Should i Get this Dog?

For the past 7 months or so i have been trying to figure out the perfect dog for me. I have narrowed it down, and this is one of the finalists...

The Doberman Pinscher

"Doberman Pinschers are very keen, super energetic with tremendous strength and stamina. Dobes like to be with their people and are not suited to kennel or back yard life, they need human interaction and leadership. Loyal, tolerant, dedicated and affectionate with the family. Determined, bold and assertive while working, they are very adaptable, highly skilled and versatile. They are intelligent and very easy to train. They are an outstanding watch and guard dog and do not need additional protection training. This breed is not for everyone. The Doberman needs an owner who is willing and able to display a natural authority over the dog. All family members must be firm, confident and consistent, setting rules and sticking to them. Learning to handle the dog properly, as Dobermans can become stubborn and willful if allowed to have their own way. Everything must be on the humans terms. The dog is the follower, and the humans are the leaders. The dog will appreciate knowing his place in his pack and feel secure about it. He should be thoroughly socialized when young to prevent skittishness. Mental stimulation and a lot of daily exercise is important in order to produce a happy, stable minded Dobe. The Doberman needs to be consistently and thoroughly trained. Dobes can be good family dogs if the alpha role belongs to the human and if they receive enough exercise, are well trained and are socialized with children. Although the Doberman has the reputation of being a very aggressive dog, this is just not the case. For example, Dobes make great therapy dogs. Issues arise when they reside with owners who do not display the proper leadership and or do not provide enough exercise. They are sweet and gentle with nursing-home patients - tippy-toeing over IV tubing and walking at the resident's speed (which can be very slow), while at the same time will fiercely defend his master if it becomes necessary. Dominancy levels vary, even within the same litter and the breeds temperament will vary greatly depending on how well the owners understand canine behavior and how willing they are to take the time to provide what the dog instinctually needs.
