They claim to but, I bought two "miniature dogs" that were supposed to only be 4lbs to 6lb turned out to be more like 10lbs to 12lbs.
Haven't seen micro dogs maybe as small as a yorkie prices vary a couple thousand
Looking for a mini pin just lost mine after 14 years
I saw a cute female blonde chihuahua that would have grown to maybe 9 lbs myself being sold.
