When does a Schnauzer go into heat? The first heat is about 8-11 months after birth. After adulthood, it goes into heat once every spring (March-May) and autumn (September-November). However, due to living together with humans, the superior material conditions have affected the seasonality of Schnauzers, showing the phenomenon of being in heat all year round. However, spring and autumn are still the times when Schnauzer dogs are more concentrated in heat.

The estrus period of female Schnauzer dogs is a cycle of 6 months. The initial estrus period is 6 to 10 months after birth, but once the estrus period ends, male dogs are not allowed to mate with them. They are not suitable for mating before the next estrus period in a 6-month cycle.

Male dogs do not have a special estrus period. If they are sexually mature 6-8 months after birth, they can mate at any time. Once stimulated by the scent of a female dog in estrus, it will want to mate with her.

If your Schnauzer has many obvious changes in its body and behavior, including increased excitement, increased activity, restlessness, loud barking, and bright eyes, these are signs that the Schnauzer female dog is in heat. If the bitch’s butt exudes red mucus accompanied by blood, then you can be sure that your dog is in heat.
