🐾How do I read an OFA number?
Example: LR-100E24M-C-PI
LR = Breed code (Labrador Retriever in this case)
100 = Numerical ID given to each animal within a breed (in this example, it would be the 100th Labrador to be given a number)
E = Phenotypic OFA evaluation (E = Excellent, G = Good, F = Fair)
24 = Age (in months when testing was done)
M = S*x (This example = male)
C = Restraint type (C = Chemical, P = Physical Restraint, U = Type not provided)
PI = Identification: PI = Permanently identified (form of tattoo or microchip); if the attending veterinarian verifies permanent ID, VPI suffix is added; if no permanent ID, NOPI suffix is added.
