Kallie's pups will be 3 wks tomorrow... When can I take the heating pad away? When will they start walking instead of slithering? When do I try them on solid food and how? All mine eat Chicken Soup for the Puppy lovers soul.. When will they start playing with us humans? Can I hold them alot? When can I introduce our new guy Percy, 3 months old, to the new litter and Kallie? When do they need another vet check up? Why do you not start shots until 8 wks? Can they go outside at all when they do start to run? Does anyone have a spare million dollars laying around??
