"PeerJ Preprints" is a venue for early communication or feedback before peer review. Data may be preliminary.

Supplemental Information

Figure 1. Examples of the variation in coat phenotype and mass/height (M/H) ratio for the breeds considered in this study

The dogs in the first row are all sight hounds, a group defined by its adaptations for high speed running (Fischer & Lilje, 2011). The dogs in the second row are other breeds not thought to be adapted for feats of great running speed.

Figure 2. The association between coat phenotype and morphology conducive to high speed running in 51 larger dog breeds

The mass/height ratio (y-axis) is used as a proxy for morphology conducive to high speed running (smaller values indicating a greater adaptation for high speed running). Breeds that lie towards the right of the figure are increasingly shaggy.
