1. A pet diaper extending in a lateral direction along a waist of a pet and in a longitudinal direction from a ventral side to a dorsal side of the pet, the lateral direction being orthogonal to the longitudinal direction, and the pet diaper comprising:
a main body including:
an absorbent core; and
a tail hole having a longitudinally elongated shape with a largest opening width in the longitudinal direction that is larger than a largest opening width in the lateral direction;
a pair of fastening tabs, disposed closer to the ventral side than is the tail hole, that extend outward from a lateral side edge of the main body; and
a target portion, disposed closer to the dorsal side than is the tail hole, that engages with the pair of fastening tabs, wherein
a dorsal side edge of the tail hole is disposed on the ventral side with respect to a middle point between:
a lateral center line of the main body perpendicular to the longitudinal direction, and
a ventral side edge of the target portion,
a distance in the longitudinal direction between a ventral side edge of the tail hole and the lateral center line is shorter than a distance in the longitudinal direction between the dorsal side edge of the tail hole and the middle point,
an opening width of the tail hole in the lateral direction continuously narrows from the dorsal side edge of the tail hole toward the ventral side edge of the tail hole,
a dorsal side edge of the absorbent core is disposed on the ventral side with respect to the ventral side edge of the tail hole, and
a distance in the longitudinal direction between the ventral side edge of the tail hole and the dorsal side edge of the absorbent core is shorter than a distance in the longitudinal direction between the dorsal side edge of the absorbent core and the lateral center line.
