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.
In fact, having your dog spayed before its first heat significantly reduces many health risks later in life. Can dogs become pregnant throughout the heat cycle? Dogs in heat initially resist mating, then actively seek a male and allow themselves to be mated. Dogs can become pregnant until the end of the heat cycle, which can last up to 24 days. Do dogs go through menopause? No; female dogs continue to go into heat throughout their lives, although the length of time between heats usually increases with older age. What is the best way to control the heat cycle? The best way to control the heat cycle is to have your female dog spayed.
