All of our puppies are played with dailyandlive in the house, under foot. They are use to the normal sounds in our home and hopefully yours. Neighbor kids come over weekly to visit and play with the pups and dogs. 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 include in the guarantee, only suggested based on past litters and weight charts. 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. Mygoalis 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. The moms are also good atteachingthe pups the art of play and the necessities of going to the bathroom. By the time they go to your home they are almost potty trained.They still need to be trained to the lifestyle ofyour home, which is something we can not do here.
