About Us

SISU Can be loosely translated from Finnish as "strength and stubborn determination" combined with "stamina and courage" - especially when overcoming obstacles.


We welcomed our first Mastiff into our family in 2006. Although we had shared our home with several dogs and cats throughout our lives, this was the first time we had ventured into the world of showing dogs.  Tess was our introduction to conformation shows and show we did. 

Our dogs are an important part of our family and spend their time with us in the home. 

We health test our dogs and believe it is a valuable tool when choosing to breed. We do not breed often but when we do, it has been a well thought out decision.

​We are members of The Canadian Mastiff Club and The Mastiff Club of America. 

​We are located an hour east of Vancouver in the mountains of Mission, B.C. Canada



What the Lion is to the Cat the Mastiff is to the Dog, the noblest of the family; he stands alone, and all others sink before him. His courage does not exceed his temper and generosity, and in attachment he equals the kindest of his race.
