ChessieInfo Database
This database represents several decades of effort on the part of many. The dogs in this database are those with titles or health clearances, along with as many of their ancestors as can be traced. An ongoing effort has been made to include as many dogs, from as many countries, as time allows. Definitions of title abbreviations appear here.
You can access the database here.
I am continually updating this database as more information becomes available. If you do not see a dog in the database that you feel should be included, or if you find an error, contact me at faralloncbr@yahoo.com.
ChessieInfo Frequently Asked Questions
Why does it take so long for my dog to show up? The length of time it takes for a dog to appear in the database will vary. Title reports are received from AKC monthly. These reports contain dogs who have earned titles two to six months prior to the report being generated. OFA and CERF generate quarterly reports. If your dog just recently earned an AKC title, or an OFA or CERF number, be patient. The information will show up eventually.
What are the numbers in parentheses behind some dogs' names? To reduce the number of duplicates, the ChessieInfo database is indexed to the dog's names. This means that no two dogs may have the identical name. However, our breed has a long history and uses several different registries. Some dogs do have the same registered name, particularly rescue/ILP/PAL dogs. Therefore, I place the year of the dog's birth, stud book year, or other identifying number behind the identical names, so that they I can tell those dogs apart. This increases the accuracy of pedigrees. As parenthetical numbers are not an official part of a dog's registered name, feel free to remove these when producing pedigrees for puppy buyers, etc.
How are OFA and CERF numbers Indicated? OFA hip numbers in the database are all standardized to the format: CB-0000E24M-PI where 0000 is the number of the dog’s certificate, E is the letter designation of the dog’s evaluation (Excellent, Good or Fair) 24 is the dog’s age at the time of the evaluation in months, M or F is the dog’s gender, and PI is the dog’s identification status. Earlier numbers have a T, indicating "tattooed", but with the advent of microchip identification, OFA updated their identification codes. These are now PI for Permanent ID, VPI for veterinarian verified ID, and NOPI for no permanent ID. Currently, OFA only accepts tattooes and microchips as permanent identification on their forms.
Other OFA database numbers are given prefixes: CB-EL for elbows, CB-TH for thyroid, CB-DM for degenerative Myelopathy, CB-SH for shoulder OCD, CB-CA for cardiac clearances, CB-PRA for PRA, CB-PA for patellar luxation, and CB-EIC for exercise induced collapse.
CERF numbers have the standard format CB-0000/08-25, where 0000 is the certificate, 08 is the last year CERFed, and 25 is the age of the dog in months when the examination was performed. Re-CERF exams are denoted by an asterisk after the number, CB-0000/08-25*.
Other hip and eye certification data are also found in the database. To see more information on these databases, click here.
What is that percentage behind my dog's name? That is a Coefficient of Inbreeding, or COI. A COI is an indication of how inbred a particular individual is. As the COI is calculated based on the number of times dogs appear in your dog's pedigree, they may or may not indicate that a dog is genetically inbred. A high COI is an indication that the dog may be more inbred, but not necessarily so. Likewise, dogs with low COIs can be very homozygous for many traits, indicating a lack of genetic diversity, even though on paper the dog is not inbred. COIs in this database are calculated to ten generations.
Why does my dog's COI change some times? The COI is calculated based on names that appear in the pedigree. I am always checking older data against newly acquired official sources; sometimes I find errors, especially when two dogs have the same name. After errors are corrected, the COI is recalculated using the new pedigree information. As Chessies have a very tight gene pool, even pedigree clarifications from the 20's and 30's can affect COIs of modern-day dogs.
