The Shetland Sheepdog may look like a miniature Collie, but they are far more wary of anything new or unusual. Shelties, as they are known by their admirers, are loyal, loving, and moderately playful and affectionate with their family, especially children when the dog is socialized with the children as a puppy. But with strangers, they are reserved or even reticent. This, when combined with their tendency to bark frequently makes them exceptional watchdogs. But with their reluctance to engage strangers they make poor guard dogs. They get along well with dogs and, other than some having a tendency to chase cats, they get along well with other family pets. Some still have herding instincts evidenced by prodding or nipping at heels. Shetland Sheepdogs are more sensitive than most breeds. They will react to loud noises and emotional turmoil in a household. They display an above energy level inside. Outside they are highly active but have only average exercise needs. Agile outside, they enjoy quick bursts of speed and are superbly graceful jumpers. Shelties require more companionship than most breeds and dislike being left alone. Doing so excessively will encourage their barking which may need controlled rather than encouraged. Additionally, some have a high-pitched voice which seems to amplify their barking. Poorly bred dogs may be excessively shy or high strung with some boarding on neurotic.

Shetland Sheepdogs look like miniature Collies. Small in size, their average height is 14-15 inches and they weigh between 14 and 27 pounds. They have a lush coat that comes the colors of sable (golden to mahogany), tricolor (black, white, and tan) and blue merle (grey, white, black, and tan). Grooming needs are less than most long-haired dogs. Brush them once or twice weekly to prevent matting except during their two annual periods of heavy shedding which occur in the spring and fall. Using an undercoat rake at this time will reduce shedding. They do equally well in both warm and cool temperatures.

A Shetland Sheepdog needs more than an average socialization effort to build confidence and increase their acceptance of new things. Highly intelligent, they are among the most trainable of all breeds. This can be a challenge for a beginning trainer as they pick up bad habits as quickly as what you intend to teach. Keep them mentally and physically stimulated. These ever attentive dogs are always learning. If you do not sufficiently engage them, they will train you, probably without your knowledge. Although not as demanding as a Border Collie or Australian Shepherd, if you are not interested in Obedience, Agility, Flyball, Pet Therapy, or other activities, then there are better choices than a Sheltie. But with an understanding of this caveat, they are a reasonable choice for a novice dog owner.
