Sealyham Terriers have a white double coat which requires regular brushing with a wire comb in order to prevent matting. It has a dense undercoat, while the outer coat is wiry and weather resistant.

Markings on the face can be in a variety of colours including lemon, black, brown, blue, and badger, which is a mix of brown and black. Heavy body markings or patches or excessive ticking on the coat are discouraged Sealyhams are low to the ground, and in muddy weather their long coats can become quite dirty. Sealyham coats are groomed by hand stripping, in order to keep the coat from becoming too soft.


The breed was developed between 1850 and 1891 by Captain John Edwardes, at Sealyham House, near Wolfscastle in the Welsh county of Pembrokeshire. Originally the breed was used for pest control, to hunt small game, and to eliminate vermin, particularly badgers, which he usually relocated. The Welsh Corgi, Fox Terrier (Wire), and the now extinct English White Terrier all played a part in the makeup of the Sealyham although Edwardes did not keep records. He wanted a small white dog with a strong jaw, and a wiry coat. The white coat was particularly prized, as it meant that the hunter in the field could distinguish the dogs from the quarry.


Although happy in the company of others, they are fine if left alone. Sealyham Terriers are suited for both the town and country. They can be stubborn, vocal, and boisterous but also full of personality.

While they make for loyal family companions, they can be trained to be working dogs, making them excellent mousers or ratters. They can also be taught as a puppy to get along with other animals, including cats and birds.


The breed's weather-resistant, double 'jacket' and profuse leg and body furnishings must be combed and brushed every two or three days, as Sealy coats tend to mat easily. The coat does not shed but must be hand-stripped or clipped on a regular basis. Pet Sealyhams can be kept trimmed short with minimal furnishings, which makes their care easier. Bathing every three to four weeks is a good idea. For Sealyhams in show coat, washing at least the furnishings frequently is a must.
