A female dog’s first heat usually lasts 7 to 14 days. The first heat typically comes at 7 to 8 months, then recurs about every six months, twice a year, though some dogs start earlier or later.
During heat, put dog diapers on her to keep the home clean, and wipe the vulva regularly to prevent infection.
