Background
Origins and how that history shapes what you see today
Origin region
Wales
Background
Developed in Wales in the 1800s for going to ground on tough quarry, the Sealyham needed grit, strength, and a steady head. The breed later became rarer, but the temperament stayed sturdy and confident. Today, many Sealyhams are calm for a terrier, with a quiet stubborn streak that shows up when they’ve made up their mind.
Social & behavior
Temperament and interaction style
Personality & activity
Steady and confident with a calmer terrier pace. Often enjoys moderate activity and plenty of downtime, but can be quietly stubborn once decided.
Handling & social style
