What is the estimated adult weight?

One of the questions we get asked the most is about the “estimated adult weight” of the puppy. Most of our dogs mature in the 6 lb range.
Biewer Terriers and other toy breeds grow faster than larger breeds and stop growing between 9 to 12 months of age. Most of their growth happens between birth and 11 weeks.  To best predict the puppy’s estimated adult weight, we take their 6-week weight, double it and then double it again. A puppy who weighs 1.5 pounds at 6 weeks will weigh approximately 6 pounds as an adult (1.5×2=3, 3×2=6).

Please keep in mind that these are estimates and aren’t always accurate. You could end up with a bigger or smaller dog than you anticipated! We receive a lot of requests for so-called Teacup Biewer Terrier Puppies. Please know that the Biewer Terrier only comes in one standard size which can range anywhere from 4-8 lbs.  To indicate that a puppy’s estimated adult weight might be under 4 lbs.,  we call them “Mini” in some of our descriptions on the website. But there are no Toy Biewers or Mini Biewers, or Teacup Biewers as per the breed standard. The purchase price for certain puppies also indicates a dog puppy being on the small side as it takes much more effort to raise very small puppies.
