Hey i have found a breeder close that I love...The mom of my pup is 7 pounds (short coat). They dad is 3.5 pounds (long coat). The litter was born easter sunday, there were four of them. They weighed in from 2oz-6oz. I get pick of the litter, i am so excited. They cant come home untill they are 10 wks. What do you think they will weigh at maturity? should i get a boy or girl chi?
