We decided that Sandi should arrive first and let Coco get some of her exuberance out of her system before we shocked her with the arrival of another four-legged house guest. Coco has a greeting ritual she has patented that includes finding a gift for visitors (her choice of stuffed animals, pull toys, or anything handy), frantically whining her vocal joy with the "gift" clenched in her jaws, and a full aft body tail wag/prance routine that is charming but (we feared) waaaay over the top for quiet, sleepy, mild mannered Lucy. So get that out of her system and then bring in Lucy. That was the plan.
I followed a respectful few minutes later. With preplanned efficiency we introduced them still tethered; Sandi in the family room restraining Coco from her ritualistic greeting and me holding Lucy with the short leash. I swear they sensed each other before I ever got Lucy out of the car. When I entered the hallway Lucy was snorting like a bull and I could see and hear Coco whining and straining to meet (or attack, I didn't know which) the 65 Lbs of quivering white fur whose all four legs were skating in place on tile surfaced foyer in a desperate attempt to meet (or attack, I didn't know which) as I held on for dear life. It was all Sandi could do to restrain Coco and it was all I could do to keep Lucy back from charging into the family room. I advanced with Lucy as slowly as I could keeping a watchful eye in both dogs for rabies induced foaming at the mouth that seemed to be the imminent next stage of this clash of the Titans. Neither Coco nor Lucy cared for this dangerous game. They both growled and whined and displayed obvious (to us, at least) distaste for each other. They both wanted to smell the other but neither wanted the other to smell them in the area where dogs like to sniff each other. Sensitive for their personal space, I suppose. But the good sign was that both of their tails were wagging. We took that to be an optimistic sign that they did not have homicidal intentions. But it still was a scene of jousting like thrusts at each other with growls and snapping jaws when either one tried to sniff at the other's tail. I was beginning to think that I was going to have to take Lucy home and leave Sandi and Coco behind because the two of them were never going to reconcile to each other.
