To find a reputable Breeder, start with the BICHON FRISE CLUB OF CANADA. Start phoning and emailing all the member/breeders listed. Ask questions and see if that breeder knows someone planning a litter. Ask them who they would recommend in your area. It will be tedious but will hopefully pay off in the long run.
Attending "All Breed" dog shows in your area, may also turn up a bichon exhibitor, who may be breeding in the future. This is a good chance to see their dogs up close after the show and ask questions.
