All of our babies are played with daily and live in the house, under foot. They are use to the normal sounds in our home and hopefully yours. This is part of our socialization process.
Most all our pups will be in the 3 to 6 pound range as an adult. Occasionally, there are some that are a bit smaller, and maybe even a bit larger. We won't be able to guess their adult size until we can see their growth pattern. Their adult weight is not included in the guarantee.
At about 4 weeks we start taking them outside to learn the smells of outside and to learn to go to the bathroom out there. My goal is to get them excited to go outside. Since all our dogs live in the house with us (as he will at yours when he goes to live with you), it is a big thing for us to get them to want to learn to potty out there, as well as, play or go for walks. They still need to be trained to the lifestyle of your home, which is something we can not do here.
