I'm Sarah M., the breeder behind Cloud Nine Biewer Terriers located in Vacaville, CA. I fell in love with Biewer Terriers at a dog show and never looked back. Today our three Biewers compete in conformation and rally, with scent work next. We strive to raise well-rounded, healthy dogs and love proving that little dogs can do big dog things!
