The Sealyham Terrier dog breed is quite a recent breed, dating back to the middle of the 19th century when Captain John Owen Tucker-Edwardes, from Sealyham Mansion in Pembrokeshire, south-west Wales, decided to create the perfect terrier once he retired in 1848 and could devote more time to hunting pursuits. He used the Corgi, West Highland White Terrier, Wire Fox Terrier, Bull Terrier, Dandie Dinmont Terrier, and Cheshire Terrier, it is believed. The Sealyham Terrier was used, along with Otterhounds, to hunt otter, fox and badger.
The Sealyham Terrier has many typical terrier traits: he is game and fearless, but friendly towards people. Ever alert, he will bark if anything unusual attracts his attention, and he will show his displeasure if another dog picks a quarrel with him. Early socialisation to cats and other dogs is essential. Full of character, he makes a fun, playful companion.
The Sealyham Terrier is generally a healthy and robust breed. Like many breeds they can suffer some inherited eye conditions and so eye testing recommended.
The Sealyham Terrier needs at least an hour's daily exercise, though is capable of more if you can offer it. Being low to the ground, he is a particular mud magnet in wet weather, so accustom him to being dried from when young, so he views it as an enjoyable, rewarding experience.
Small dogs have a fast metabolism, meaning they burn energy at a high rate, although their small stomachs mean that they must eat little and often. Small-breed foods are specifically designed with appropriate levels of key nutrients and smaller kibble sizes to suit smaller mouths. This also encourages chewing and improves digestion.
Daily grooming will keep the non-shedding coat tangle-free. Mats will otherwise develop, with the long, hard top coat and thick undercoat tangling together. The coat is trimmed expertly for the show ring – a labour-intensive, skilled process that will take some practice to get right! Your breeder will help to advise you. Many pets are clipped uniformly all over.
