When do bitches come into season, and for how long? A bitchâs first heat cycle will begin when she reaches sexual maturity, which can vary from breed to breed and from dog to dog. The first season will usually begin between the ages of six months and two years of age, and will last for between two and three weeks. Left unspayed after the first season, bitches will continue to come into heat around twice a year, or once every six months.
