HOPEFULLY miniature dachshunds will NOT have very small litters- because that usually means very large puppies. But larger litters are equally difficult for the small breeds. It's very important to have proper vet care with ANY pregnant dog- but dachshunds are especially needy of it. If a litter is too large, c-section. If a litter is too small (and pups are thus large), c-section. Yes, c-sections are very common in the breed.
