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.
I am a fan of pretty much any dog that has naturally 'up ears' over 20lbs. I do prefer bigger dogs, my parents have an awesome German Shepherd, she's super sweet and well behaved.
I own 2 pembroke welsh corgis though and love them to death. I wanted a husky really bad, but I didn't realistically have the time to spend with one to keep it from destroyed my stuff plus its hard to find an apartment that allows them. I decided to get a corgi since I heard they do well in apartments, and would do OK with a shorter walk. 2 years later I had to have another, and they are great dogs and live up to their names. Sherlock is much more reserved and she isn't a big fan of new people, Watson on the other hand will greet anyone and immediately roll over for belly rubs.
