Viewed from the rear, the rear pasterns are straight and parallel to one another. A Tosa under the age of 12 months should not be penalized for standing with hocks turned slightly inward as this normally corrects with maturity. The feet are large, round, and tight. Pads are thick and elastic. Toes are well knuckled and nicely arched.
Rear feet are slightly smaller than front.
Nails are hard and preferably dark in color. Both front and rear feet should point straight forward. The seriousness of any of these faults is based on the degree of the defect. The tail is set on as a natural extension of the topline, and is thick and muscular at the base, tapering to the tip. A tail of the correct length extends to the hock.
