History - Sealyham Terrier for Sale

sealyham terrier - historyThe Sealyham Terrier is a rare dog breed originating in Wales. The dog was developed in the 19th century by Captain John Edwardes at Sealyham House. The Sealy has been associated with members of the British Royal Family, but its numbers declined to such an extent that it was listed as a vulnerable native breed by the Kennel Club.

The Sealyham Terrier club was created in 1908 and the dog breed was officially recognised by the Kennel Club in 1911. This dog is now recognized by all the major kennel clubs. The American Sealyham Terrier Club was founded in 1913.

Description - Sealyham Terrier for Sale

sealyham terrier puppy - descriptionThe Sealyham is a dog that stands low to the ground and its height shouldn’t exceed 27 - 30cm and weight should be about 8 - 9kg.

The double coat is considered non-shedding and is wiry and weather resistant. It is nearly always white but can be fawn. They’ve got big heads with dark, deep set eyes. The ears are semi-erect, semi-floppy and the tail is usually docked.


Affectionately referred to as Sealy, there aren't too many of these little dogs left. At one time, they were a very popular terrier breed, but today they are uncommon – almost endangered.

He’s a social dog with his human family but tends to be reserved around strangers. He also tends to be just a little bit more mellow than some of the more rowdier terrier breeds.

He gets on well with other dogs in the home as well as with children. He is an intelligent little dog but is inclined to be stubborn so you have to show him both firmness and kindness and also think about obedience training for him.

He’s amicable and adjusts well to life in the city or the countryside.

Health Problems - Sealyham Terrier for Sale

sealyham terrier puppies - health problemsThis is a hardy dog breed and you don’t hear of many health problems associated with him. It seems as though you might have to watch out for an eye condition known as lens luxation. It's an eye condition with dogs where the lens slips out of position because of weakening of the fibers that hold it in place.

There is a lack of fluid in the eye causing optic nerve damage and this can lead to blindness.

Retinal Dysplasia is another eye problem . This is a developmental malformation of the retina that the dog is born with. Symptoms in dogs are a reluctance to jump off things such as the bed or he may even bump into things.

Atopic Dermatitis is something the Sealyham is more prone to. Its an allergic skin disease which drives a dog mad with its itchiness. Your pet will certainly need treatment from the vet to relieve it.

Caring The Pet - Sealyham Terrier for Sale

sealyham terrier dogs - caringProvide your Sealy with his own warm, dry bed.

Brush the long, weather-resistant coat at least twice a week. Hand-stripping of the coat will maintain the wiry, hard texture, but because this method can be quite a laborious process, many Sealy owners rather have their dog professionally clipped.

Check inside his mouth for bad teeth as well as inside the ears for signs of infection. His eyes should also be clear and free of discharge.

His nails will also need to be trimmed.

The Sealyham doesn’t require a lot of exercise but he must at least be given a walk every day.

Ensure the vaccines are up to date. They start when your pet is just a puppy. Remember to get your dog to the vet when you suspect that he is ill.

Feed your Sealyham with good food. Make sure you’re feeding your pet a high quality food as this promotes health and longevity. Provide your Santal Hound with top quality food to ensure his health.

Always choose the quality commercially manufactured foods on the market – those that have natural, good ingredients in them. Try to include some home-made food for him which can be simply mixed into the dry kibble twice a week.

There is no need to offer your dog a host of different foods. Dogs want simplicity and consistency. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots is super tasty and nutritious. If you can, also try and include a little bit of raw meat to his diet occasionally as this can go towards ensuring he doesn’t get skin diseases.

Make sure that a constant supply of fresh, cool water is available to your dog.
