Grading Criteria
-
The FCI hip dysplasia grading system has five classes ranging from A through E, each class having two levels, 1 and 2; A1 indicating no signs of hip dysplasia and E2 indicating severe hip dysplasia. The grades given are based on radiographs of the left and right hips. FCI standards mandate that dogs with hip dysplasia grades of D or E not be bred.
Formatting
-
An example of an FCI hip dysplasia ranking is HD-FCI: B1/2. The letters at the beginning are abbreviations for hip dysplasia and Federation Cynologique Internationale, respectively. The subsequent letter and number 1 or 2 are representative of the five classes and their corresponding levels.
Differentiation
-
If two numbers divided by a slash are displayed after the class letter of an HD identification, it indicates the radiograph grade of the left hip is different from the right. The B1/2 at the end of the grade represents a B1 grade for the left hip and a B2 grade for the right.
