Sealyham Terrier Temperment

A determined, alert, and willful small dog, the Sealyham Terrier is an independent and undemanding dog. These dogs can be very strong headed and stubborn making training something of a challenge - he is best suited to a confident and assertive owner with some experience of dog ownership. The Sealyham Terrier needs to be socialized early on to promote a stable temperament, and firm, consistent training is important. These dogs enjoy digging, have a loud bark, and can be possessive of his belongings and food, so don't expect a quiet life when you have a Sealyham Terrier around. They also do not enjoy being handled roughly or teased, which is why they are better around older children that will not pester them.

Although the Sealyham Terrier can be very entertaining when he wants to be, he can also be calm and steady. These dogs are loyal and devoted when it comes to their families, but are not clingy pets. They are not overly active, but do enjoy regular walks as well as somewhere safe and secure to play - this is important, as the Sealyham Terrier tends to wander off chasing anything that makes the mistake of running away from him. These are adaptable dogs that will be happy living in an apartment as well as a house. His loud bark and devotion ot his family makes the Sealyham Terrier an effective watchdog. He can be stand offish and wary around strangers, and early socialization is advisable with other animals. They can also easily enter into quarrels with other dogs. Although the Sealyham Terrier can be bossy, he is intelligent and a quick learner, so with the right owner training can be less challenging.

Sealyham Terrier Grooming

The grooming requirements for the Sealyham Terrier can be quite extensive, and you will need to brush his coat two or three times a week. For hygiene reasons his beard should be combed and cleaned on a daily basis. Every few months his coat may need to be clipped, or in the case of show dogs will need to be hand stripped. However, with proper grooming these dogs are low shedders, and may therefore suit those with allergies.

Sealyham Terrier History

This breed has an interesting history. The Sealyham terrier derives its name from Sealy Ham, Haverfordwest, Wales. Captain John Edwards developed this breed around 1848 as a hunting dog for vermin and fox.

Captain Edwards did not keep any records of his endeavors but later students surmised that the original terriers were probably descendents of white-haired terriers which Edwards' Flemish ancestors brought to Wales at the time of the Norman Conquest. It is also assumed he used a small white terrier resembling a bull terrier which is now extinct to begin the breeding.

The Sealyham's first recorded show appearance was in 1903 at a local affair in Wales and the breed was first imported to the U.S. in 1911.

Sealyham Terrier Training

This breed can be a challenge. The Sealyham terrier has a tendency to be difficult to train. They are quick to learn, but they have also been known to try to undermine their master's authority. For the most part, they do well with early socialization and obedience training.

Sealyham terriers respond best to firm, fair, and consistent direction. They enjoy agility exercises and are enthusiastic participants in activities but they will run off if they decide to chase something.

Owners can use food and praise methods as forms of training but do not be surprised if these methods do not work all the time.

Physical punishment will not work with terriers and will only make them more difficult to train. Teasing will produce the same results. Demonstrating consistent leadership so that a Sealy respects your decisions is more important than advanced obedience exercises.

Because of their inbred temperament, it is often best to have the breed trained early on in life and this training may need to be performed by a professional who is knowledgeable about this particular breed. It should never be expected that the animal will be completely docile or lose its hunter instincts, but you can teach it to behave within certain boundaries if that training is conducted early on and performed correctly.

Sealyham Terrier Health Problems

The life expectancy of the Sealyham Terrier is around 12-15 years. There are a number of health problems to look out for with this breed, and this includes spinal problems, PRA, deafness, heart problems, cataracts, and glaucoma. Puppies should come with BAER certificates, and the parents of the Sealyham Terrier puppy should have CERF certificates.

My name is "Buddy" and I'm a yellow lab. My favorite thing to do is fetch a ball. I also like to bark at cars and go swimming in the lake whenever I can. It's great to be a dog!
