Standing less than 11 at the shoulder and weighing about 24 pounds, the celies are not large enough to be considered medium-sized dogs, but they are the strongest and most important of what we think of as small dogs. Huh.

A typical cili is well muscular, built from the ground down, and moves smoothly with long, fixed steps. The weatherproof coat is predominantly white, and has a long, wide head fitted with gorgeous facial hair. Despite her representative as a bruiser among short-legged terriers, Seeley is cute, funny, affectionate, outgoing and trained, if a bit stubborn. His vigilance and the bark of a large dog make Sealys an excellent watchdog. Blessed with an adaptable nature, the Sealys are responsible for city housing or country life.

The name Sallyham Terrier honors the Selly Ham estate on the Seal River in southwestern Wales, where this strong and confident terrier was born first. The breed’s father was an army captain named John Edwards, who retired at the age of 40 in the mid-1800s and spent the rest of his life developing his dream dog.

Seeley’s primary objective was to work in support of the Captain’s Otterhound Pack. Beaver was considered a pest in those days, which reduced fish populations on vast estates such as silly ham. Edwards made his terrier so strong and tough that he could drive the razor-toed beaver out of his den. Edwards left no written record of his breeds, and modern officials disagree with the exact lineage of the Captain’s original Sealys. The names of the breed tied to his theories are Bull, Dandy Dinmont and West Highland White Terrier. Whatever the exact breed mix, the captain was admirably successful, creating a fearless, hardworking hunter who was also a delightful companion on the edge of the fire. The years between the World Wars were the American heyday of the breed. The Sealys won Westminster’s Best in Show award three times in this era, among them the most famous show of the Prohibition era was Dog, a Seeley named Bootlegger. His high profile was further promoted by A-list Hollywood owners such as Humphrey Bogart, Gary Cooper and Carrie Grant.

Seeing many of the breed’s best traits, Seeley’s popularity with pet owners has diminished since those primeval days – surprising. “”They can be one of the best kept secrets in dogs,”” says a Seeley lover. Today’s breed is slightly larger and more sociable than the feudalistic terrier first bred by Captain Edwards. Their friendships are well used as medical staff in nursing homes and children’s hospitals.

General Appearance

The Sealyham Terrier has a weather-resistant, medium-long double coat. The undercoat is dense and soft, while the top coat is hard and hard. The hair around the face and muzzle is very long compared to the rest of the coat. Seals are all white, although some have lemon, tan or badger markings on the head and ears.

The gestation period in lasts for 60-64 days The primary period of the reproductive cycle of the female is called Proestrus and goes on for around 9 days. During this time the females begin to draw in males. The subsequent part is the Estrus when the bitch is receptive to the male. It goes on for around 3 to 11 days. The third part is the Diestrus. Usually, it happens around day 14. In this period the bitch’s discharge changes for distinctive red and reaching its end. The vulva gets back to average, and she will no longer allow mating. The fourth part called the Anestrus. The time span between heat periods ordinarily keeps going around a half year. The litter size ranges between 6 to 8 puppies at a time’


The breed’s weather-resistant, double “jackets” and prolific legs and body accessories must be combed and brushed every two or three days, as the seal coats easily mat. The coat does not fall but must be regularly stripped by hand or clipped. Abdomen celhiams can be kept small with minimal decor, which makes them easy to care for. Taking a bath every three to four weeks is a good idea. For celhiams in show coats, it is necessary to wash at least the equipment repeatedly. Nails should be cut regularly, and the eyes and ears should be examined during the grooming session.


Like most terriers, the Sealys require a firm, but not rigorous training technique. The Seeley puppy should be socialized quickly, slowly exposed to a wide range of dogs, people and places, and this will help discourage dog aggression later. Sealys can be food preservatives, and should be corrected immediately. Never let the dog get away from it.


The Sealys like to run safely in the enclosed area and enjoy plenty of exercise. They can overheat in hot, humid climates, so it is best to exercise in the morning and evening. Grass stains are common, and it may be necessary to wash the baggage and condition frequently. Encourage the Sealys to exercise so that they are moderately tired, but not fatigued, and they will remain calm in the house. Sealys can be very active, and exercise helps them become better domestic pets.


Sellyham Terriers should perform well on high quality dog ​​food, whether it is commercially manufactured or prepared at home with the supervision and approval of your vet. Any diet should be appropriate for the age of the dog (puppy, adult, or senior). For Seeley attending dog shows, avoid food with excess dye, as the dye stains the beard and can also color urine, which can cause hair to turn yellow. Some dogs are at risk of being overweight, so watch your dog’s calorie consumption and weight levels. Treatment training can be an important aid, but giving too much can lead to obesity. Know which human foods are safe for dogs and which are not. Contact your vet if you have any concerns about your dog’s weight or diet. Clean, fresh water must be available at all times.


Allergies are quite common in the breed but are rarely serious in nature. There are many genetic eye diseases that potential sires and dams should be tested before breeding. The American Sellyham Terrier Club provides detailed information about the health of the breed. The breed’s long eyebrows can lead to non-genetic eye conditions such as tearing and infection. If the dog is domesticated, a small eyebrow fall is a good idea. Ear infections can occur due to the weight and position of the ears, but usually keeping the ears clean is essential for prevention and maintenance.

Recommended health tests from the National Breed Club:

  • Ophthalmologist evaluation
  • PLL DNA test
