Ultrasound Scanning: Essential Information

Discover answers to the most common questions I’m asked about pregnancy scanning. This section explains the best time to book, how to prepare your dog or cat, what to expect during the appointment, and how scan results can support your next steps. It offers clear, practical support and reassurance throughout your breeding journey.

General Ultrasound Information

How safe is ultrasound scanning for mum and babies?
Ultrasound scanning is a painless procedure using high-frequency sound waves to produce images. The equipment used is CE approved, ensuring compliance with EU safety standards. Digital copies of the images are provided as keepsakes.
Is your service any different from using a vet?
Yes, the service focuses solely on domestic animal reproduction, offering specialized experience with hundreds of animals annually. Unlike some vet practices, this service avoids unnecessary shaving, allows owner presence during scans, and provides image keepsakes.
I’ve heard different people offer scanning. What makes your service consistent and trusted?
At HomeScan, every appointment follows the SARA System™, a four-step framework developed through years of experience and thousands of scans. This approach ensures each scan is carried out with structure, accuracy, reassurance, and clear next steps. It reflects the reputation we’ve built for offering reliable, informative, and supportive services that breeders and pet owners can trust.

Timing and Accuracy of Scans​

From what date is it best to scan?
For canines, between 28–35 days post-mating; for felines, 21–28 days. Scanning later is possible but may make counting foetuses more difficult due to development stages.
Can you date the pregnancy?​
While exact dating is challenging due to breed size variations, it's possible to estimate if the pregnancy is around 28–35 days or 45+ days. Measurements can provide estimations but are not precise.
How accurate is scanning and can it identify phantom pregnancies?
Accuracy depends on the sonographer's skill. Experienced professionals can detect phantom pregnancies, aiding in appropriate care decisions.
Can you provide numbers?
An estimation of the number of foetuses is provided when possible, but it's not guaranteed. This helps in pregnancy planning.

Pre-Scan Preparation​

What position does my pet need to be in for the scan?​
Pets can be scanned standing or lying down, based on their comfort. Cats are typically scanned belly-up in their owner's lap.
Does my pet need a full bladder like humans for the scan?
No, it's preferable for the animal to have an empty bladder before the scan.
Can I feed before a scan?
Feeding doesn't impact the scan, but an empty stomach might make the pet more comfortable during the procedure.

Alternative Pregnancy Confirmation Methods

Are there any other ways to confirm my pet is pregnant?​
Ultrasound is the safest and most accurate method. Other methods include:
  • Blood tests: Require a vet visit and don't indicate litter size.
  • Abdominal palpation: Possible between 21–35 days but not highly accurate.
  • Radiography (X-Ray): Can determine litter size from 45 days post-breeding but may cause distress and is typically used only if complications are suspected.
I’ve heard some animals can reabsorb; will this affect my pet?
Foetuses that die before 25–30 days post-ovulation are usually reabsorbed. Approximately 5–13% of canines may reabsorb one or more foetuses, which might have been identified in early scans.
