From the guide to your Lunamar records
The library explains breed and health concepts. The private platform organises dogs and kennels, preserves evidence, explores pedigrees and records reproduction. Reading a guide does not create records, grant access or confirm a result.
In Health and genetics, preserve the dog’s report and review variant, copies, inheritance and page before marking it Documented. A genetic finding, clinical suspicion and diagnosis are different facts. Recording a result does not prescribe treatment or automatically approve a mating.
For an individual dog, discuss tests and family history with the veterinarian. The system does not diagnose or decide treatment, ovulation or insemination timing. Missing data must remain identified as pending information.
