Affenpinscher
Even though Affenpinschers were bred to hunt mice, they do not like to chase other animals, so they can happily live with other pets. They are playful but very stubborn. These dogs can be difficult to train, because they do not like to listen to instructions and often become bored. Affenpinschers are somewhat territorial (protective) when it comes to their toys and food, so they are not recommended for homes with very small children.
