Fig. 4

The relationship between frequency of searches per breed and dams registered. a A graph showing the base 10 logarithm of the number of searches per breed plotted against the base 10 logarithm of the number of registered dams per breed. The red line shows the trend obtained from the mixed-model smoothing spline fitted with Eq. (2), and the dashed line is the underlying linear trend of y = 1.109 + 0.827x. The white dashed line is y = x. The points shown in light blue are the EBV-track breeds, which had EBVs provided by The Kennel Club by the end of the study period. The labelled breeds from the convex hull and are: LR, Labrador Retriever; FB, French Bulldog; WFT, Wire Fox Terrier; RUSKY, Russian Toy; KAN, Turkish Kangal Dog; IBIZN, Ibizan Hound; NBUH, Norwegian Buhund; OTTER, Otterhound and BEARD, Bearded Collie. b A transformation of (a) where the y axis is now the number of searches as a multiple of the number of registered dams plotted against the log of the number of registered dams per breed. The red line shows the trend obtained from the mixed-model smoothing spline fitted with Eq. (2). The points shown in light blue are the EBV-track breeds, which had EBVs provided by The Kennel Club by the end of the study period. Labelled breeds are the same as in (a)
