A dog pedigree is a family tree, and once you understand the layout, every name, abbreviation, and notation tells you something specific about a dog’s lineage, achievements, and health. Whether you’re evaluating a puppy from a breeder or researching your own dog’s background, here’s how to decode what you’re looking at.
How the Chart Is Laid Out
A standard pedigree reads left to right. Your dog (or the dog being evaluated) sits on the far left. Moving right, each column represents one generation further back. A three-generation pedigree shows parents, grandparents, and great-grandparents. A five-generation pedigree goes two steps further, listing 62 ancestors total.
The top name in each pair is always the sire (father), and the bottom name is the dam (mother). So directly to the right of your dog, the top entry is your dog’s sire and the bottom is the dam. Moving one more column right, the top two names are the sire’s parents (his sire on top, his dam below), and the bottom two are the dam’s parents. This pattern repeats through every generation. Once you internalize “top is sire, bottom is dam,” the entire chart clicks into place.
What the Titles and Abbreviations Mean
Most names on a pedigree are surrounded by abbreviations, and these represent titles the dog earned in competition or testing. They fall into two categories based on where they appear relative to the dog’s registered name.
Prefix titles appear before the name and typically indicate conformation (show ring) achievements. The most common is CH, meaning Champion, which means the dog earned enough points at conformation shows to finish its championship. GCH stands for Grand Champion, a higher tier. FC (Field Champion) and DC (Dual Champion, meaning both a conformation and field title) show up in sporting and hound breeds.
Suffix titles appear after the name and cover performance events and companion programs. Some common ones:
- CD (Companion Dog): Earned by qualifying at three obedience trials in the Novice class.
- JH (Junior Hunter): Earned by qualifying at four hunting tests.
- NA (Novice Agility): Earned by qualifying at three agility trials.
- CGC (Canine Good Citizen): A temperament and manners certification.
A dog with many titles on a pedigree has been tested in multiple venues. When you see titles stacked across several generations, it suggests the breeder has consistently proven their dogs in competition, not just bred for appearance or paperwork.
The Registered Name vs. Call Name
Every dog on the pedigree has a formal registered name, which is often long and includes the breeder’s kennel name as a prefix. For example, “Crestview’s Thunder at Sunrise” tells you “Crestview” is the kennel that bred the dog. Some pedigrees also list the call name (the everyday name, like “Max”) in parentheses, but many don’t. The kennel name is useful because it lets you trace which breeding program produced a given dog, and whether the same kennel name appears repeatedly in the pedigree.
Color Coding and Formatting
Many printed and online pedigrees use visual cues to highlight important information. Names in bold or red often indicate a dog that earned a championship or other significant title. On pedigrees used for genetic analysis, dogs affected by a specific health condition may be shaded in solid, unaffected dogs left open, and known carriers shaded half-and-half. If you’re looking at a breeder’s custom pedigree, ask what their formatting conventions mean, since there’s no universal standard for color choices.
Health Clearances and Test Results
Responsible breeders often include health testing results on pedigrees, either printed directly or referenced by certification number. The most common system in the U.S. comes from the Orthopedic Foundation for Animals (OFA). Hip evaluations are graded as Excellent, Good, or Fair for passing results, abbreviated as E, G, or F in the OFA number. Elbow evaluations follow a similar system. These grades tell you whether a dog’s joint structure was evaluated by a veterinary radiologist and found to be within normal range.
Genetic (DNA) test results for breed-specific conditions typically appear as one of three statuses: Clear means the dog carries no copies of the disease mutation. Carrier means the dog has one copy and won’t be affected but can pass it to offspring. Affected means the dog has two copies and will develop or has developed the condition. You might see these abbreviated as “PRA: Clear” or “DM: Carrier,” where PRA and DM are shorthand for specific eye and spinal conditions. A pedigree showing health clearances across multiple generations gives you much more confidence than clearances on the parents alone.
Spotting Repeated Names
One of the most important things to look for is the same dog appearing more than once in a pedigree. This is called linebreeding (when done intentionally) or inbreeding (when the repeated ancestor is very close). If a grandparent appears on both the sire’s and dam’s side, the offspring has inherited genetic material from that individual through two separate paths, increasing the chance of getting two identical copies of any given gene.
This is measured by the coefficient of inbreeding, or COI. A COI below 5% is generally considered healthy. Between 5% and 10%, you start to see modest negative effects on vitality and immune function. Above 10%, the Institute of Canine Biology notes significant risks: more expression of harmful recessive mutations and reduced overall health in the offspring. Many online pedigree databases calculate COI automatically when you input a dog’s registration number. The more generations included in the calculation, the more accurate the number, since a distant ancestor appearing on both sides still contributes to inbreeding even if they’re five or six generations back.
Reading International Pedigrees
If you’re looking at a dog imported from another country, the pedigree may come from the FCI (Fédération Cynologique Internationale), the umbrella organization that oversees kennel clubs in most countries outside the U.S. and UK. FCI pedigrees use many of the same conventions but with different title abbreviations. A dog from Germany, for instance, will have an “Ahnentafel” (the German word for pedigree) issued by the breed club, along with a separate export document.
The UK’s Royal Kennel Club requires a certified Export Pedigree for imports, or at minimum a three-generation pedigree certificate from countries that don’t issue export papers. Title abbreviations vary by country: a German “SchH” indicates protection dog training, while a Finnish “JK” might indicate a show result under FCI rules. If you’re evaluating an international pedigree and don’t recognize the abbreviations, the issuing country’s kennel club website will have a title list similar to the AKC’s.
Putting It All Together
When you sit down with a pedigree, work through it in layers. First, orient yourself with the layout: find your dog on the left, identify the sire and dam, and trace the generations to the right. Second, look at titles. Are there championships and performance titles throughout, or just on one or two dogs? A pedigree loaded with titled dogs across several generations suggests consistent quality. Third, check for health clearances. Look for OFA ratings and DNA test results on at least the parents and grandparents. Fourth, scan for repeated names and ask about the COI. A breeder who can tell you the COI and explain why they made a particular cross is a breeder who understands what the pedigree actually means.
A pedigree isn’t just a piece of paper for registration. It’s a map of genetic probability, and the more fluently you can read it, the better decisions you’ll make about breeding, purchasing, or simply understanding your dog’s background.
