1. My name is Leona Sibo and I live in Valparaiso, Indiana. I’ve always had dogs in my life, but I’ve been actively showing dogs for around 40 years. I’ve been breeding for about 30 years, focusing on Doberman Pinschers for the past 13 years. My kennel name is Denali, and I breed with the goal of producing healthy, correct, and capable Dobermans that can succeed in both the ring and in the home.

2. A correct Doberman should be square, muscular, and balanced, with proper angles and movement. Their structure isn’t just about beauty—it’s about function. A Doberman should have the power and drive to do the work they were originally bred for. Movement, a strong topline, good feet, correct teeth, and clean angles all contribute to the breed’s working ability. If we lose those hallmarks, we lose what makes the Doberman unique and capable.

3. Yes, I believe there are enough puppy homes. But with a Working Breed like the Doberman, you need to be responsible, screen thoroughly, and educate future buyers to ensure these homes are ready and the right fit for a forever home.

4. As a breeder, I’ve incorporated several technologies to support my program. I use Embark genetic testing on all my dogs, and I believe strongly in regular health monitoring—yearly blood work, echocardiograms, and even Holter monitors every six months in some cases. These tools help us stay ahead of serious health issues like DCM. I don’t believe DCM is entirely genetic—I think there’s more to the story, possibly related to diet or deficiencies. That’s why I also focus on the best supplements and nutrition for heart support. I make sure every puppy leaves with a proper microchip and is started with the tools they need for long-term success. On the communication side, I stay connected with other breeders, owners, and puppy buyers through social media, calls, texts, and emails. It’s important to build relationships and educate the public on our breed.

5. Yes, unfortunately, I’ve noticed a decline in interest when it comes to well-bred, purposefully bred, purebred dogs. Many people are turning to backyard breeders or trendy mixes like doodles, often without understanding the long-term health, temperament, and predictability that come with a responsibly bred purebred dog. It’s frustrating at times, especially when people don’t realize how much time, effort, and care goes into breeding ethically and preserving the breed. Education is key—we need to continue showing the value of doing things the right way and explaining why breed preservation matters.

6. One trend that concerns me is the future of the sport as a whole. We’re not seeing the same size entries at shows, and the sport isn’t growing like it used to. I think a big part of that is the lack of support and mentorship for Juniors and newer exhibitors. We must do more to ensure they feel welcome, included, and prepared. Without the next generation, this sport will fade. It’s our responsibility to keep it going.

7. One of the best changes I’ve seen is the growing recognition of owner-handlers. More judges are rewarding quality dogs handled by their owners, and that’s really encouraging for the sport. I’ve also seen an increase in transparency when it comes to health—people are talking more openly about the issues in our breed, especially DCM, and working together to find solutions. Another significant trend is how many professional handlers are stepping up to mentor young people. There’s more kindness, better sportsmanship, and a greater sense of community in many rings now. At the end of the day, we do this for the love of the breed and the love of our dogs, and I think that message is being felt more strongly now than ever.
