What physical feature of the Yakutian Laika hints at the excellent lung capacity required for its high-output working life?

Answer

A deep chest

The physical structure of the Yakutian Laika is built specifically to support strenuous, high-output work over long periods. A critical component supporting this requirement is the chest structure. They possess a deep chest, which is a physical indicator suggesting excellent lung capacity. This enhanced respiratory capability is vital for dogs expected to maintain a sustainable pace and exert themselves continuously across unforgiving Arctic terrain where energy conservation and continuous oxygen supply are paramount for endurance, contrasting with breeds built solely for power or sprint.
