You have 3 kinds of Dobermans I guess you would say. American , European, and the American/European cross. So you will have different size's and weights. But there are different standards in each of the countries.
The original German Standard (1899) Stated the Doberman Pinscher should be built muscular and powerful,but not clumsy and massy; neither should he be greyhound-like.His appearance must indicate swiftness,power and endurance. Temperament should be lively and ardent. Height at the shoulder: Males 21.6 to 25.6 inches; females 18.9 to 21.6 inches. Length from occiput to first joint of tail about 27.5 inches. Tail cropped, not longer than 5.9 inches. Head: Top of head must be flat or may be slightly arched, but the forehead must be broad; stretched long, the head must go over into a not too pointy muzzle. Cheeks must be flat but very muscular. A dog of about 19.7 inches in height at the shoulder should measure about 16 inches around the forehead. the length of the head, from occiput to the tip of the nose should be 9.9 to 10 inches. Ears cropped, not too short, not to pointy.
The American Standard (1982) The appearance is that of a dog of medium size, with a body that is square; the height, measured vertically from the ground to the highest point of the withers, equalling the length measued horizontally from the forechest to the rear projection of the upper thigh. Height at the withers: Males 26 to 28 inches, ideal about 27½ inches; Bitches 24 to 26 inches, ideal about 25½ inches. No weights are specified. But according to the AKC website the Weight should be from 60 to 80 #. For a complete profile on the AKC Doberman
The British Standard in most respects, the standard approved by the Kennel Club (of the United Kingdom) is similar to that of the AKC. There are some important differences that must be noted, Particularly involving the ears, as cropping is illegal in Great Britain. Ears should be small,neat and set high on the head. Erect or dropped, but erect preferred. Body should be square. Feet: All dewclaws to be removed. Ideal height: males 27 inches, females 25 1/2 inches. NOTE: In great Britain, this breed is known as the Dobermann.
The European dobermans are Larger. The European standard calls for the dogs of “Males: 26.8 to 28.3 inches. Bitches: 24.8 to 26.8 inches, with disqualification of 0.8inches over or under the standard. Weights from 70-120# For more info on the Differences in the American a & European breed This is another site that tells some about the differences.

Called Interesting facts about the Doberman
Now some people will claim they have a Warlock Doberman. Read Below what the DPCA has to say about the supposed Warlock Doberman."WARLOCK" Dobermans!! What IS a "Warlock" anyway???
Well, what I've been able to find out about this "Urban Legend" is that they are the "huge, giant form of the Doberman". Apparently, some years back there was a big demand, and there still is, by the way, for oversized Dobermans. People were wanting the extra big Doberman because they apparently wanted them larger, more like Great Danes.
Unfortunately for these people, the Doberman is a "MEDIUM" sized breed. The Doberman should NOT be oversized because the larger the Doberman becomes and goes beyond the ideal height of 27 1/2 inches at the shoulder for males, and 25 1/2 inches at the shoulder for females---they lose the agility and speed and the ability to turn and maneuver quickly.
These are all traits and qualities that are necessary for a guard dog that needs to be able to maneuver to protect and pursue, if necessary. The bigger the Doberman, the less maneuverability and quickness. Also, many of these so called "Warlock" Dobermans were actually offspring of Dobermans bred to Great Danes or Dobermans bred to Rottweilers---and not purebred Dobermans at all.
There was a Doberman male in the 1960's named Ch. Borong the Warlock. He was a very famous Doberman and many breeders bred their females to him. He had many offspring. Some reputable breeders that had this male in the pedigree of their good Dobermans advertised as having "Warlock" bloodlines. The "BYB" or BACKYARD BREEDERS, which are the ones that don't care about anything except making a quick "dollar" off of a litter of popular breed puppies, realized that this was a selling point for the good Dobermans that reputable breeders were producing and started using the phrase "Warlock" Dobermans to be synonymous with good Dobermans. The "term" became something that backyard breeders used to advertise their puppies. They used "Warlock" to mean better bloodlines, better Dobermans, bigger & better watchdogs---and so the term has been used for the last 20 years to basically mean a huge or giant sized Doberman---a rare and expensive kind of Doberman.
There are breeders today that continue to advertise to the public about having "Warlock" Dobermans. People think they are RARE, SPECIAL, MORE VALUABLE AND PAY LARGE AMOUNTS OF MONEY for these Dobermans. Please be advised---there is no such thing as a Warlock Doberman---other than what an exploiter or backyard breeder makes up.
The "WARLOCK" is a GIMMICK used to sell puppies. NO REPUTABLE BREEDER WOULD EVER ADVERTISE THEIR PUPPIES OR ADULTS AS "WARLOCKS". It is a MYTH and GIMMICK to sell Dobermans to the unsuspecting "PUBLIC". BEWARE of any breeder, advertisement or kennel that advertises "WARLOCK" Dobermans.
