Q. & A. with Sandra
Why did you start breeding?
It just seemed to be a logical next step as I became involved in the world of dog sports. I also love the process of studying and analyzing pedigrees. I truly love what I do and find joy in sharing my love of these wonderful dogs with others.What makes your program special?
I strive for a "working" Bullmastiff, one that fits the standard, with a sound athletic body and willing temperament. I truly love the Bullmastiff breed and am dedicated to looking out for the breed as a whole. I know the health and status of every dog I have bred and am proud of the temperament and conformation of my puppies. I can provide extensive knowledge and guidance for any family looking to adopt one of these wonderful dogs.Where do your breeding dogs live?
They live in my home.
