How Long After a Dog’s Heat Bleeding Does Ovulation Occur?

A female dog generally ovulates on day 2 to 3 of her heat bleeding. Her heat period is the ovulation period, starting around day 2 to 3 and stopping when heat ends. During heat she drips blood, which is the bleeding. Heat usually lasts 7 to 14 days, with the highest conception rate on days 11 to 14, so if you plan to breed her, arrange mating then.
