Canine Reproductive Health and Neonatal Viability
Summary
Canine reproductive health encompasses the physiological, genetic and management factors that influence fertility, gestation and parturition in the domestic dog. Successful whelping relies on maternal anatomy, endocrine balance and uterine contractility, while neonatal viability hinges on timely delivery, efficient respiratory adaptation and passive immune transfer. Breed-related conformational characteristics predispose certain bitches to dystocia, requiring vigilant monitoring and, in some cases, pharmacological or surgical intervention. Throughout pregnancy, regular ultrasonography and hormonal assays support accurate determination of foetal maturity and parturition timing. At birth, rapid assessment of puppy vitality—through Apgar scoring, umbilical cord blood gas analysis and temperature management—is critical to survival. Colostrum intake within the first 48 hours ensures passive immune transfer, while early detection of hypoglycaemia, infection or hypothermia guides supportive care. Advances in pharmacodynamics of uterotonic agents, refined neonatal assessment protocols and breed-specific growth curves contribute to improving survival rates and long-term welfare. The integration of veterinary expertise with breeder education underpins global efforts to reduce perinatal mortality and enhance canine population health.

Canine Reproductive Health and Neonatal Viability publication trend
The graph below shows the total number of articles in canine reproductive health and neonatal viability across all publications each year (not limited to Nature Index journals).
Technical terms
Dystocia: difficulty in labour arising from maternal, foetal or uterine factors that impede normal delivery.
Apgar score: a rapid assessment of neonatal health based on appearance, pulse, grimace, activity and respiration.
Passive immune transfer: acquisition of maternal antibodies by the neonate through colostrum ingestion shortly after birth.
Myometrium: the muscular layer of the uterine wall responsible for generating contractions during parturition.
Umbilical cord blood gas analysis: measurement of pH, oxygen, carbon dioxide and related metabolites in cord blood to evaluate neonatal acid–base status and oxygenation.
