N_t, all subjects in that cluster; N_s, subjects showing at least one of the signs in that cluster for a given principal component. Bold PCs are significantly different within the cluster, with different superscript letters identifying the source of difference,

^**p <0.01;

^***p <0.001. Italic values are the total number of dogs that presented at least one of the signs in that cluster for a given principal component.
