Here is the thing: I got Cooper so Baxter would have a playmate (Ok and because he is cute too). Baxter was really devastated, for about 2 weeks, and then he accepted him. They do play together, but even Hubby says Cooper changed Baxter's personality. He became less playful, I think it is because Cooper is so dang competitive, and can run faster, so Baxter just gives up. If I sit on the floor to play fetch, Baxter lies in my lap, or brings me his bully stick to hold while I play with Cooper. That is the "special" time he wants! I think Baxter would have been A-ok with staying an only dog.
I think Rory will be fine with it, too. Especially since she gets all that great playtime at daycare!
Your special pup will come, in time, if it is meant to be, like you said
