Short legs, heavy belly
In weeks eight and nine the weight of the litter can make walking awkward. Keep walks short, prevent jumping and support her when lifting.
Check the pelvis
The breed’s build can narrow the pelvic inlet. An X-ray around day 50 helps your vet decide between natural whelping and a planned C-section.
Typical timing
Gestation is about 63 days from ovulation. Take her temperature twice a day from day 56.
