Pregnancy Diagnosis and Monitoring for Dogs and Cats in Singapore
A suspected pregnancy in a dog or cat can raise important questions: Is the animal pregnant, how far along is the pregnancy, how many puppies or kittens may be expected, and is the mother well enough to carry the pregnancy safely?
At Allpets & Aqualife Veterinary Clinic in Singapore, our listed reproductive services include pregnancy diagnosis and monitoring. A veterinarian can assess the mother, recommend appropriate investigations and discuss monitoring or referral based on her health and the stage of pregnancy. The availability of specific tests should be confirmed with the clinic when arranging an appointment.
How Do Veterinarians Confirm Pregnancy in Dogs and Cats?
Pregnancy cannot be confirmed reliably from changes in appetite, abdomen size, mammary development or behaviour alone. These signs can have other causes. Veterinary assessment may involve a medical history, physical examination and imaging or laboratory testing where appropriate.
Pregnancy Ultrasound: When Can It Be Performed?
Ultrasonography is particularly useful for confirming pregnancy and assessing fetal viability. In dogs, a veterinary ultrasound is commonly informative at approximately 25–35 days of gestation. Scanning too early can give a false-negative result, and the appropriate timing depends on when ovulation or mating occurred. Ultrasound can help the veterinarian assess fetal heart activity and distinguish pregnancy from some other causes of uterine enlargement.
An ultrasound is not always the most accurate method for counting the final number of puppies or kittens, especially in larger litters. Its interpretation depends on gestational stage and imaging conditions.
Can an X-Ray Estimate the Number of Puppies or Kittens?
Veterinary radiographs may become useful later in pregnancy, once fetal skeletons are sufficiently developed. In dogs, radiographs taken late in pregnancy—often after approximately day 55—are generally more useful for estimating litter size than an early ultrasound. The veterinarian will consider whether radiography is warranted for the individual patient.
An estimated litter count can help owners and their veterinary team recognise whether all offspring may have been delivered, although no single investigation removes every uncertainty.
How Long Are Dogs and Cats Pregnant?
Pregnancy in dogs lasts around 63 days from ovulation, although counting from the date of mating is less reliable because mating and fertilisation do not necessarily occur on the same day. Cat pregnancy length also varies with the timing of ovulation and mating. Owners should not schedule an intervention based solely on a presumed due date.
Veterinarians may assess breeding history, clinical findings and gestational measurements to estimate the likely delivery period. Accurate dating is particularly important when a caesarean section is being considered.
What Happens During a Prenatal Veterinary Check?
A prenatal examination may include discussion of the mother's health, previous pregnancies, medications, appetite, nutrition and signs of illness. Depending on the findings, the veterinarian may recommend:
-
Pregnancy confirmation and assessment of fetal development
-
Monitoring of maternal body condition and general health
-
Selected diagnostic testing or imaging
-
Review of feeding, exercise and the home environment
-
Planning for delivery, newborn care and an emergency referral pathway
Medication, parasite prevention and supplements during pregnancy require individual veterinary advice. Do not introduce or discontinue prescription medication solely on the basis of general online information.
Does Every Pregnant Pet Need an Ultrasound?
Not necessarily. The need and timing of investigations depend on the animal's history, stage of pregnancy, breed, prior complications, symptoms and the decisions that need to be made. A veterinarian can advise which tests are likely to provide useful information rather than performing investigations routinely without a clear purpose.
When Does a Pregnant Dog or Cat Need Urgent Veterinary Attention?
Seek urgent veterinary assessment for collapse, severe weakness, marked pain, substantial bleeding, abnormal or foul-smelling discharge, repeated vomiting with significant illness, or suspected labour complications. If active labour has begun and delivery is not progressing, do not wait for a routine appointment.
Allpets & Aqualife is not a 24-hour emergency hospital. For an urgent reproductive emergency, call ahead to confirm immediate availability or proceed to an appropriately equipped emergency veterinary hospital.
Preparing for Whelping or Kittening
Before the expected delivery period, discuss the birthing environment, signs of normal labour, expected observation, and when to contact a veterinarian. Owners should know where to obtain emergency care outside the clinic's operating hours, particularly for pets at increased risk of difficult birth.

Frequently Asked Questions
When should I bring my dog for a pregnancy scan?
Ultrasound is commonly most informative around 25–35 days of gestation in dogs. A veterinarian can advise on timing based on the known breeding or ovulation history.
Can an ultrasound tell me exactly how many puppies my dog is carrying?
Not always. Ultrasound is especially useful for pregnancy confirmation and fetal viability. Late-pregnancy radiographs may provide a more useful litter-size estimate when indicated.
Can a dog appear pregnant without being pregnant?
Yes. Changes such as mammary development, nesting or abdominal enlargement are not definitive evidence of pregnancy. A veterinary examination can help determine the cause.
Do pregnant cats also need veterinary checks?
Veterinary assessment may be valuable when pregnancy is suspected, when the cat has underlying health concerns, or when there are questions about fetal health and delivery planning.
Can Allpets attend a pregnancy emergency overnight?
The clinic is not a 24-hour emergency hospital. For emergencies, call ahead to establish availability and seek an emergency veterinary hospital when immediate or after-hours care is required.
