i think the standard is 4-7 lbs.. but the larger genes would follow the mom..
7 lbs is a good weight to breed mom ..
for breeding purposes.. some would say spay the 10 lb female and keep a female who is 6-7 lbs.
when trying to better the breed
the standards are used
the weight at 3 months will determine adult weight
it doubles .. 12 weeks 3lbs... one year 6 lbs..
less than 5 lbs for a female is too small to breed
show breeders are a good example to follow
