I'm not sure how much help I'll be but here's our story.
I got a call a few years back from our rescue volunteer coordinator asking us to go down to the shelter right away. So,off we go,get there and she takes us back to the kennels to show us a "poodle mix" that was turned in for -get this-
his coat color not matching the new black microfiber furniture! She knew that he wasn't a mix (intake made their best guess). Anyway,"Baby Boy" came home with us that day-had his name changed to Cotton), he lives for my hubby (and vice versa!), loves anything that will get him dirty (changing oil in cars,working on lawn mower)! He has a totally offbeat sense of humor and has never met another dog that he won't try to be friends with. These dogs are just as much work coatwise as a full coat Yorkie.They don't shed hair all over but MUST be brushed out several times a week to get the loose hair out. They are super intelligent (a lot of old circus photo's show Bichons performing), Cotton has twice come to me and demanded that I go with him,once hubby had fallen (he's had multiple strokes) and the other time his sugar had gotten WAY to low. Both times Cotton came to get me on his own-hubby didn't send him! I know this sounds like a bad Lassie remake

but from talking to other Bichon owners it's completely normal behavior.
Another thing that he does all on his own is to "sit" with our other pets when they don't feel well,I have a Chihuahua who doesn't handle her yearly vaccines well at all. When Peanut get's her shots Cotton curls up beside her until her Benedryl wears off. He seems to think that he's the resident nurse! I could type for hours about him but hopefully you get the idea-LOL
Here's a pic of Cotton and our daughter,she takes him to work with her about once a month for his grooming(we take care of his normal bathing & brushing)

Not bad for a 2 yr old boy who was to be euthanized because he didn't match the furniture!
