How Long is a Dog Pregnant?

Many people have heard about how a dog’s pregnancy lasts for sixty-seven days. The truth is, the term “dog months” has no bearing on gestation length. It merely means that it takes twice as many hours to reach adulthood as a human baby does. This is because a dog matures at two times the rate of a human being, which explains why they grow so much faster than humans do!

The average gestation period for dogs ranges from 63 to 68 days, with an average litter size ranging from 3-11 puppies. Pregnancy can be detected by looking out for hormonal changes in your pet’s behavior and physical appearance such as increased appetite and weight gain, lethargy or hyperactivity, nesting behaviors (such as the urge to create a nest for her young), and milk production. A veterinarian can then perform an ultrasound or x-ray to determine the age of your dog’s babies.

Depending on the breed, it is possible for a female dog to give birth twice in one year. Most are capable of breeding during their first estrus cycle after six months of age, but small breeds tend to reach sexual maturity over time, usually over eighteen months. Large breeds, on the other hand, will typically wait until they are about two years old before beginning to reproduce again.

However, spaying and neutering can be done at any stage in a dog’s life–it does not cause any type of health concerns when done at the appropriate time. Studies have shown that spayed or neutered dogs live longer lives and have a lower incidence of diseases associated with sexual hormones.
