However, it's important to remember that:
* This is just an average. Some litters may be smaller or larger.
* Factors like the age of the mother dog and her overall health can influence litter size.
* Breeders will often monitor the pregnancy closely and may use ultrasound to get a better estimate of the litter size.
If you are considering getting a Miniature Schnauzer puppy, it's best to talk to a reputable breeder to get more information about their breeding practices.
