Gear sizing for a Borzoi
The "gather supplies" milestone on your timeline lands two weeks before the due date — here's what that shopping list looks like sized for a typical Borzoi (60–105 lb):
- Whelping box: 5 × 4 ft with pig rails. Mom needs room to stretch out fully with space left for the litter; the entry lip should be low enough for her to step over comfortably at full term but high enough to keep newborns in.
- Crate: 48 in — her quiet retreat near the whelping area during the final weeks, and the safe way to travel to the vet for the X-ray and any delivery-day drive.
- Collar 22–26 in, harness XL: late-pregnancy walks should be gentle, and a well-fitted harness avoids pressure on her midsection entirely.
Buy before the final-two-weeks crunch — the timeline's supplies milestone exists because whelping boxes in particular sell in odd sizes and ship slowly. Sizes above are typical retail ranges for the breed; a pregnant dam near term can need a size up from her usual, so measure her, don't guess.

About 63 days from breeding, the same as every breed — gestation length doesn't vary meaningfully by breed. The normal range is 57–65 days.
How many puppies does a Borzoi usually have?
A typical Borzoi litter is 6–9 (typical for this size) puppies. An optional final-week X-ray (after day 55) gives the real count for your litter.
What size whelping box and crate for a Borzoi?
For a typical Borzoi (60–105 lb), plan on a whelping box around 5 × 4 ft with pig rails and a 48 in crate for mom. Collar 22–26 in, harness size XL. Sizes are typical retail ranges — measure your own dog before buying.
How long are dogs pregnant?
About 63 days from breeding on average, with a normal range of 57–65 days. Gestation length does not meaningfully differ by breed — a French Bulldog and a Great Dane carry for the same two months.
When can a vet confirm my dog is pregnant?
A relaxin blood test can confirm from roughly day 22–27 after breeding, and an ultrasound between days 25–35 shows fetal heartbeats. Early negatives can be false — recheck a week later.
When should I take an X-ray to count puppies?
After day 55, when fetal skeletons have calcified. The final-week X-ray gives a reliable count so you know when whelping is finished.
