when do french bulldogs go into heat the first time?
Female French Bulldogs experience heat cycles that are rather unpredictable and intermittent. Their usual heat cycle can last anywhere from 21 to 28 days, and they can be fertile anywhere from days 9 to 18, so it's best to keep them away from any males for up to 4 weeks... Some Frenchies have heat cycles as early as 6 to 7 months, and some can take up to 18 months to experience their first cycle...
Bulldog Information. Bulldog bitches can come into their first season anytime between 6 to 12 months of age. A bitch up to 12 months old is still considered as a puppy because she is in a growing phase and not fully matured yet. The recommended age for mating a Bulldog bitch for the first time is at the age of 12 to 18 month.
