Sealyham Terrier


The Sealyham Terrier (the name derived from Sealyham, an estate of John Tucker Edwards from Haverfordwest, in Wales (UK), is a purebred, developed by Captain Edwards in mid-1800s. It was used to hunt small games, such as otters, badgers, and foxes. Soon after the first Sealyham Terrier came into the scene, their name spread all over the world and was in high demand as a show dog.

They are small dogs, with strong Terrier genes and a large head. They are known for their distinctive bushy beard, two broadly set oval-shaped dark eyes, and a pair of pendant like ears. Their top half is leveled, and the bottom half is as long as its tail. The harsh and white coat is well complimented with dark markings all over its body.

Temperament & Personality

‘Once you go, Sealy, you will never own a different breed”, this statement entirely compliments the Sealyham Terriers. These little dogs with a giant personality make excellent clowns. They are considered to be less active than their other Terrier relatives and are also less yappy and confrontational.

Sealyham Terrier does bark a lot but does not get provoked easily by other dogs and animals. They are great companion breeds and will give emotional support when the owner gets upsets. Considered equally perfect for both the elderlies and small children, the Sealyham Terriers will make a great partner in all sorts of crimes (pun intended).



The Sealyham Terriers are prone to get overweight easily, thus they need regular activities. They require a steady short walk at the dog park, although an hour of a play session in a dog crèche will also satiate their activity needs. Limited or no daily activities can generate behavioral issues.


The coat of the Sealyham Terriers is Weather resistant, with a  double layer. To look their most glamorous self, these Sealies need a brushing of their fur three times a week. Proper brushing will also prevent tangling and matting of the coat, especially in areas such as head,  leg, and chest. Hand- stripping is a great option to pluck off dead hair from the dog’s coat. Other maintenance needs include regular dental hygiene and the nail care.

Health Problems

Sealyham Terriers can suffer from health issues like Lens Luxation, Retinal Dysplasia, etc. To avoid such health issues, the owner should always buy a new Sealyham Terrier puppy from a reputable breeder, who has a health clearance certificate from some celebrated American health organization for the canines.


These dogs are hard to train, especially when it comes to house training techniques. Crate training is crucial for this breed and commands training like, “No”, “Sit”, Come here”  will not only help the owner to control the dog but will also keep it quiet and free from its unnecessary barking. Positive training methods like food rewards and frequent praises will allow the dog to learn things faster.


Diet schedule should be the same as the small terriers and high-quality dry kibbles are just perfect. The quantity to be offered should be within 3/4 to 1.5 cups on a daily basis.
