Hi,
You will do well to find any breeders in Scotland - I gave up and twice have ventured south of the Border for my Pups.
Try the Scottish Kennel Club in Edinburgh for a list of registered breeders - the service costs about a fiver or so for the list and I think can be purchased online.
or try the Bichon club of GB

Keep searching the end result is worth it
