At Dgi Rotts we are proud of using ADRK Dogbase for all of our breedings bringing genetics and science into the art of selective pure bred dog breeding.

Here is a short explanation on how Dogbase works.

Dogbase: by Anton Spindler

Dogbase was developed during my term as a member of the ADRK Board, and as an organizer, mainframe systems/applications programmer, and a breed specialist I brought my fair share into the completion of this project for the ADRK and our Rottweiler breed.

DOGBASE includes all of the ADRK-Rottweilers along with their standard breeding values.

We have 6 values, figures above 100 show an increase in the value, figures below 100 show a decrease.

1 = HD

2 = ED

3 = undershot

4 = skull size

5 = cheek bones

6 = bone strength

As an example: If a dog shows for its Value 1 (HD) the number 115, statistically there is a greater chance of hip dysplasia in offspring of that dog. If a dog has in Value 3 (skull size) also 115, this means that he has a high probability of being dominant for larger skull sizes.

Very Important! As with any statistical evaluation, the results are only as good as the data used. These values must be interpreted with that in mind. If a dog has only been used once at stud, there will still be a value available, the value of relatives contributes to the value of individual dogs, so even a dog who has not yet been used at stud will show projected values. But if a dog had been used at stud 100 times, the numbers will be much more accurate. However, breeding will never be an exact science. Don't forget, there are lots of very good old breeders, who had great success with a good understanding of, and instinct about Rotts and some good common sense. DOGBASE is very helpful and I'm glad that we haveit, but it's not everything. Conversely, these days I personally couldn't imagine breeding without the additional input of DOGBASE.

DOGBASE requires an ADRK membership.

More.....from Dr. M. Herrmann (ADRK)

DOGBASE is both a database and a browser for all ADRK-Rottweilers born since the registration data was transferred to electronic processing in the mid 1980's. In addition the ancestors of these dogs, at least four generations back, are stored as well. All important information such as ancestors, name, stud book number, date of birth, breeder, hip and elbow score, stud tests (ZTP, Koerung), performance tests (SchH, IPO, AD, BH) and show titles are recorded. Dogs are indexed according to name or stud book number, and can be found easily. There are several ways to sort and extract data using keys such as time period, hip score, performance etc.

In order to improve breeding information there are six traits which are used for breeding value evaluation. Breeding values are given for informational purposes only, but you may be closer to the genetic truth. The breeding values given are no guarantee of the quality of future offspring, but may provide a better base from which to make breeding selections. To get an idea of inbreeding the index of inbreeding can be calculated for every dog. All ADRK-Kennels together with their breeding history are stored and can be found according to breeders' name, kennel's name or kennel's number.

The ADRK uses a computer database program called 'Dogbase'. Since July 1, 1999, ADRK breeders are required to use Dogbase as a tool for selecting the most suitable breeding partners. Dogbase is updated quarterly and is available on CD.

This database provides a numerical score in 5 categories: HD, ED, Head, Cheekbone, Bone strength . For every trait, "100" is neutral (average). A number higher than 100 means that a dog is more likely to exhibit that trait, a number lower than 100 decreases the likelihood of that trait. The first two categories (HD, ED) are the most important, they must not exceed 110 (if they are higher then the scheduled breeding is not allowed). The last three categories are "recommended". Optimally, for the first 2 categories the lower the number, the better. This means the dog is less likely to throw these traits. An example of a "good" HD number is around 95, a great one is around 85-90. It is not hard to find hips under 100, but good elbows (since they have only recently been examined) are more difficult to find. As a result, "100" is almost a good number for elbows, less than 100 is great and less than 90 is outstanding. For the last three categories, (Head, Cheekbone, Bonestrength), a higher number is better. Good bone strength is 110 and greater, with some numbers as high as 125. Head and cheekbone ratings are similar, anything over 110 is very good.

The numbers are dynamic, as the dog get its HD/ED ratings, its numbers will change and affect its parent's numbers (and further back), as well as its siblings. The numbers on a prospective (or already born) litter are simply the average of both parents until the offspring themselves get HD/ED ratings, Ztp / Koerung reports and show critiques.

Dogbase is a very interesting tool. It is no substitute for good research, but it is a huge step in the right direction. German bloodline dogs are superior because, in Germany, they take dog breeding seriously.
