I have 3 Bichons and yes you have to brush them each day but it does not take that long They can be hard to train although saying that all mine are rescue dogs
one is naughty and will steal anything from you handbag and you dont see him doing it but he is so lovable and cute
the other one is an older girl and she is so well behaved
last one is a 2 year old who will do anything you tell her
all 3 are toilet trained
i have in the past had bichon puppies and if you are at home all day with them i dont find them that hard to train at all
they love children and they love cats too at least all mine have
one thing is they do not like to be left alone for long periods of time
hope that helps
