Female Schnauzer dogs will go into heat for the first time about 6-9 months after birth, and they can become pregnant if they are bred at this time. However, it is recommended not to breed during this period, because the Schnauzer’s body functions are not fully developed at this time, and pregnancy is risky for the dog.
The earliest time you can breed a Schnauzer female dog is when she is 14 or 15 months old, which is when she goes into heat for the second time. At this time, the Schnauzer's body is relatively mature and can withstand the pressure of pregnancy. Adult Schnauzer dogs will have estrus once every spring and autumn, that is, around March-May and September-November, and the duration of estrus is uncertain. You can breed your dog during the period of heat.
The specific breeding time can be determined based on the Schnauzer's estrus performance. When the Schnauzer female dog is seen constantly approaching the male dog, the labia are swollen and everted, and the vaginal secretions change from red to yellow, and she is willing to accept the male dog. When climbing, you can start arranging breeding matters.
It should be noted that male Schnauzer dogs should not be allowed to mate frequently to avoid affecting the health of the dog. During the breeding period, the prime male Schnauzer can be allowed to mate once a day and then rest for 1-2 days. If there are two matings in one day, the interval between the two times should be more than 6 hours, and the male dog must be allowed to rest the next day. If there are certain needs that increase the number of breedings, more nutrition should be added to the dog. When a male Schnauzer is over 12 years old, do not breed him.
