approximately how long before a female puppy go into season
A bitch generally has her first estrus season, or heat, at between 6 and 12 months of age, most commonly between 8 and 10 months. Mating will produce a litter at this age, but she is immature, so it is important to guard against that potential. A female dog will normally return to season about every six months. Some have estrus seasons as often as every four months or less. If you are not a serious breeder, the healthiest thing you can do for your female puppy is to spay her before she reaches sexual maturity, according to the PetMD website.
While many females will hold to a fairly steady schedule of coming into season about every six months, it can vary. Some girls will only come into heat once year, while others may even come into season every four months. However, these extra seasons are not always fertile.
