Q. & A. with Cassie
Why did you start breeding?
Our foundation in the Boxer breed began in 2015. After instantly falling for their unique charm, we felt a calling to share that same joy with other families. We have since dedicated ourselves to performing rigorous health testing of our boxers, lifelong learning, and competing in conformation and dog sports. These efforts ensure our Boxers excel in health, temperament, and structural integrity.What makes your program special?
We are committed to raising exceptional puppies by prioritizing three core pillars: Health & Longevity: Comprehensive health testing to ensure your pup has a strong start Temperament: Focusing on the breed’s "goofy charm" & intelligence Versatility: Proving their adaptability, our dogs excel in both show & sports Our ultimate goal: to connect every healthy, happy puppy with a loving forever homeWhat are the different breed coat colors in your program?
Our puppies include fawn and brindle. Colors will vary depending on the parent dogs.Where do your breeding dogs live?
They live in my home.
