arentspowell has a lab and a mini doxie and as best I can tell, things are good with them. I think Lily, the dachshund, considers herself the boss of Daisy, the lab. You might be able to find some of their posts, I don't see her on too much these days.
If you scroll down to the 5th reply on this thread, she talks a bit about getting Lily.
maybe next year
