Scottish Terrier (Scottie, Diehard)

Weighing 18–22 lb (8.2–10 kg) and standing 10–10 in (25.4–25.4 cm) tall, the Scottish Terrier is a small-sized representative of the Terrier Group. It currently ranks #54 in AKC registration popularity. Its history begins in Scotland, where the breed was developed for its characteristic work. Many owners just call them Scotties. As with most breeds, males occupy the top of the size range.

How long do Scottish Terriers live? Based on published breed data, a typical lifespan is 12–13 years. Lifespan is influenced by size, since smaller dogs generally outlive larger ones, alongside genetics, body weight, dental care and regular veterinary checkups. Keeping a Scottish Terrier lean, exercised and current on preventive care is the most practical way to reach the upper end of that range. Against the average dog, small-sized breeds like this one sit on the longer-lived end of the spectrum.

This breed adapts well to apartment life when its exercise needs are met. The coat releases little hair, so lint rollers stay mostly idle. Plan on a middle-of-the-road grooming routine: weekly brushing plus trims now and then. No low-shedding claim applies here. Allergy sufferers should spend time with the breed before committing.

Expect medium energy — regular walks and a bit of active play go a long way. Most pick up basics readily but keep sessions short; boredom arrives quickly. Most do fine with respectful children, especially when raised together. Small animals can trigger chase instincts, so manage early introductions carefully.

Every number on this page is meant to be used, not just read. The calculators below start from this breed's 9.1 kg average weight, which in our 152-breed database sits heavier than 30% of breeds, and turn it into daily food portions, crate sizing and first-year budget estimates. Weight is the most consequential number in dog care economics, since portions, equipment and medication doses all scale with it. Data comes from the AKC breed profile cited below, and breed-specific health risks are exactly why comparing pet insurance early, while your dog is young and healthy, pays off.
