In addition to all Keeshonds being PHPT negative (either by descent or tested) The Keeshond Club and the North of England Keeshond Club both recommend that all breeding Keeshonds are to be both hip and elbow scored prior to mating and in addition advise that all Keesies are eye tested at some point.
Both Breed Clubs also fully support the Keesworld Pedigree website as it contains much more complete Keeshond pedigree than does the UK Kennel Club. As more complete generations of ancestry are included in this database, the COIs generated will therefore be much more reliable.
