Will your chihuahua know how to have her first litter?

No, a chihuahua or any other dog will not instinctively know how to have her first litter or how to take care of her puppies. In the wild, dogs would learn from and depend on their parent to teach them these things, but when dogs are bred in captivity or by inexperienced breeders, they may not have access to this vital knowledge. While most female dogs have strong maternal instincts, the inexperienced will still need their human caregivers involved throughout pregnancy and while they raise their puppies to ensure the best outcome for all.
