The Importance of DNA Testing in Responsible Breeding

By Hidden Legacy Kennels

DNA testing has transformed the world of dog breeding. We break down exactly what we test for, what the results mean, and why it matters for your puppy's long-term health — from CMR1 and HUU to DM and the dilute markers that define our rarest colorations.

Why We Test

DNA testing is the foundation of responsible breeding. It allows us to identify carriers of genetic conditions before they're ever part of a pairing.

What We Test For

  • CMR1 — Canine Multifocal Retinopathy
  • HUU — Hyperuricosuria
  • DM — Degenerative Myelopathy
  • Dilute markers — Confirming the genetics behind our rarest colorations

What Results Mean

A 'carrier' result doesn't mean a dog is sick — it means they carry one copy of a recessive gene. By ensuring carriers are only paired with clear partners, we can prevent affected puppies while preserving genetic diversity.

Our Commitment

Every HLK parent completes a full DNA health panel before they're ever part of a litter. Full transparency, every time.
