This win is notable since it is the first time this breed has won Best in Show at Westminster. Affenpinschers have a distinct appearance that some associate with terriers. 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 is also very protective of them. This loyal little dog enjoys being with its family. Affenpinschers are somewhat territorial when it comes to their toys and food, so they are not recommended for homes with very small children. This dog is mostly quiet, but can become very excited if attacked or threatened, and shows no fear toward any aggressor.
