I am a small in home breeder. I'm breeding for health by eliminating The DVL-2 gene and the CDDY gene. I undergo hip and spine scoring, trachea measurements, NGR and RFG measurements. My dogs are adamts3 Neg and RFG scored. My single copy DVL-2 pups have a lateral spine xray at 8 weeks to confirm their spines have no congenital defects. I am an Emergency Nusre which is a great knowledge base for understanding scientific studies that support the removal of these genes for better health.
