Pregnancy is a normal physiological condition lasting approximately 63 days in dogs and cats, during which offspring develop within the uterus. While not a disease, it places significant metabolic demands on the mother and carries potential risks during labor.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately.
Report Case / Get HelpPregnancy occurs through mating during the animal's fertile estrus cycle. It is a biological process and not a transmitted disease.
The gestation period is divided into three trimesters. The first typically shows few signs; the second involves fetal growth and weight gain; the third is marked by distinct abdominal enlargement and nesting behavior as labor approaches.
Pregnancy is confirmed through abdominal palpation around day 28, or ultrasound to assess fetal viability. Late-term X-rays are the gold standard for counting the number of fetuses to ensure all are delivered safely.
Management involves high-quality nutrition formulated for growth or lactation. Regular prenatal checkups are essential. Medical intervention is reserved for labor complications (dystocia) or cesarean sections.
The only definitive prevention for pregnancy is spaying (ovariohysterectomy), which removes the reproductive organs. Preventing interaction with intact males during heat cycles is also effective.
A normal outcome is expected for most healthy pregnancies. Risks increase with breed-specific complications or if the mother is in poor health.
