AKC Terrier Group
The Sealyham Terrier was originally developed in Wales in the mid-1800s by Captain John Edwardes. Although Edwardes kept no breeding records, sources believe the Sealyham was produced from crosses between the Corgi, Dandie Dinmont, West Highland White, Wirehaired Fox Terrier, Bull Terrier, and perhaps even some hounds. The Sealyham was named after the estate of the breed’s creator. Like many other long, low terriers, the Sealyham was used to hunt den animals such as fox, badger, and otter. Captain Edwardes tested all puppies and allowed only the game, valiant pups to live, shooting the rest. His foundation stock was very tough indeed. Today’s Sealyham temperament is quite a bit mellower. The Sealyham has become mostly a companion dog, though he still makes a good ratter.
The Sealyham is a strong white terrier with a long, broad head, slightly domed skull, powerful jaws, and bushy eyebrows, mustache, and beard. The topline should be level. It is short-legged, slightly longer than tall. The dark eyes are oval. The nose is black. The broad ears are folded level with the top of the head. The chest is deep and lowered well between the legs. The docked tail is carried straight up. The harsh, wiry coat comes in white, with or without lemon, tan, or badger markings on the head and ears.

Good for older owners because the breed isn’t demanding or rowdy. The coat needs regular attention. Likes to dig and bark. The bark is surprisingly loud for a small dog. Prone to deafness. Check parents and litter by making noises and trying to attract their attention. If in doubt, have the puppies BAER tested. Some bloodlines are prone to skin and back problems, and glaucoma. Does not do well in very hot conditions.
