Meet the breeder
I'm Cassity B., the breeder behind Bastian Mountain Dogs located in Colorado Springs, CO. The loyalty and loving disposition of this breed are simply the best! We put a great deal of effort into raising our litters to ensure our puppy families will have the best experience raising their new family members.
Q. & A. with Cassity
Why did you start breeding?
My parents breed Golden Retrievers. I’ve always enjoyed helping them with advertising and raising the puppies. Seeing people be so happy with the puppies they got from them, getting second puppies, and referring friends is what made me decide I wanted to start breeding amazing dogs as well.What makes your program special?
Xena has Excellent rated hips which were done at 3 1/2 years old. I am also new to breeding and very open to new ideas and points of view, but still am backed by my parents’ 9 years of experience. If you want your puppies hind dew claws left on, them raised a certain way, certain types of pictures of your puppy weekly to complete a trend, etc., I am more than happy to accommodate.Where do your breeding dogs live?
They live in my home.
