Good advice from kita, also remember that they are non moulting so will need to be taken to a professional groomer every six - eight weeks to be clipped unless you are willing/able to learn to do it yourself, and that can cost anything from 25 - 60 pounds a time. Clippers can cost
about 50 - 100 pounds plus sharpening, oil, brushes etc.
The correct name is Bichon Frise.
