There’s a lot of nuance with dog pregnancy, so we’ve created this handy guide to help you navigate. The “heat season” begins around 6 months of age, on average, for unspayed female dogs.
If she is bred on the day the oocytes can be fertilized, her gestation length will appear to be 60 days long. During gestation, many physiological changes are similar to other mammals like humans. This results in similar shifts in nutrients in the blood of dogs, especially affecting glucose, fatty acids (like DHA) and amino acid (like BCAA ...
Ovulation occurs 24–48 hours after the luteinizing hormone peak, which occurs around the fourth day of estrus; therefore, this is the best time to begin breeding.

As of 2019, only contraceptives are commercially available.
