In small animal reproduction, medical pregnancy termination protocols in the bitch employ:
Aglepristone (RU534, competitive progesterone receptor antagonist, gold standard) (A)
PGF2α / Dinoprost (natural luteolytic prostaglandin) (B)
Dexamethasone (oral high-dose glucocorticoid causing luteolysis and feto-placental disruption) (C)
Dopamine agonist (Cabergoline, which suppresses luteotropic prolactin) combined with synthetic prostaglandin (Cloprostenol) (D).
All four protocols (A, B, C, and D) are recognized and used clinically. Thus, option 3 is correct.

In veterinary obstetrics, Presentation is defined as the spatial relationship between the longitudinal axis of the fetus and the longitudinal axis of the maternal birth canal (longitudinal anterior/posterior, transverse, or vertical), along with the portion of the fetus leading into or presenting at the internal pelvic inlet. Position refers to the relation of the fetal dorsum to the maternal pelvis, and Posture refers to the disposition of fetal extremities (head, neck, limbs).

Carnivores (dogs and cats) lack seminal vesicles (vesicular glands). In dogs, the prostate gland is the only accessory sex gland present, while both vesicular and bulbourethral glands are completely absent. In contrast, bulls, boars, and stallions possess well-developed seminal vesicles.
