Summarize the following:
The American Kennel Club (AKC) describes the temperament of the Doberman as energetic, determined, watchful, loyal, and fearless. This goes some way to describe the alert intelligence of the Doberman. When channeled correctly through good training, their energy and willfulness make them a potent working dog and a great pet. Due to the size and power of the Doberman, if its handler is not knowledgeable and confident, the dog has the potential to become dangerous. The Doberman is not a suitable breed for a first time owner. Indeed, the ideal owner should be an experienced dog owner who is prepared to devote time and attention to the correct training and exercising (both mental and physical) of their dog. If this happens then a Doberman is likely to be a wonderful, attentive, and loyal companion who is devoted to their owner.  In the wrong hands a Doberman (through no fault of its own) could become either fearful (and therefore aggressive in order to protect himself from perceived threats) or territorially aggressive. Neither is a desirable scenario an out of control doberman is a danger to life and limb. A well-trained Doberman can make a great family dog, but supervision is essential around small children as this dog is very energetic and if a small child gets in the way, the dog may push them over. Being a large dog, and an athletic one at that, Dobermans need adequate space to move around. Apartment living is not a great option for a dog this active and large unless you will give it enough exercise for your dog to spill out all of its energy. And of course, make sure your land lord allows dog, do not try to hide a dog, ever! Indeed, the Doberman also needs access to a decent sized yard, in order to stretch its legs between walks. This yard should also be fenced, as a Doberman may become defensive if a stranger wanders over its territory; keep in mind these dogs were specifically bred to protect. You should be prepared to devote at least 2 hours a day to exercising your Doberman, an hour in the morning and again in the evening. Their working origins and athleticism mean they have a high requirement for exercise. You should weigh the costs associated with keeping any large dog. You need to provide a good quality food, since cheap foods bulked up with cereal may ferment in the dog's gut and predispose it to bloat. Obviously good quality foods are more expensive than that cheap food, and the cost of feeding the required amount can be considered. Also, deworming and anti-parasite treatments are going to cost more than for a small dog. The Doberman should stand around 24 - 28 inches tall at the shoulders, with males being taller than females. The classic color is black with tan markings, but red, blue, and fawn are also permissible by the AKC. The Doberman weighs 60 - 80 lbs and the average lifespan is 10 - 13 years. In the US the ears are usually cropped, while in the UK this procedure is considered a cosmetic mutilation and frowned upon.
