Characteristics

Appearance

Kennel club standards describe Doberman Pinschers as dogs of medium-large size with a square build and short coat. They are compactly built and athletic with endurance and swiftness. The Doberman Pinscher should have a proud, watchful, determined, and obedient temperament.The dog was originally intended as a guard dog, so males should have a masculine, muscular, noble appearance. Females are thinner, but should not be spindly.

Color

Two different color genes exist in the Doberman, one for black (B) and one for color dilution (D). There are nine possible combinations of these allelles (BBDD, BBDd BbDD BbDd, BBdd, Bbdd, bbDD, bbDd, bbdd), which result in four different color phenotypes: black, red, blue, and fawn (Isabella). The traditional and most common color occurs when both the color and dilution genes have at least one dominant allele (i.e., BBDD, BBDd, BbDD or BbDd), and is commonly referred to as black or black and rust (also called black and tan). The red, red rust or browncoloration occurs when the black gene has two recessive alleles but the dilution gene has at least one dominant allele (i.e., bbDD, bbDd). "Blue" and "fawn" are controlled by the color dilution gene. The blue Doberman has the color gene with at least one dominant allele and the dilution gene with both recessive alleles (i.e., BBdd or Bbdd). The fawn (Isabella) coloration is the least common, occurring only when both the color and dilution genes have two recessive alleles (i.e., bbdd). Thus, the blue color is a diluted black, and the fawn color is a diluted red. 

Expression of the color dilution gene is a disorder called Color Dilution Alopecia. Although not life threatening, these dogs can develop skin problems. 

In 1976, a "white" Doberman Pinscher was whelped, and was subsequently bred to her son, who was also bred to his litter sisters. This tight inbreeding continued for some time to allow the breeders to "fix" the mutation. White dobermans are a cream color with pure white markings and icy blue eyes. Although this is consistent with albinism, the proper characterization of the mutation is currently unknown. The animals are commonly known as tyrosinase-positive albinoids, lacking melanin in oculocutaneous structures, but no known mutation has been identified. 

Tails 

The Doberman Pinscher's natural tail is fairly long, but individual dogs often have a short tail as a result of docking, a procedure in which the majority of the tail is surgically removed shortly after birth. 

The practice of docking has been around for centuries, and is older than the Doberman as a breed. The putative reason for docking is to ensure that the tail does not get in the way of the dog's work. Docking has always been controversial. The American Kennel Club standard for Doberman Pinschers includes a tail docked near the 2nd vertebra. Docking is a common practice in North America, Russia and Japan (as well as a number of other countries with Doberman populations), where it is legal. In many European countries, docking has been made illegal, and in others it is limited. 

Ears 

Doberman Pinschers often have their ears cropped, as do many other breeds, a procedure that is functionally related to breed type for both the traditional guard duty and effective sound localization. Like tail docking, ear cropping is illegal in some countries, and in these pictures Doberman Pinschers have natural ears. Doberman Pinscher ear cropping is usually done between 7 and 9 weeks of age and is done under anesthesia. Cropping done after 12 weeks has a low rate of success in getting the ears to stand. 

In some countries' conformation shows, Doberman Pinschers are allowed to compete with either cropped or natural ears. In Germany a cropped or docked dog cannot be shown regardless of country of origin. Special written exception to this policy does occur when Germany is the location for international events.
