DNA and the AKC

Making the Science Work for You The AKC offers a comprehensive set of voluntary and mandatory programs to ensure the integrity of the AKC registry: voluntary DNA Profiling; the Frequently Used Sires requirement; the Fresh-Extended/Frozen Semen requirement; the Multiple-Sired Litter Registration Policy; the Import Breeding Stock requirement; and the Kennel Inspections/Compliance Audit Program. The AKC has built the world's largest database of canine DNA profiles for parentage verification and genetic identity purposes.

The Science Behind AKC DNA Profiles
AKC DNA Profiles are generated using the same technology used by law enforcement agencies throughout the world. How does this work? In humans and dogs alike, each gene is present as two copies (displayed as letters). Offspring receive one copy of each gene from each parent in a random process.This technology does not use actual genes, but other DNA sequences that are also inherited one copy from each parent. For this reason, your dog's AKC DNA Profile does not provide any information about the conformation of the dog or the presence/absence of genetic diseases. Furthermore, AKC DNA Profiles cannot determine the breed of a dog.

Voluntary DNA Profile
This voluntary program has resulted from significant input from the fancy. The DNA Profile Program is for owners and breeders electing to add value to their breeding programs by eliminating concerns or questions about identification and parentage.

A dog owner may contact AKC for a DNA Test Kit which includes a swab that the owner uses to collect loose cells from inside the dog's cheek. An AKC DNA Profile containing the dog's registration information, genotype, and a unique DNA Profile number is issued for each dog sampled. This DNA Profile number will appear on subsequently issued Registration Certificates and Pedigrees.

DNA Requirements
AKC DNA Profiling is required for: Frequently Used Sires (dogs having the greatest impact on the AKC Stud Book); imported breeding stock; dogs whose semen is collected for fresh-extended or frozen use; and for the sires, dam and puppies for Multiple-Sired Litter Registration.

Kennel Inspections/Compliance Audit Program
AKC Representatives take DNA samples at randomly selected kennels to verify identification and parentage of litters. AKC litter registration and privileges will be withdrawn when the parentage of the litters is determined to be incorrect. The dogs sampled through the Compliance Audit Program are not considered AKC DNA Profiled, and DNA Profiles are not issued.

The AKC DNA Database and Parentage Verification
Comparison of the DNA profiles of a dam, sire, and pup(s) will determine, with greater than 99% confidence, whether the pups are from the tested dam and sire.The AKC DNA database examines the parentage of all AKC DNA Profiled registered dogs and litters whelped on or after January 1, 2000. When problems are discovered, the DNA staff works with breeders to determine correct parentage at the breeder's expense.

AKC Parentage Evaluation Service
For a fee, an AKC DNA Analyst will issue a Parentage Evaluation of a litter in the form of an easy to read table listing each dog's genotype and a written report.Parentage Evaluation can be used to ensure accuracy when breeding has been done offsite, for cases of artificial insemination, or to add an extra measure of confidence to your pedigrees.

AKC Parentage Profile
For AKC registered dogs born on/after January 1, 2000, dog owners may purchase a handsome profile displaying the registration information and genotypes for the dog and its AKC registered sire and dam. All three dogs must be AKC DNA Profiled to purchase this profile.

Rottweiler History

Rottweiler History
The origin of the Rottweiler is not a documented record. Once this is recognized, actual history tempered by reasonable supposition indicates the likelihood he is descended from one of the drover dogs indigenous to ancient Rome. This drover dog has been described by various accredited sources as having been of the Mastiff-type-a dependable, rugged, willing worker, possessed of great intelligence, and a strong guarding instinct.The transition from Roman herding dog to the dog we know today as the Rottweiler can be attributed to the ambitions of the Roman Emperors to conquer Europe. Very large armies were required for these expeditions and the logistics of feeding that number of men became a major consideration. No means of refrigeration existed which meant that the meat for the soldiers had to accompany the troops "on the hoof." The services of a dog capable of keeping the herd intact during the long march were needed. The above-described "Mastiff-type" was admirably suited to both that job and the additional responsibility of guarding the supply dumps at night.Campaigns of the Roman army varied in scope, but the one of concern to us took place approximately A.D. 74. Its route was across the Alps terminating in what is now southern Germany. Arae Flaviae, as the new territory was called, had natural advantages of climate, soil, and central location. There is much evidence pointing to the vital role of the fearless Roman drover dog on this trek from Rome to the banks of the Neckar River.We have no reason to doubt that descendants of the original Roman drover dogs continued to guard the herds through the next two centuries. Circa A.D. 260 the Swabians ousted the Romans from Arae Flaviae, taking over the city. Agriculture and the trading of cattle remained their prime occupations, insuring the further need for the dogs.About A.D. 700 the local Duke ordered a Christian church built on the site of the former Roman baths. Excavations unearthed the red tiles of Roman villas. To distinguish the town from others, it was then named das Rote Wil (the red tile), which of course is recognizable as the derivation of the present Rottweil.Rottweil's dominance as a cultural and trade center increased unabated, and in the middle of the 12th century further fame and fortune came to it. An all-new town with elaborate fortifications was built on the heights above the river. The security thus provided increased commerce in cattle. Butchers concentrated in the area and inevitably more dogs were needed to drive the cattle to and from the markets.The descendants of the Roman drover dog plied their trade without interruption until the middle of the 19th century, at which time the driving of cattle was outlawed; in addition, the donkey and the railroad replaced the dog cart.The Rottweiler Metzgerhund (butcher dog), as he came to be called, then fell on hard times. His function had been severely curtailed and in those days, dogs earned their keep or there was no reason for their existence. The number of Rottweilers declined so radically that in 1882 the dog show in Heilbronn, Germany reported just one poor example of the breed present.The annals of cynology make no further mention of the breed until 1901 when a combined Rottweiler and Leonberger Club was formed. This Club was shortlived but notable because the first Rottweiler standard appeared under its auspices. It is of value for us to know that the general type advocated has not changed substantially and the character called for, not at all.In these years (1901-07) the Rottweiler again found favor as a police dog. Several clubs were organized as dissension was most common until 1921 when it was agreed to form the Allegmeiner Deutscher Rottweiler Klub (ADRK). By that time, 3,400 Rottweilers had been registered by three or four clubs. Duplications and confusion ended when the ADRK published its first stud book in 1924.Since its inception, despite the difficulties encountered during and in the aftermath of World War II, the ADRK has remained intact and through its leadership enlightened, purposeful breeding programs have been promoted both in Germany and abroad.
