Neonatal viability in dogs is directly associated with appropriate parturition management and early intervention in obstetric disorders. Singleton Puppy Syndrome is characterized by the presence of a single fetus, resulting in insufficient uterine distension and failure to trigger the physiological onset of labor, which may lead to primary uterine inertia, fetal distress, and increased perinatal mortality. This study reports a case of Singleton Puppy Syndrome in a bitch undergoing timely cesarean section, emphasizing the importance of basic neonatal resuscitation in reversing neonatal depression. A bitch with prolonged gestation and absence of labor signs underwent cesarean section following ultrasonographic and radiographic diagnosis consistent with a singleton fetus and high obstetric risk. The neonate presented an initial Apgar score of 2, and basic neonatal resuscitation procedures were immediately initiated, including active warming, airway clearance, tactile stimulation, oxygen therapy, and stimulation of the GV26 acupoint. Progressive improvement in neonatal vitality was observed, with the Apgar score increasing to 9 within 60 minutes, ensuring the puppy's survival. It is concluded that early diagnosis of Singleton Puppy Syndrome, timely surgical intervention, and the systematic application of neonatal resuscitation protocols are critical factors for improving neonatal survival in high-risk cesarean deliveries.
