Hi, do you know of any breeders in the uk who breed miniature maltese dogs. I have been looking everywhere but so far have no luck except to go to america?

The reason you've had no luck is that it's a non-existent breed! There is only one size of Maltese. Anyone who claims to breed 'miniature Maltese' is producing runts, who are likely to be unhealthy and cost you a fortune in vet's bills. Contact the breed clubs listed at the bottom of the link and ask for details of reputable breeders.
