The Terrier Group is a classification of dog breeds known for their energetic and feisty nature. These dogs were originally bred for hunting and burrowing, making them skilled at chasing small animals like rodents. They typically have a strong, compact build and a distinctive coat that can vary in texture and color. Terriers are known for their intelligence and tenacity, often displaying a strong desire to dig and explore. Popular breeds in this group include the Jack Russell Terrier, Scottish Terrier, and West Highland White Terrier. Their lively personalities make them great companions, but they require regular exercise and mental stimulation.
