Sunny lived in the 1980’s. Way before we had all this early cancer. Back in the days when hip certifications were the only clearances we needed. However, although we do not have heart,eyes and elbow clearances…we have 50 years of pedigree history that proves this was a VERY sound and healthy pedigree with longevity. We still have frozen semen from Sunny that we use to bring back health and longevity to this breed!
