This is the single most important health fact for the breed: Scottish Terriers have an estimated 18-20 times higher risk of bladder cancer (transitional cell carcinoma) than other breeds, a risk researchers suspect is linked partly to lawn chemical exposure — Purdue researchers use Scotties specifically for early bladder cancer detection studies given how strongly the breed is predisposed. Regular veterinary checkups and prompt attention to any change in urination are genuinely important for this breed specifically. Scotties are also prone to "Scottie cramp," a benign but dramatic muscle-stiffness condition triggered by excitement or stress, and mast cell tumors.
A quality diet with attention to leafy greens, which some research links to a modestly delayed bladder cancer onset in the breed — worth discussing with a vet given the breed's specific cancer risk.
The wiry double coat needs regular brushing and periodic hand-stripping or clipping to maintain its texture.
Scottish Terriers are independent and can be aloof — consistent, patient training works better than expecting eager compliance, and this breed's guarding instincts make early socialization worthwhile.
The Scottish Terrier ("Scottie") traces to the 13th-century Scottish Highlands, one of several terrier types bred for vermin control that were eventually split into distinct breeds — the Scottie among the oldest of Scotland's five native terriers, bred to work independently in packs away from direct human handling, which shapes the breed's characteristically aloof, self-possessed personality today.
Scotties have a genuinely notable list of famous owners, including US Presidents Franklin Roosevelt and George W. Bush and Queen Victoria — the breed's distinctive silhouette (low-slung, bearded, upright ears) has made it a recognizable cultural icon for over a century.
