The Knallhart Story
Knallhart Kennels & Training Academy was built on a simple truth:
Most dog issues are relationship issues.
Founder and Lead Trainer Chelsey Montgomery-Gusta created Knallhart to give owners the clarity, structure, and psychology-based education they need to build balanced, trustworthy partnerships with their dogs.
We specialize in:
- Board & Train
- Service Dog Development
- Behavioral Rehabilitation
- Ethical Preservation Breeding
- Owner Coaching & Education
Every method is balanced, proven, and designed for real-world success.
Get to know our family
Knallhart is powered by the Montgomery-Gusta family—Chelsey, Dillon, Calvin, and Miles. Our dogs are raised in our home, not in kennels, giving every puppy calm exposure to family life, structure, and confident adult dogs.
This hands-on approach creates emotionally balanced puppies who transition easily into their new homes. When you join Knallhart, you become part of a family committed to excellence, integrity, and lifelong support—for you and your dog.
Earning your trust, is our top priority
