About this name and portrait

I'm sure you probably guessed by now. These aren't real pictures of these dogs. And these aren't their real names.

But these dogs were real. They were alive. They were loved. We thought they deserved more than a subject ID to be remembered by. The portraits are built from each dog's actual genome, so we tried to get it close. But it's not enough.

We want to see your dog's face. We want to celebrate them by the name they were loved by. We want to look back and say 'oh yeah, Bosco? The Dachshund-Corgi mix? I remember him, his FGF4 variant was wild, those little legs could hold a small house.'

These dogs gave something most people don't realize. The Heroes in the Golden Retriever Lifetime Study showed up for blood draws, health surveys, fur and nail samples, every single year. Some of them for 14 years. Their data has taught us about lymphoma, hemangiosarcoma, and aging in ways that help not just dogs but potentially humans. And they didn't ask for any of it.

Morris Animal Foundation calls them Heroes. We agree.

If your dog was part of any of these studies, we want to give you their page. Their real name. Their real photo. The recognition they earned.

About PFZ31A02_PFZ31A02

PFZ31A02_PFZ31A02 sits near the center of the Cavalier King Charles Spaniel cluster - genetically very typical for the breed.

Predicted medium by the six body-size genes the atlas reads (IGF1, HMGA2, SMAD2, LCORL, STC2, ADAMTS17).
Carries both copies of the FGF4 chondrodysplasia retrogene - the short-leg variant in Dachshund, Pembroke Corgi, Basset Hound.
Smooth coat. No wire-furnishings variant at RSPO2.

PFZ31A02_PFZ31A02's breed

PFZ31A02_PFZ31A02 sits firmly in the Cavalier King Charles Spaniel cluster.

Breed similarity from non-negative least squares against 91 breed centroids in PCA-256 space, corrected for atlas sample-size imbalance. Without correction, Goldens (22% of the atlas) leak into every dog's raw NNLS breakdown; with it, the bias falls out. Raw fractions stay in the dataset for re-derivation. Methodology.
