When does the heat start in French Bulldogs? - in detail
The onset of heat, or estrus, in French Bulldogs typically begins between the ages of 6 to 12 months, although it can vary depending on several factors. The first heat cycle is often referred to as "puppy heat" and may not be accompanied by ovulation, which means the dog is fertile but may not become pregnant even if mated during this initial cycle. Subsequent heat cycles usually occur every 6 to 8 months thereafter, with most French Bulldogs experiencing two heat cycles per year. It's important to note that individual variations exist among dogs, and factors such as overall health, diet, and environmental conditions can influence the timing and regularity of these cycles.
