More details about the Sealyham Terrier

Sealyham Terrier: Origins and history

Captain John Tucker developed the Sealyham Terrier in the 1800s on his estate, Sealyham (hence the breed name) in Haverfordwest, Wales. He was looking for a dog who could hunt for small but hardy wildlife such as foxes and badgers. The breed quickly gained popularity over in England and was especially loved by the rich and famous, including the British royals. Although the breed was popular in the early 1900’s, it’s now an extremely rare breed.

Training a Sealyham Terrier

This breed, like most terries, is known to be a bit troublesome in the training department. Due to his independent nature, the Sealy requires firm and consistent leadership - otherwise, he’ll quickly try to get the upper hand. Positive reinforcement is the best method, so use plenty of healthy treats and praise.
