Terrier is a type of dog rather than a single breed. The name comes from the Latin word for earth, because these dogs were developed over several centuries to hunt rats, foxes and other vermin, often by following them into burrows. Dozens of breeds share the label, and dogs listed simply as terriers are usually small to medium mixes with wiry or smooth coats.
Most are lively, confident and loyal, with big personalities for their size. Barking, digging, chasing small animals and an independent streak are common habits. In Skokie, that means a secure fence or a leash on walks, a plan for noise in shared buildings, and patient, reward-based training. A dog's size, coat and energy depend on its ancestry, so meeting the dog tells you more than the label.
