The observed prevalence of CPSS was 0.8% (93 dogs), severe CTCS was 6.7% (739 dogs), and both conditions were 0.05% (6 dogs). The median age at diagnosis was 2.7\u00a0years (interquartile range [IQR], 1.0-5.7) for CPSS and 10.0\u00a0years (IQR, 8.0-13.0) for CTCS. The observed age-specific prevalence rate of both conditions (joint) in each age group was similar to the expected joint prevalence rates in each age group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Further investigation is needed to confirm whether there is a link between CPSS and the development of CTCS in Yorkshire Terriers.
