Quick Answer. A female dog goes into heat again between 4 and 6 months of having her puppies. The non-spayed dog goes into heat twice a year, and this is known as estrus. The estrus cycle lasts between 12 and 21 days but often varies between breeds and dog size.
Though dogs can become pregnant at any point once theyâre mature, itâs best to wait until your dog is at least two years old before breeding. For some breeds, like Boxers, you want to wait until they are at least three years old. Simply put, you want your dog to be fully mature before they have puppies. Not only will this ensure the safety of mother and puppies, it will also make the process of raising the puppies easier. Once mature, a female dog goes into heat approximately every 6 months. The cycle of heat lasts around 3 weeks at a time. Many female dogs skip heat cycles during their lives.
