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.
Puppies can produce puppies as soon as they start their first heat at 6 to 8 months of age. But it's very unhealthy for a dog at that age to have puppies. You'll need to wait â¦ until after her third or fourth heat cycle. She'll be just over 2 years old by then. At the age of 2 years is when a dog is fully matured and can be tested for genetic health defects prior to breeding. If you do plan on breeding always find a male that is smaller than your dog.
