The short answer
AKC’s general breed weight chart lists 11–20 pounds for Miniature Schnauzers. The official conformation standard, however, defines the breed’s size by height and overall proportion rather than a single required weight. A puppy’s eventual weight varies with frame, age, muscle, diet, and health.
What this means for your home
For your dog, ask your veterinarian to assess body condition instead of chasing a number from an advertisement. You should be able to discuss growth and feeding with the breeder and vet, especially for dogs marketed as smaller “toy-sized” Miniature Schnauzers.
Three useful takeaways
- Use adult parent weights as context, not a warranty.
- Track growth with your veterinarian.
- Avoid overfeeding to reach a number—or underfeeding to stay below one.
