About Us


Our love affair with the Australian Shepherd began prior to 1996 with the purchase of our first Aussie, Pete. For more than 20 years, we have been actively involved with the breed, titling our dogs in all venues, including conformation, herding, rally, obedience, agility, etc. In addition to Canadian Kennel Club events in the western provinces, we attend the ASCA National in the US every year and have enjoyed many successes in the ring, with multiple Top 10 Premieres and First place wins.  

Our breeding program remains true to the standard, with health and temperament being paramount.  Puppies are born and raised in our home, underfoot, using positive socialization experiences based on Avidog and Puppy Culture theories.  

Visitors are welcome!



All Casselcreek dogs are fully health-tested with a DNA screening panel, OFA x-rays for hips and elbows, and annual CERF (eye) exams, and are placed with a full health guarantee.
