The breed


Sealyham, is the name of a mansion in Wales formerly owned by Captain John Edwardes. Wanting a hunting terrier to work the grounds of his estate Captain Edwardes developed the Sealyham Terrier. He wanted a small terrier that could go under ground and it had to be white so they wouldn’t be mistaken for a badger. The Captain’s breeding efforts from 1850 until his death in 1891, has given the world one of the most desirable members of the terrier tribe.

What type of terrier is it?
The Sealyham Terrier is a friendly charming lovable delightful clown with a terrific sense of humor. He is a dog that likes to play even at an old age. If you see the doormat “walking” across the floor, you can be certain it’s a Sealyham underneath it. He is a devoted companion and a wonderful family member.

General appearance
Should be that of a freely moving and active dog, presenting a balanced picture of great substance in a small compass. Ideal weight about 8.2 – 9kg. Height, should not exceed 31 cm at the shoulder. The Sealyham must be all white. Lemon tan or badger markings on head and ears are acceptable and very popular. The Sealyham requires regular grooming and combing to remove the loose hair, to prevent the coat from matting. The Sealyham should be stripped on a regular basis.

The breed is relatively healthy and sound. SSS recommends to DNA test all dogs for PLL (Primary Lens Luxation) before they are used in breeding. You can order PLL test kit here.
