The FCI standard calls it a small, long-haired working dog of great beauty and sets narrow limits on size. Ideal height is 37 centimetres for males and 35,5 for females; just two and a half centimetres above or below is highly undesirable. Small in a Sheltie therefore does not mean as small as you like.

Companion first, sheepdog second
The standard’s use section lists companion before sheepdog. It includes no historical account, only Great Britain as the origin; the FCI granted definitive recognition on 09.11.1954. Its appearance recalls the Rough Collie, but it is a separate breed with its own standard. A short coat is highly undesirable in a Sheltie under that standard.
Affectionate, but not everyone’s friend
Alert, gentle, intelligent, strong and active, affectionate and responsive to its person, reserved with strangers and never nervous: the result is a fine family dog that does not embrace every visitor.
A full-sized herding spirit in a small body
Its movement should cover the maximum ground with minimum effort. Long walks, agility, obedience or trick training suit it, and it learns quickly. Life purely as a lap dog would leave it underchallenged.
Mane, frill and breeches
The standard says the coat should fit the body without obscuring the dog’s outline. Brush two or three times weekly, thoroughly down to the skin, especially behind the ears and around the breeches. Plenty of undercoat comes out during shedding.
Medicines, gallbladder and hips
Shelties also carry the MDR1 variant that makes certain medicines dangerous: Washington State University gives a figure of around 15 per cent, while a German investigation found an allele frequency of 30 per cent (Gramer et al. 2011). Have your dog tested. A second concern is the gallbladder. In a clinical study of 38 affected Shelties, 25 had a gallbladder mucocele, with the condition discovered incidentally in 11 dogs (Aguirre et al. 2007). Have gastrointestinal symptoms in an older Sheltie checked promptly. In Sweden, roughly one in six of 651 dogs X-rayed had hip findings (15,7 per cent, Engdahl et al. 2026). At a median of 13,4 years, it outlives crossbreeds at 12,0 (McMillan et al. 2024).
Who the Sheltie is made for
People and families wanting a clever, affectionate dog keen to work, who enjoy training and make grooming a regular appointment. Beginners can manage well too.
Who should consider another breed
Very hectic households, anyone wanting a dog without brushing, and people who respond to reserved behaviour with pressure.
