I think Shilling is lonely, and I don't want to wait so long that he gets used to being an only dog and gets snooty when we bring someone new in. He's very energetic and happy and I think he deserves a friend that will play with him. Puzzle was always far too dignified to deign to take much notice of him.
It's not writ in stone yet. Mum's writing back to Sandy and saying she'd like Esc Key and Shilling to meet. Usually when we say we'll come take a look though, we end up bringing the Scottie home that day.
