I like Corgis (preferably Cardigan Welsh), Dobermans, Irish Wolfhounds, Leonbergers, and anything fluffy, cute, and well behaved. Pomeranians and such are adorable, but I hate when they're yappy and irritable. Makes me sad to see a cute dog that's poorly trained.
I also like Cavalier King Charles Spaniels. My brother's friend is lucky enough to have taken in a stray one. He's adorable! Great Pyrenees and Samoyeds are very pretty dogs as well, as are Longhaired German Shepherds.
I think my favorite dogs of all may be the Rough Collie and the Shetland Sheepdog. I've always wanted either one of those, but sometimes I don't think I'd be up to the task of owning/training a dog with so much energy (and hair)! If I did get one, I'd probably be more likely to get a Sheltie though.
