Large litters are common. Strong maternal drive.
Large litters need a count
With up to twelve puppies, an X-ray after day 50 tells you when she has finished. Without it, a retained puppy is easy to miss.
Watch for a tired uterus
In a long labor the contractions can weaken. If she strains hard for 30 to 60 minutes with no puppy, or labor stops while puppies remain, call your vet.
Feeding for a big litter
Move her gradually to a high-quality puppy or growth diet from about week five and offer several smaller meals as her belly grows. Ask your vet about amounts for your dog.
