Sealyham Terriers owe their existence largely to the efforts of
Captain John Edwardes who created this breed to help hunt badger, fox,
and otter. Sealyham, in fact, was the name of Edwardes’ British estate.
It is thought that Sealyhams were developed from crosses between
Corgis, Dandie Dinmont Terriers, West Highland
White Terriers, Wire Fox Terriers, and Bull
Terriers. Sealyham Terriers stand approximately 10.5 inches
at the shoulder. Males weigh 23 to 24 pounds, and females just a bit less.
Their coats come in pure white or white with badger, lemon, or tan ear and
head markings. Sealyham Terriers are curious, vivacious, and proud dogs.
Sealyhams generally get along well with people and dogs around their size.
Due to their hunting instincts, they often cannot be trusted around other
