The new pup and our oldest pup made friends!!! I had been planning on how I'd introduce them. Walked up to the gate leaving Pup and the oldest pup at the new pup's kennel. When I walked back Pup, the new pup, and the oldest pup were in the same enclosure. No fussing at all from the New Pup and the Old Pup just growled alittle when new pup sniffed her but. Old Pup rules the kennels so this is really good.
