Shetland Sheepdog

Personality

A Sheltie is a sensitive, affectionate dog that tunes in closely to its household. The AKC describes the breed as playful, energetic and bright, and most Shelties want to spend their day near their own people. With strangers they tend to hold back, sometimes to the point of shyness, so gentle early socialization matters.

Barking is the trait new owners notice first. Shelties use their voices to announce visitors, share excitement and keep the household in order, so plan to teach a "quiet" cue early. The same herding wiring can show up as heel-nipping during play and a strong urge to chase anything that moves.

Most Shelties are good with children and friendly toward other dogs, and VCA calls them a calm but alert housedog. Some are timid, and many are unsettled by raised voices or harsh handling. A warm, predictable home suits them best.

History

The Sheltie comes from the Shetland Islands, north of mainland Scotland, where farmers used small herding dogs to keep sheep, ponies and poultry out of the crops. Islanders nicknamed them "toonie dogs," from a Shetland word for farm. Their compact size suited a place with little food to spare, much like the islands' famously small ponies.

The exact recipe is a puzzle because nobody wrote it down. Collie-type dogs from the mainland were clearly part of the mix, and some historians add older island herding dogs, so the Sheltie is not simply a shrunken Collie. The islands' isolation kept the breed little known elsewhere until the early 1900s.

The Kennel Club in England first recognized the dogs as Shetland Collies in 1909, but Collie fanciers objected and the name soon changed to Shetland Sheepdog. The first Sheltie on the AKC's books was Lord Scott, a dog imported from Shetland in 1911, and the national breed club formed at the 1929 Westminster Kennel Club show.

Appearance, coat & colors

Shelties look like a Rough Collie in miniature. The AKC lists a height of 13 to 16 in (33 to 41 cm) and a weight of 15 to 25 lb (7 to 11 kg) for both sexes. The body is deep-chested and level-backed, the head is a long, blunt wedge, and the small ears tip forward when the dog is on alert.

The coat is the main event. A harsh, straight outer coat sits over a short, very dense undercoat, and the long hair forms a mane around the neck while the face stays smooth. The AKC lists black, blue merle and sable, usually with white markings, and sable comes in several shades, including a rich mahogany.

Tricolor and black-and-tan dogs also occur. Most Shelties have dark brown eyes, but merle dogs may have one or both eyes blue.

Training

Shelties are among the easiest breeds to train. They learn from a few repetitions, love to please, and shine in obedience, agility, herding and tracking. Because they are sensitive to correction, VCA recommends reward-based methods using food, games and praise.

Start a puppy class early and socialize widely, since Shelties can be reserved with strangers. Teach "quiet" as deliberately as you teach "sit": reward calm moments, and interrupt barking before it builds. For doorbell barking, reward your dog for settling on a mat instead of rushing the door.

Herding dogs like to chase moving things, and the AKC notes that Shelties may go after cars, so they need a well-fenced yard and a leash on walks. Teach a dependable recall. If your Sheltie nips at ankles during play, redirect to a toy and end the game calmly. Trick training and sports give that quick mind something to do.

Exercise

Moderate daily exercise is enough for most adult Shelties, and the AKC says they fit easily into their family's routine, city living included. VCA suggests a long walk, a short run or yard games. Shelties also need a job for the mind, such as agility, herding, obedience, tracking or learning new tricks. Our guide to how much exercise a dog needs helps you match activity to age.

Mental work counts as much as miles. Puzzle feeders and short training games earn their keep on rainy days, when a walk gets cut short.

Keep walks on a leash and play in a fenced area, since the urge to chase is strong. Ask your vet when a growing puppy is ready for jogging or agility jumps. In hot weather, exercise early or late and carry water. The thick coat protects against heat as well as cold, but it is not a cooling system.

Grooming

Plan on brushing a Sheltie at least weekly, and every other day is better. VCA says the double coat needs combing that often to prevent mats, and the AKC notes that the breed sheds considerably, especially in shedding season. A slicker brush and an undercoat rake or deshedding tool do most of the work.

Check the places where mats form first: behind the ears, under each front leg at the elbow and in the "pants" beneath the tail. Brush the coat to the skin before a bath so tangles do not tighten when wet. Bathing is only needed occasionally.

Do not shave the coat. The AKC points out that the coat shields the skin from sun and heat as well as from cold. Trim nails regularly, check the ears and brush the teeth several times a week. Expect hair on clothes, furniture and floors all year; a good vacuum is part of Sheltie ownership.

Feeding

Shelties do well on a complete and balanced diet suited to their life stage. The AKC says a high-quality commercial food, or home-prepared food made under your vet's supervision, can both work. VCA notes that the breed tends to stay at a good weight, though some dogs do gain, so keep an eye on the scale.

Measure meals, count training treats toward the daily total and check your dog's shape often. All that fluff hides weight gain, so feel for the ribs under the coat instead of judging by sight. The dog food calculator gives a starting estimate, and your vet can fine-tune it for your dog.

Most adults eat well on two meals a day. Keep fresh water available at all times, and ask your vet before adding supplements or changing diets. If you want to cook for your dog, a veterinary nutritionist can design a balanced recipe.

Health

Shelties are generally healthy, and the breed's parent club says its known health problems are not common, but several inherited conditions deserve attention. The AKC and the American Shetland Sheepdog Association list hip dysplasia, thyroid disease, eye disease, dermatomyositis (often called Sheltie skin syndrome), von Willebrand's disease (a clotting disorder), gallbladder mucoceles and epilepsy.

One Sheltie-specific issue is the MDR1 mutation. Washington State University's veterinary pharmacology program reports it in Shelties, Australian Shepherds, Collies and other herding breeds, and dogs with it can react severely to certain common drugs. A DNA test shows whether your dog carries it, so ask your vet about testing before any new medication.

Schedule yearly checkups, and tell your vet about limping, skin sores, seizures or changes in appetite or thirst. Good breeders follow the parent club's minimum testing recommendations through the Canine Health Information Center (CHIC) program and will share the results.

Health conditions to know about

• Hip dysplasia — Inherited hip malformation; the AKC lists a hip evaluation among the parent club's recommended tests.
• Eye disease — The AKC and the parent club list inherited eye diseases; breeding dogs should be examined by a veterinary ophthalmologist.
• Dermatomyositis — An inflammatory skin condition, also called Sheltie skin syndrome, listed by the parent club.
• MDR1 drug sensitivity — A gene mutation that can cause severe reactions to certain medications; a DNA test is available.
• Thyroid disease — Listed by the AKC and the parent club; your vet can screen with bloodwork.
• Gallbladder mucocele — A gallbladder problem the parent club lists as a known concern; tell your vet about vomiting or belly pain.

Health tests to ask a breeder about

• Hip evaluation
• Eye exam by a veterinary ophthalmologist
• MDR1 DNA test
• Thyroid evaluation

Living with a Shetland Sheepdog

Shelties adapt to many homes, including apartments and city life, if exercise and noise are managed. Barking is the real apartment challenge, since neighbors may hear every hallway sound, so early training and enough mental activity matter. A quiet cue built in puppyhood helps a lot.

These are devoted family dogs that attach closely to their people, and VCA describes them as one-family dogs that can be aloof with outsiders. Plan for company during the day, and introduce visitors gently.

Shelties live comfortably with children and other dogs, though a Sheltie may try to herd small children by nipping at heels, which is a training matter rather than aggression. The double coat handles cool weather well. In humid summers, keep exercise gentle, offer shade and water, and keep the house cool.

Puppies, breeders & rescue

Look for a breeder who tests both parents and shares the results. The parent club recommends minimum health testing through the CHIC program, which for Shelties includes a hip evaluation and an eye exam by a veterinary ophthalmologist. Ask about MDR1 status too, since a simple DNA test shows it. Ask to see the paperwork, ideally in the OFA database, and ask about any thyroid problems, skin disease or seizures in the family.

Meet the mother, see where the puppies are raised and ask how they are introduced to people, sounds and handling. A good breeder offers a written contract and will take the dog back at any age. Prices vary widely by region and bloodline, and a high price does not prove good health.

Adult Shelties also turn up in breed rescues and shelters, sometimes because owners were not ready for the barking or the grooming. Our breed selector can help you compare the Sheltie with other breeds before you decide.
