Most dogs will have two heats per year or an average of every 5-11 months. Some breed exceptions occur, such as the Basenji and Tibetan Mastiff, which typically only cycle once yearly. A dog’s first heat can start between the age of 6-24 months, with smaller breeds averaging earlier than larger breeds. The most notable sign of a dog’s heat cycle is bloody vaginal discharge, usually lasting between 14 and 21 days. Smaller breeds averaging earlier than larger breeds means that smaller breeds go into heat more often than larger breeds. Some breed exceptions occur, such as the Basenji and Tibetan Mastiff, which typically only cycle once yearly.

Some bitches can start their heat cycles as early as four months, however, this is unusual and is most common in smaller dog breeds. Larger dog breeds tend to start their heat cycles at around 8 to 12 months. After your dog’s first heat cycle, your dog will experience their next one every 6-7 months on average. This means a dog will be on heat twice a year. When your dog starts to mature in age, their cycles may become less regular. A dog will usually be on heat for anywhere between 2 to 4 weeks, and they are usually most fertile around day 10.
