Caro - No matter what I ended up deciding (to trim or not to trim) I would definitely brush out the dog often. I really enjoy brushing dogs and will love having an outlet for that again! It's nice to know that it's not really a mortal sin, though may not be as effective as I'm imagining...
Diana - I have considered the Pap. Very tempting and some lovely Pap breeders down here, but my future dog will need to spend a good amount of time with people of all ages, including small children, and I'm currently thinking the Pap may be a little small for that. (For this reason I'm really iffy on the Iggy, too...)
I have two Shelties and one Papillon. Pierre (the Papillon) was the first dog. He is small (8 lbs) but well suited to playing with children. He has never shown fear or violence toward the young or the elderly. However, the Shelties are naturally reserved in new situations. Pierre DOES bark when he feels like it and can be quite vocal. Usually it is adorable - like a soft growl from the couch that says "come snuggle me!!" If you want a velcro-snuggle dog that can be trained athletically and is too smart for their own good, you would make a great Papillon owner. Another plus is that he is literally wash-and-wear. I brush him once a week unless he's going through his twice a year shed (then its everyday unless I want a black and white couch). We're going on at least 6 weeks since his last bath and someone who met him yesterday complimented how he smells.
Drawbacks are the extreme stubbornness, lack of level of devotion of a Sheltie (they love but do not do things to please you like a Sheltie does), and difficulty to housetrain.
If you have any other Pap questions, I'm here!


It's good you are thinking it through and considering other breeds first, though.
