Obstetrics and Gynaecology in Cats and Dogs: Pregnancy Monitoring and Emergency Protocols

Medically reviewed by: Adem Fidan, DVM — Chief Veterinarian, Fidan Veterinary Clinic

At Fidan Veterinary Clinic pregnancy is confirmed by ultrasound at 25 to 30 days and litter size is counted by radiography after day 45. Labour is monitored, while emergency presentations such as dystocia and pyometra are stabilised and then managed surgically. Owners receive written guidance on the whelping box, temperature control and newborn care.

Pregnancy Monitoring and Birth Planning

At our Tatlıkuyu, Gebze clinic serving Darıca, Çayırova and Kocaeli, pregnancy in cats and dogs is confirmed by ultrasound at 25 to 30 days, when heartbeats and placental structures are assessed. After day 45, plain radiography reliably shows litter size and skeletal development for birth planning.

Energy and protein requirements rise over the final three weeks, so nutrition is adjusted accordingly. A mild drop in body temperature, nest building and restlessness signal approaching labour, and the owner is briefed in advance on the whelping box, a quiet environment and the emergency contact plan.

  • Ultrasound: pregnancy confirmation at 25 to 30 days
  • Radiography: litter size and skeletal detail after day 45
  • Mother and newborn check within the first 24 hours

Dystocia and Pyometra: Presentations That Cannot Wait

Strong straining for more than two hours, a visible puppy in the birth canal, green-black discharge or a delay beyond 24 hours indicate dystocia. Oxytocin is never given blindly in these cases; the birth canal is assessed and radiography performed first.

Pyometra is an emergency that typically follows oestrus and presents with fever, anorexia, increased drinking and discharge. Diagnosis combines ultrasound and blood work, and treatment is surgical once the patient is stabilised.

Clinical Pathway

  1. Gestational age and previous litter history are recorded.
  2. Ultrasound and radiography where indicated assess the litter.
  3. Labour is monitored, and the emergency protocol activates on delay or abnormal discharge.
  4. Mother and newborns are checked, with feeding and lactation follow-up planned.

Frequently Asked Questions

At what day can pregnancy be seen on ultrasound?

Gestational sacs may be visible at 18 to 20 days, but reliable confirmation and heartbeat assessment are best at 25 to 30 days. Scanning earlier can produce a false negative result.

Can I plan a home birth?

Uncomplicated pregnancies can be planned at home provided a prior check has been done, litter size is known and an emergency contact plan is ready. With straining beyond two hours or any delay, come to the clinic without waiting.

Is loss of appetite and increased drinking after oestrus normal?

No, that pattern raises concern for pyometra. Discharge may be absent while pus accumulates in the uterus, so ultrasound and blood work should be arranged without delay.
