There’s a New Way to Train Your Dog — One That Actually Works for Both of You

If you’ve ever felt like dog training was confusing, inconsistent, or just didn’t “click” with your lifestyle… you're not alone.

Most owners just want a calm, confident dog who listens — one they can trust in public, welcome into new environments, or even take into service or sport work if they choose.

But between outdated dominance methods and unrealistic TikTok tricks, the advice out there feels either too harsh… or too vague to work in real life.

That’s where we come in.

At Harley & Sergio Dog Training (SK9), we use a unique, relationship-first training system that teaches both you and your dog how to communicate clearly, calmly, and consistently — so your dog actually wants to work with you.

We call it the SK9 Method™, and it’s designed for real people, real schedules, and real results.

And yes — it works whether your goal is basic obedience, behavior rehab, advanced service work, or competitive sport training.

Best part?

You don’t need hours of daily drills.
You don’t need to be a “pack leader".
You don’t need to “alpha roll” or dominate your dog.
And you definitely don’t need to figure it all out alone.
All you need is a few focused minutes a day — and the SK9 Method™.

With flexible formats (private lessons, group classes, virtual coaching, and more), we meet you where you are — whether that’s on your couch or on the competition field.

So if you’re ready to turn your dog into the calm, focused, high-performing companion you’ve always wanted…

…and do it with clarity, kindness, and confidence…

Let’s get started

About Sergio – “The K9 Coach”

Teaching Humans. Training Dogs. Growing Together.

Meet Sergio Esquivel, founder of Harley & Sergio Dog Training and the driving force behind the SK9 Method™ — a clear, compassionate system that turns chaos into calm, and confusion into connection.

A retired Marine and certified NePoPo® Silver School graduate, Sergio’s journey started with his own service dog, Harley, and quickly evolved into a lifelong passion for helping others. Trained under master dog trainer Nate Schoemer and actively competing in French Ring and Dock Diving, Sergio brings elite-level expertise — without the ego.

He’s not just here to “fix” your dog — he’s here to teach you how to lead, communicate, and thrive as a team.

Harley

Harley Von Wolfram

Hey friends! Let’s give a big round of paws for Harley—the original, the legend, and the heart of Harley and Sergio Dog Training in Corpus Christi, TX. Harley is the ultimate big sister and the one who started it all. Gifted to Sergio by fellow veteran Nate Schoemer, she’s not only his trusted service dog but also the seasoned demo dog who sets the standard for the entire team.

Harley is sweet, playful, and fiercely loyal, with a natural ability to read the room and lead with confidence. Whether she’s showing off training techniques or guiding the younger pups—Teddy, Fozzie, and Maple—Harley brings calm, clarity, and experience to every session.

She’s earned her Fetch Novice and Trick Novice titles and is currently working toward her Dock Diving titles, along with her Brevet in both French Ring and Mondio Ring. Versatile, driven, and always ready to work, Harley truly does it all—and with style.

As she continues to lead the pack, Harley is also stepping into a mentoring role, letting the next generation rise while she keeps everything running smoothly behind the scenes. We’re beyond proud of everything she’s accomplished and can’t wait to see her continue inspiring dogs and humans alike.

Teddy

Stuffed Bear Du Poilu

Meet Teddy, the spirited service dog in training who’s learning the ropes under Harley’s watchful eye. Bursting with energy and personality, Teddy brings enthusiasm to everything he does—whether he’s play-biting, wrestling with his packmates, or sprinting outside with a stolen shoe. But behind the mischief is a dog with serious drive and heart.

Teddy is a versatile and well-rounded athlete. He’s already earned his Brevet in French Ring, along with titles in AKC Canine Good Citizen (CGC), Fetch Novice, and Trick Novice. He’s currently preparing to compete in French Ring I, training for his Brevet in Mondio Ring, and chasing Dock Diving titles.

With his strong work ethic and growing skill set, Teddy is rising fast. As Harley gradually shifts into a leadership role, Teddy is stepping up—ready to lead the pack and carry forward her legacy with his own unique spark.

Fozzie

Unstuffed Bear Du Poilu

Hey everyone! Meet Unstuffed Bear Du Poilu—but we just call him Fozzie. He’s the newest up-and-comer at Harley and Sergio Dog Training in Corpus Christi, TX and well on his way to becoming our next star demo dog. Fozzie may start off shy, but hand him a tug toy and his confidence explodes. Playful, curious, and full of potential, he’s quickly finding his rhythm and growing into his role.

He’s currently working on his AKC Canine Good Citizen (CGC), Trick Dog, and Fetch titles, while also training for his Brevet in both French Ring and Mondio Ring. Fozzie’s also diving into Dock Diving—literally—and loving every splash along the way.

We’re building a strong foundation, taking things slow and steady so Fozzie can grow into a confident, well-rounded dog ready to take on any challenge. His journey is just beginning, and we’re excited to see where it leads.

Maple

Say hello to Maple—the newest (and fluffiest) member of our team. This outgoing Doodle brings a burst of joy and energy everywhere she goes, and she’s already becoming a favorite around Harley and Sergio Dog Training in Corpus Christi, TX.

Unlike her big brother Fozzie, Maple is a social butterfly from the start. She’s bubbly, fearless, and ready to make friends with everyone she meets. While she hasn’t quite caught on to tug just yet, she’s learning fast with the help of her older siblings.

Maple is currently training toward her AKC Canine Good Citizen (CGC), Trick Dog, and Fetch titles, and she’s already making waves in Dock Diving. With her people-loving personality and gentle nature, we’re also guiding her toward becoming a certified therapy dog.

She’s a bright light with a big heart, and we can’t wait to watch her grow into her role and share her sweetness with the world.

"I made a google account for the exact reason of writing this review. Sergio was professional with both my wife and I and was exceptional with our puppy. Within one session she went from a leash spaz lab to a disciplined walking companion. He also gave us the tools to continue the training without him. Thanks Sergio!"
