Terrier is a label for a group of dogs developed over several centuries to hunt vermin, often by following prey into burrows. Dozens of breeds share the name, from tiny Yorkshire Terriers to the much larger Airedale, and listings often use it for small to medium mixes whose ancestry is unclear. Wiry, smooth and silky coats all appear, so shedding and grooming differ from dog to dog.
Most terriers are confident, affectionate and loyal, with a stubborn streak and a tendency to bark, dig and chase small animals. Those habits matter in Salem, where apartment living, secure yards and rainy-season mud all come into play. A DNA test or a veterinarian's opinion can hint at ancestry, but the dog's own behavior, age and energy tell you more than the label.
