What physical characteristic distinguishes the Redbone's selection criteria compared to the Treeing Walker Coonhound's emphasis on open ground running?

Answer

The Redbone breeders favored a build optimized for endurance in challenging terrain over sheer speed in open fields.

The Redbone’s divergence involved aggressively favoring the red coat and the specific stamina needed for diverse, difficult terrains, settling on a slightly smaller, leaner build optimized for endurance compared to the speed emphasized by the Treeing Walker.
