Aww, how cute! How about Ronan for a name? It's similar without you having to recycle a name, and I do love that "onan" sound. It's just perfect for a rottie.
My grandparents keep rotts, usually mixes. They gave up trying to find them at local shelters though because they were told that rotts were one of the breeds that the shelter had some sort of no chance policy on. Apparently the shelters aren't allowed to adopt out any rotts they take in, so it can be a hassle finding new dogs for my grandparents. They sure are worth the hassle, though. Sweet and loyal, looks that would scare away trespassers but with personalities like giant love sponges . . . um, well, more personality than a sponge, naturally, but I'm sure you know what I mean. Congrats!
