The Affenpinscher is a German ratter, developed to keep stables, kitchens and granaries clear of mice and rats. Its name means "monkey pinscher," a nod to the bearded, bright-eyed face. Adults usually weigh 7 to 12 pounds and stand 9 to 12 inches tall, with a shaggy, wiry coat that forms a mane around the head and shoulders, most often black.
Many Affenpinschers are confident, curious and a little comical, with more swagger than their size suggests. They tend to be loyal to their people, alert to every noise, and sometimes bossy with larger dogs. In Albuquerque, where big dogs and coyotes share trails and parks, that boldness is worth managing with a leash and good manners. Dogs vary, so judge each one by how it behaves.
