What concrete structural difference relates to foot shape between the two breeds?

Answer

The Mini Foxie standard requires a compact and oval foot, while the Tenterfield standard allows for a round shaped foot.

Foot structure is noted as a concrete difference; the Mini Foxie explicitly requires an oval shape and states the foot should not be round, whereas the Tenterfield Terrier standard accepts either oval or a compact, round shape.
