Progressive Retinal Atrophy in Shetland Sheepdogs

Clinical overview

Why Shetland Sheepdogs carry elevated Progressive Retinal Atrophy risk

Shetland Sheepdogs are predisposed to progressive retinal atrophy relative to many mixed-breed dogs, driven by conformation and heritable risk. Early detection and a dated care timeline materially change outcomes for this breed. Keep symptoms, diagnostics, medications, and surgical notes together so every caregiver sees the same Progressive Retinal Atrophy history.
