Scottish terriers are quite charming, even before considering their positive attributes. They’re short and stocky, standing at the maximum of 10 inches and weighing up to 22 pounds. Scottish terriers also have thick, colorfully rich coats that can keep them comfortable in colder climates. Personality-wise, scottish terriers are bright and aggressive, making them more suitable for homes without other dogs and children. They’re also occasionally stubborn, but loyal to their owners.
