I'm Ronald G., the breeder behind Canosia Tollers & Australian Shepherds located in Duluth, MN. We are responsible breeders who are passionate about our dogs! They’re central to our lives, and we are proud of their accomplishments. We strive to maintain breed standards, good health, and well adjusted temperament (a dog you can live with in your home & enjoy for years to come!). We participate in conformation, obedience, rally, barn hunt, scent work, dock diving, agility, and hunt tests/classes with our Nova Scotia Duck Tolling Retrievers and conformation, agility, and obedience with our Australian Shepherds. We are members of the ASCA and NSDTR clubs.
