Sealyham Terrier Breed History

Between 1850 and 1891, Edwardes worked at his estate of Sealyham in Pembrokeshire to develop a breed that would hunt badgers by sight and scent. Although the exact heritage of this terrier is unknown, dogs that may have helped form it include basset hounds, bull terriers, the fox terrier, the West Highland white terrier, Welsh corgi, the Cheshire terrier and the Dandie Dinmont terrier. Edwardes reportedly allowed tenant farmers to raise the Sealyham pups in order to train them. If at around 11 months of age, the dogs were able to face a fox or badger, the farmers received extra fees. The breed first appeared in the show ring in 1903. The first Sealyham Terrier's club was formed in 1908, and the dog was recognized by the AKC in 1911. The Sealyham does well as both a competitive show dog and a hard-working hunter. It is found mainly in England and South Africa today.

Sealyham Terrier Breed Appearance

This short-legged terrier is rectangular in shape with a strong, flexible body – perfect for passing in and out of tight areas. Its expression is alert and determined. The Sealyham’s weather-resistant coat is soft and compact underneath with a stiff, wire outer coat. It is colored in solid white or with lemon, brown, blue or badger markings on head and ears.

Sealyham Terrier Breed Maintenance

The Sealyham’s wire coat requires combing two to three times per week to prevent matting. Shaping should be done by clipping for pets or stripping for show dogs every three months. These terriers need a moderate amount of exercise such as a daily walk or a game. This breed has a good nose and may follow scents if let off the leash. It should be given obedience training, as it is an independent breed and requires constant attention. It is quick to learn, but will challenge your authority from time to time. If spoiled instead of given consistent training, it may become an overbearing, nippy pet. The Sealyham terrier does well in an apartment or a country home as long as it receives adequate exercise.

Sealyham Terrier Breed Activity Requirements

The Sealyham Terrier is calmer than most terriers, however it is still a very active breed. It likes to explore and chase and has a tendency to bark and dig, especially if left alone in the yard. The Sealyham is a hard-worker, but very independent. It can be strong-willed and stubborn, but loves its family and is very devoted to them. It is aggressive toward other pets and should be socialized at a young age in order to adapt to cats. This breed will do well with older children if given the opportunity to interact as a puppy. It is reserved around strangers.
