The Sealyham Terrier is a small, sturdy breed of dog that originated in Wales. It is known for its distinctive white coat and long ears. The Sealyham Terrier has a strong, muscular body and an alert expression. Its head is broad with a short muzzle and dark eyes. The ears are long and hang down close to the cheeks. The tail is docked to about two-thirds of its original length.

The Sealyham Terrier has an average lifespan of 12 to 15 years, with some living up to 18 years old. They typically weigh between 20 and 24 pounds (9-11 kg) and stand 10-12 inches (25-30 cm) tall at the shoulder. They come in a variety of colors including white, cream, tan, black & tan, blue & tan, red & tan, or brindle & white.

The Sealyham Terrier has an outgoing personality that makes them great companions for active families or individuals who enjoy outdoor activities such as hiking or running. They are intelligent dogs that can be trained easily with patience and consistency from their owners. They are loyal companions who will bond closely with their family members but can also be independent thinkers when it comes to problem solving tasks or learning new tricks!

Sealyham Terriers are friendly towards other dogs as well as people they know but may be wary of strangers at first until they get used to them being around regularly. They tend to get along well with children if socialized properly from a young age but should always be supervised when playing together due to their size difference which could lead to accidental injury if not monitored carefully by adults present in the home environment at all times!

The temperament of the Sealyham Terrier is generally described as lively yet gentle; they make excellent watchdogs due to their alertness but do not bark excessively unless provoked by something out of the ordinary happening in their environment which could potentially pose danger!

In terms of health issues common among this breed include hip dysplasia (a genetic condition affecting joint mobility), eye problems such as cataracts or glaucoma (which can cause blindness), skin allergies/irritations caused by fleas/ticks/other parasites etc., ear infections due to excessive wax buildup inside ear canals etc., so regular checkups with your vet should help keep these issues under control if caught early enough before any permanent damage occurs!

Sealyham Terriers have moderate adaptability levels; they do best in homes where there’s plenty of activity going on throughout the day since they need mental stimulation just like any other breed does - otherwise boredom may set in leading them into destructive behaviors such as chewing furniture/clothing items etc., so it’s important for owners provide plenty opportunities for exercise both indoors/outdoors depending on weather conditions outside too!

Overall these dogs make great pets for those looking for an active companion who loves spending time outdoors - plus they’re relatively low maintenance compared other breeds so you won’t have too much trouble taking care them either way!


The Sealyham Terrier is a small to medium-sized terrier that originated in Wales. The breed was developed in the 19th century by Captain John Edwardes, who bred them for hunting vermin and badgers. They were also used as guard dogs on his estate. The Sealyham Terrier was recognized as a distinct breed in 1910 and was first registered with the Kennel Club in 1911. The breed almost became extinct in the 1970s, but has since made a comeback and is now one of the most popular terriers in the UK.

The Sealyham Terrier is believed to be descended from the White English Terrier, which was brought to Wales by English immigrants in the 18th century. These terriers were then crossbred with local Welsh breeds such as the Corgi and the Welsh Terrier. The resulting dogs were used for hunting vermin and badgers, as well as for guarding homes and farms. In the 19th century, Captain John Edwardes of Sealyham House began breeding these dogs specifically for hunting purposes. He selected for certain physical traits such as a white coat and a strong jaw, which made them ideal for killing vermin and badgers. He also bred them to be good tempered and even-tempered, which made them good guard dogs.

The Sealyham Terrier was recognized as a distinct breed in 1910 and was first registered with the Kennel Club in 1911. The breed almost became extinct in the 1970s due to a lack of interest from breeders, but has since made a comeback thanks to a few dedicated breeders who kept the line going. Today, the Sealyham Terrier is one of the most popular terriers in the UK thanks to their friendly nature and their ability to get along with other pets and children.
