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.
Hi Jenna, Female Dogs go into heat at any time between 6-12 months usually. The average heat cycle for a dog is approximately 3 weeks but for some dogs it is longer and for others it is shorter. Some as short as 10 days and some as long as 4 weeks or more. Usually your dog will go into heat every 6-7 months though again each dog is different and can go back into heat as early as 4 months or not for 12 months.
