Appearance
The Sealyham Terrier is a small but strong terrier with a large head, domed skull, and a distinctive bushy beard. The oval shaped eyes are wide set and dark in color, always keen and alert. The pendant ears are folded level with the top of the head, have rounded tips and should reach the outer corner of the eye. The topline is level and the back should be as long as the dog is tall. The tail is set forward on the body, carried upright and is customarily docked. The harsh, crisp coat is typically white, but some darker markings are permissible on the ears and head.
Size and Weight
The ideal size for a Sealyham Terrier, regardless of gender, is 10.5 inches at the shoulder. Males typically weigh 23 to 24 pounds, while females weigh slightly less. Height is of more importance in the show ring than weight.
Coat and Color
Sealyham Terriers sport weather-resistant double coats of medium length. The top coat is wiry and crisp, the undercoat is soft and thick. The muzzle is covered in a long, thick beard. They are usually entirely white, but some have lemon, tan or badger markings on the ears and head.
Grooming Needs
The Sealyham coat should be brushed three times per week to prevent tangles and mats from forming. The proper texture is maintained through hand-stripping the coat several times a year, a must for show dogs, but an optional treatment for house dogs. Clipping is often chosen as an alternative to stripping for dogs who will not be shown. Clipped Sealyham's however, have a soft coat and shed more frequently. Bathe as needed, depending upon the individual dog's activity levels.
Check the ears on a weekly basis for signs of infection, irritation, or wax build up. Cleanse regularly with a veterinarian-approved cleanser and cotton ball. Brush the teeth at least once per week to prevent tartar buildup and gum disease. Small dogs are prone to dental problems as they age, so brushing more frequently is encouraged. Additionally, nails should be trimmed once per month if the dog does not wear the toenails down naturally.
