" bite (lower canines locked in front of upper canines, upper incisors locked over lower incisors). Their teeth generally appear quite large for the size of the dog. Westies have a very strong bone structure for their size.

They have a soft, dense undercoat and a rough outer coat, about 2 inches long, that requires regular grooming. Some Westies have "wheaten tippings" on their backs, though for individuals put forward for conformation showing this can be regarded as undesirable. Also, some Westies do not have a top corse coat, and just a second silky coat.

This breed is a non-shedding dog. As they develop into adults, their thinner "puppy coat" is normally removed by either 'hand-stripping' or otherwise clipping.
