Doberman Pinscher

The Dobermann to most of the world, or Doberman Pinscher as it is known in the US and Canada, is a medium-large breed of domestic dog originally developed around 1890.
Traditionally, the ears are cropped and posted and the tail is docked. However, in some countries it is illegal to do so. Dobermanns have markings on the chest, paws/legs, muzzle, above the eyes, and underneath the tail.
Dobermanns are well known as intelligent, alert and tenaciously loyal companions and guard dogs. Personality varies a great deal between each individual, but if taken care of and trained properly they tend to be loving and devoted companions. The Dobermann is driven, strong and sometimes stubborn. Owning one requires commitment and care, but if trained well, they can be wonderful family dogs. With a consistent approach they can be easy to train and will learn very quickly. As with all dogs, if properly trained, they can be excellent with children.
The Doberman Pinscher has ranked among the most intelligent of dog breeds in experimental studies and expert evaluations.
The Doberman Pinscher, along with the Border Collie, German Shepherd, Golden Retriever, Standard Poodle and Rottweiler, is one of the most trainable breeds of dog.
Although they are considered to be working dogs, Dobermanns are often stereotyped as being ferocious and aggressive. As a personal protection dog, the Dobermann was originally bred for these traits: it had to be large and intimidating, fearless, and willing to defend its owner, but sufficiently obedient and restrained to do so only on command. These traits served the dog well in its role as a personal defense dog, police dog, or war dog, but were not ideally adapted to a companionship role. The Dobermann's aggression has been toned down by modern breeders over the years, and today's Dobermanns are known for a much more even and good natured temperament, extreme loyalty, high intelligence and great trainability. In fact, the Dobermann's size, short coat and intelligence have made it a desirable house dog. The Dobermann is known to be energetic, watchful, fearless and obedient.
They can easily learn to 'Respect and Protect' their owners and are therefore considered to be excellent guard dogs that protect their loved ones. They are generally sociable toward humans and can be with other dogs. However, Dobermanns rank among the more-likely breeds to show aggressive behavior toward strangers and other dogs, but not among the most likely to do so. They are very unlikely to show aggressive behavior toward their owners.
