Many experienced breeders believe that a female dog goes into heat for the third time, but some dogs go into heat every 4 months, so we should wait until at least 21 months old, which is about 2 years old. . In Germany, a female dog cannot give birth to puppies if she does not meet HD standards and has not obtained breeding qualifications. When meeting these requirements, she must be at least 2 years old.
The cycle of female dogs in estrus is 4.5-5 months, and the maximum is no more than 6 months. Of course, season and weather also play a big role. The estrus period of a female dog has a lot to do with the surrounding environment and climate patterns. If you want to breed female dogs, you should accurately record the time and days of each estrus in order to calculate the ideal pairing time.
Generally speaking, the ideal breeding time is the 12th day after the female dog is in estrus. Some individual female dogs are in estrus for only 12-14 days, which is another matter.
Some dogs can be bred on the 6th to 7th day of estrus, and some dogs will not let male dogs touch her before the 16th to 17th day of estrus. Therefore, there is no unified law. Breeders must keep accurate records themselves, at least knowing the number of days each time their dog is in estrus.
Experienced breeders believe that when the female dog’s blood becomes light red and thin, It’s ready for breeding. Some people think that when the owner strokes the base of the female dog's tail or pubic area, and the female dog's tail actively moves sideways, it is a sign that the dog is ready for breeding. These methods are effective in most cases, but if you rely solely on them, the best time for breeding will sometimes be delayed.
The safest way is to use a male dog to test the female dog’s reaction. If the female dog takes the initiative to tease the male dog and puts her tail sideways, she is ready for breeding.
