Affenpinschers have a distinct appearance that some associate with terriers. They are different from terriers, however, in that they are actually part of the pinscher-schnauzer subgroup of group 2 in the FCI classification so often get along with other dogs and pets. They are active, adventurous, curious, and stubborn, but they are also fun-loving and playful. The breed is confident, lively, affectionate towards family members and also very protective of them. This loyal little dog enjoys being with its family. It needs consistent, firm training because some can be quite difficult to housebreak. The training should be varied because the dog can easily become bored.
