Border Terriers are small to medium-sized dogs. Males typically weigh between 11 to 15.5 pounds, while females usually weigh around 11 to 14 pounds. They stand about 10 to 11 inches tall at the shoulder.

Border Terriers are known for their friendly, affectionate, and spirited nature. They are intelligent and eager to please, making them relatively easy to train. While they are generally good with children and other pets, their strong prey drive may lead them to chase smaller animals. Socialization at an early age is key to developing a well-rounded temperament.

Border Terriers have a dense, wiry double coat that is weather-resistant. The outer coat is rough, while the undercoat is softer. They come in various colors, including grizzle and tan, red, or blue and tan. Regular grooming is needed to keep their coat in good condition and to minimize shedding.

Border Terriers thrive in active households where they can engage in plenty of exercise and mental stimulation. They can adapt to various living environments, including homes with yards or apartments, as long as they receive regular opportunities to play and explore.

Border Terriers enjoy a range of activities, including walks, hikes, and play sessions. They excel in dog sports such as agility, obedience, and earthdog trials, which cater to their instincts. Providing interactions that challenge their intelligence, such as puzzle toys and training exercises, is also beneficial.
