The Dobermann is driven, strong, and sometimes stubborn. With a consistent approach, they can be easy to train and will learn very quickly. They can easily learn to respect and protect their owners and are therefore considered by many to be excellent guard dogs. Given that they are properly socialized from a young age, they are generally sociable toward familiar humans and can also be sociable with other dogs. However, Dobermanns do rank among the more-likely breeds to show aggressive behaviour toward strangers and other dogs, though they are not among the most likely to do so. They are highly unlikely to show aggressive behaviour toward their owners. Why does my dog act that way?. Simon & Schuster.
