Are you a lover of terriers but wish they were a little calmer and more docile? The Sealyham Terrier might just be your perfect match! This quirky dog was originally used to hunt small game, but has since become popular as a loving companion dog. While the Sealy (as he’s often known) still loves a good walk and enjoys exploring, he’s far less active and calmer within the home than most other terriers. Known for his clownish personality and great sense of humour, this breed makes for a wonderful pet and/or working companion - though it’s worth noting that this breed is extremely hard to come by nowadays.

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.

    Description

    While the Sealy is classed as a small dog, he’s definitely on the bigger side of the small breeds. His body is quite long and muscular, sturdy but set fairly low on the ground. His legs are short but robust, and his tail is medium in length. The head of the Sealyham Terrier is long and wide, with dark deep-set eyes, black noses, and big ears that are rounded at the tips.

    Good to know

    Sadly, the Sealy is an extremely rare breed and is scarily close to extinction. To find one, you’ll need to get in touch with a breeder and be prepared to wait.

      Independent

        Tolerates solitude

        If a Sealyham Terrier is accustomed to being left home alone from a young age, he generally copes fine with some alone time. However, if it happens fast and without slow adjustment, the Sealy may suffer from separation anxiety.

        Easy to train / obedience

        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.

        Tendency to run away

        With a strong prey drive and a natural instinct to dig, the Sealyham is likely to run off without notice. Make sure your garden is extremely secure and keep the dog on a lead around wildlife and small animals, at least until your Sealy is extremely well-trained and socialized.
